NUCLEAR REGULATORY COMMISSION
Biweekly Notice; Applications and Amendments to Facility
Operating Licenses Involving No Significant Hazards Considerations
I. Background
Pursuant to Public Law 97-415, the U.S. Nuclear Regulatory
Commission (the Commission or NRC staff) is publishing this regular
biweekly notice. Public Law 97-415 revised section 189 of the Atomic
Energy Act of 1954, as amended (the Act), to require the Commission to
publish notice of any amendments issued, or proposed to be issued,
under a new provision of section 189 of the Act. This provision grants
the Commission the authority to issue and make immediately effective
any amendment to an operating license upon a determination by the
Commission that such amendment involves no significant hazards
consideration, notwithstanding the pendency before the Commission of a
request for a hearing from any person.
This biweekly notice includes all notices of amendments issued, or
proposed to be issued from November 20, 1999, through December 3, 1999.
The last biweekly notice was published on December 1, 1999 (64 FR
67330).
Notice of Consideration of Issuance of Amendments to Facility
Operating Licenses, Proposed No Significant Hazards Consideration
Determination, and Opportunity for a Hearing
The Commission has made a proposed determination that the following
amendment requests involve no significant hazards consideration. Under
the Commission's regulations in 10 CFR 50.92, this means that operation
of the facility in accordance with the proposed amendment would not (1)
involve a significant increase in the probability or consequences of an
accident previously evaluated; or (2) create the possibility of a new
or different kind of accident from any accident previously evaluated;
or (3) involve a significant reduction in a margin of safety. The basis
for this proposed determination for each amendment request is shown
below.
The Commission is seeking public comments on this proposed
determination. Any comments received within 30 days after the date of
publication of this notice will be considered in making any final
determination.
Normally, the Commission will not issue the amendment until the
expiration of the 30-day notice period. However, should circumstances
change during the notice period such that failure to act in a timely
way would result, for example, in derating or shutdown of the facility,
the Commission may issue the license amendment before the expiration of
the 30-day notice period, provided that its final determination is that
the amendment involves no significant hazards consideration. The final
determination will consider all public and State comments received
before action is taken. Should the Commission take this action, it will
publish in the Federal Register a notice of issuance and provide for
opportunity for a hearing after issuance. The Commission expects that
the need to take this action will occur very infrequently.
Written comments may be submitted by mail to the Chief, Rules
Review and Directives Branch, Division of Freedom of Information and
Publications Services, Office of Administration, U.S. Nuclear
Regulatory Commission, Washington, DC 20555-0001, and should cite the
publication date and page number of this Federal Register notice.
Written comments may also be delivered to Room 6D22, Two White Flint
North, 11545 Rockville Pike, Rockville, Maryland from 7:30 a.m. to 4:15
p.m. Federal workdays. Copies of written comments received may be
[[Page 70078]]
examined at the NRC Public Document Room, the Gelman Building, 2120 L
Street, NW., Washington, DC. The filing of requests for a hearing and
petitions for leave to intervene is discussed below.
By January 14, 2000, the licensee may file a request for a hearing
with respect to issuance of the amendment to the subject facility
operating license and any person whose interest may be affected by this
proceeding and who wishes to participate as a party in the proceeding
must file a written request for a hearing and a petition for leave to
intervene. Requests for a hearing and a petition for leave to intervene
shall be filed in accordance with the Commission's ``Rules of Practice
for Domestic Licensing Proceedings'' in 10 CFR Part 2. Interested
persons should consult a current copy of 10 CFR 2.714 which is
available at the Commission's Public Document Room, the Gelman
Building, 2120 L Street, NW., Washington, DC, and electronically from
the ADAMS Public Library component on the NRC Web site, http://
www.nrc.gov (the Electronic Reading Room). If a request for a hearing
or petition for leave to intervene is filed by the above date, the
Commission or an Atomic Safety and Licensing Board, designated by the
Commission or by the Chairman of the Atomic Safety and Licensing Board
Panel, will rule on the request and/or petition; and the Secretary or
the designated Atomic Safety and Licensing Board will issue a notice of
a hearing or an appropriate order.
As required by 10 CFR 2.714, a petition for leave to intervene
shall set forth with particularity the interest of the petitioner in
the proceeding, and how that interest may be affected by the results of
the proceeding. The petition should specifically explain the reasons
why intervention should be permitted with particular reference to the
following factors: (1) the nature of the petitioner's right under the
Act to be made a party to the proceeding; (2) the nature and extent of
the petitioner's property, financial, or other interest in the
proceeding; and (3) the possible effect of any order which may be
entered in the proceeding on the petitioner's interest. The petition
should also identify the specific aspect(s) of the subject matter of
the proceeding as to which petitioner wishes to intervene. Any person
who has filed a petition for leave to intervene or who has been
admitted as a party may amend the petition without requesting leave of
the Board up to 15 days prior to the first prehearing conference
scheduled in the proceeding, but such an amended petition must satisfy
the specificity requirements described above.
Not later than 15 days prior to the first prehearing conference
scheduled in the proceeding, a petitioner shall file a supplement to
the petition to intervene which must include a list of the contentions
which are sought to be litigated in the matter. Each contention must
consist of a specific statement of the issue of law or fact to be
raised or controverted. In addition, the petitioner shall provide a
brief explanation of the bases of the contention and a concise
statement of the alleged facts or expert opinion which support the
contention and on which the petitioner intends to rely in proving the
contention at the hearing. The petitioner must also provide references
to those specific sources and documents of which the petitioner is
aware and on which the petitioner intends to rely to establish those
facts or expert opinion. Petitioner must provide sufficient information
to show that a genuine dispute exists with the applicant on a material
issue of law or fact. Contentions shall be limited to matters within
the scope of the amendment under consideration. The contention must be
one which, if proven, would entitle the petitioner to relief. A
petitioner who fails to file such a supplement which satisfies these
requirements with respect to at least one contention will not be
permitted to participate as a party.
Those permitted to intervene become parties to the proceeding,
subject to any limitations in the order granting leave to intervene,
and have the opportunity to participate fully in the conduct of the
hearing, including the opportunity to present evidence and cross-
examine witnesses.
If a hearing is requested, the Commission will make a final
determination on the issue of no significant hazards consideration. The
final determination will serve to decide when the hearing is held.
If the final determination is that the amendment request involves
no significant hazards consideration, the Commission may issue the
amendment and make it immediately effective, notwithstanding the
request for a hearing. Any hearing held would take place after issuance
of the amendment.
If the final determination is that the amendment request involves a
significant hazards consideration, any hearing held would take place
before the issuance of any amendment.
A request for a hearing or a petition for leave to intervene must
be filed with the Secretary of the Commission, U.S. Nuclear Regulatory
Commission, Washington, DC 20555-0001, Attention: Docketing and
Services Branch, or may be delivered to the Commission's Public
Document Room, the Gelman Building, 2120 L Street, NW., Washington DC,
by the above date. Where petitions are filed during the last 10 days of
the notice period, it is requested that the petitioner promptly so
inform the Commission by a toll-free telephone call to Western Union at
1-(800) 248-5100 (in Missouri 1-(800) 342-6700). The Western Union
operator should be given Datagram Identification Number N1023 and the
following message addressed to (Project Director): petitioner's name
and telephone number, date petition was mailed, plant name, and
publication date and page number of this Federal Register notice. A
copy of the petition should also be sent to the Office of the General
Counsel, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001,
and to the attorney for the licensee.
Nontimely filings of petitions for leave to intervene, amended
petitions, supplemental petitions and/or requests for a hearing will
not be entertained absent a determination by the Commission, the
presiding officer or the Atomic Safety and Licensing Board that the
petition and/or request should be granted based upon a balancing of
factors specified in 10 CFR 2.714(a)(1)(i)-(v) and 2.714(d).

Baltimore Gas and Electric Company, Docket No. 50-317, Calvert Cliffs
Nuclear Power Plant, Unit No. 1, Calvert County, Maryland
Date of amendment request: November 18, 1999.
Description of amendment request: The proposed amendment revises
the Unit 1 Heatup Curve (Technical Specification Figure 3.4.3-1), Unit
1 Cooldown Curve (Technical Specification Figure 3.4.3-2), and Unit 1
Maximum Power-Operated Relief Valve (PORV) Opening Pressure vs
Temperature Curve (Technical Specification Figure 3.4.12-1) to change
fluence level from 2.61 x 10\19\ n/cm \2\ to 4.49 x 1019 n/cm \2\
(E>1MeV). This change reflects the new actual fluence level for which
these curves are valid, and is necessary to extend the
[[Page 70079]]
applicability of the curves for Unit 1 operation.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Would not involve a significant increase in the probability
or consequences of an accident previously evaluated.
In accordance with 10 CFR Part 50, Appendix G, the Calvert
Cliffs pressure/temperature (P-T) limits for material fracture
toughness requirements of the reactor coolant pressure boundary
materials were developed using the methods of linear elastic
fracture mechanics and the guidance found in the American Society of
Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Section
III, Appendix G. The Calvert Cliffs (P-T) limits are based on
fluence level. The fluence level corresponds to the pressurized
thermal shock (PTS) screening criteria defined in 10 CFR 50.61 for
the critical elements. Methods described in the Nuclear Regulatory
Commission Regulatory Guide 1.99, Revision 2, are used to predict
the embrittlement effect of neutron irradiation on reactor vessel
materials. Regulatory Guide 1.99 defines embrittlement effect in
terms of adjusted reference temperatures (ART), which depends on the
material property of the PTS critical element.
The proposed higher fluence level for the Technical
Specification P-T limits was made possible by the identification of
a new 10 CFR 50.61 critical element for fracture toughness
requirements for protection against PTS events. The material
properties of the new critical element resulted in an increase in
fluence level from 2.61 x 10 \19\ n/cm \2\ to 4.49 x 1019 n/cm \2\
for the ART valves calculated using the material properties of the
old PTS critical element. the P-T limits analysis remain well within
the conservative acceptance limits of the ASME Boiler and Pressure
Vessel Code, Section III, Appendix G. Hence, with the new higher
fluence level, the 10 CFR Part 50, Appendix G, requirement for
adequate margin to brittle failure during normal operation,
anticipated operational occurrences, and system hydrostatic tests,
for the reactor coolant pressure boundary materials, is maintained.
Therefore the proposed change does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. Would not create the possibility of a new or different type
of accident from any accidents previously evaluated.
The implementation of the proposed revision has no significant
effect on either the configuration of the plant, or the manner in
which it is operated.
Therefore, the proposed change does not create the possibility
of a new or different kind of accident from any previously
evaluated.
3. Would not involve a significant reduction in a margin of
safety.
As discussed above, the P-T limits analysis remain well within
the conservative acceptance limits of the ASME Boiler and Pressure
Vessel Code, Section III, Appendix G. Hence, with the new higher
fluence level, the 10 CFR Part 50, Appendix G, requirement for
adequate margin to brittle failure during normal operation,
anticipated operational occurrences, and system hydrostatic tests,
for the reactor coolant pressure boundary materials, is maintained.
Therefore, this proposed modification does not significantly
reduce the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Baltimore Gas and Electric Company, Docket Nos. 50-317 and 50-318,
Calvert Cliffs Nuclear Power Plant, Unit Nos. 1 and 2, Calvert County,
Maryland
Date of amendments request: November 19, 1999.
Description of amendments request: The amendments request approval
of changes in the Updated Final Safety Analysis Report (UFSAR) that
constitute an unreviewed safety question (USQ) as described in 10 CFR
50.59. Specifically, these changes would be an increase in the
probability of occurrence of malfunction. Additionally, these changes
were not previously evaluated in the UFSAR.
Regulations require that structures, systems, and components
important to safety be appropriately protected against the effects of
effects of missiles that might result from equipment failures. Failures
that could occur in the large turbines of the main turbine-generator
sets have the potential for producing large high-energy missiles
(hereinafter called ``turbine missiles''). Both of Baltimore Gas and
Electric Company's (BGE) turbine generator suppliers studied the
failure of the rotating elements of their turbine-generators. The UFSAR
only addresses a turbine missile hitting the Containment Building,
Control Room, Switchgear Room, and Waste Processing Area. As a result
of revising the Unit 1 and Unit 2 turbine missile analysis, BGE
determined that the discussion of turbine missiles in Section 5.3.1 of
the UFSAR was incomplete. Specifically, it did not discuss the
probability of a missile from the Unit 1 turbine-generator striking: 1)
the refueling water tanks; 2) the No. 11 Fuel Oil Storage Tank; or 3)
plant equipment through various roof slabs or through non-missile-proof
openings in the missile-proof walls. When these additional targets are
included, the total target area is increased. If the target area
increases, the probability of a turbine missile causing equipment
damage increases. It is this increase in probability that leads to a
USQ for a turbine missile from Unit 1. Note that by using methodologies
previously approved by NRC, the revised analysis concludes there is no
USQ for turbine missiles from the Unit 2 turbine-generator.
The UFSAR change is considered a USQ for Units 1 and 2 because the
results of the revised Unit 1 turbine missile analysis for the
following unprotected rooms or components show an increase in
probability of occurrence of malfunction not previously evaluated in
the UFSAR:
the Refueling Water Tanks;
the No. 11 Fuel Oil Storage Tank (non-missile-proof);
the saltwater pumps through roof hatches in the Intake Structure
roof;
the roof slabs over the refueling Water Tank Pump Room, the Control
Room Heating, Ventilation, and Air Conditioning (HVAC) Equipment Room,
the Spent Fuel Pool Area Ventilation Equipment room, and a portion of
118 level roof over the fuel cask handling area;
the Control Room HVAC Room through its non-missile-proof door; and
the Unit 1 Auxiliary Building 45 Switchgear Room through
the its non-missile-proof doors.
The probability of a missile from the Unit 1 turbine-generator
striking them is a negligible increase in the probability of occurrence
of malfunction of equipment associated with Unit 1 and 2. Upon approval
of this request, the UFSAR will be revised to reflect the proposed
turbine missile description. There is no USQ associated with the Unit 2
turbine-generator.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Would not involve a significant increase in the probability
or consequences of an accident previously evaluated.
Regulations require that structures, systems, and components
important to safety be appropriately protected against the effects
of missiles that might result from equipment failures. Further that
could occur in the large turbines of the main turbine-generator sets
have the potential for producing large high-
[[Page 70080]]
energy missiles (hereinafter called turbine missiles). Both of our
turbine-generator suppliers studied the failure of the rotating
elements of their turbine-generators. The UFSAR only addresses
turbine missile hitting the Containment Building, Control Room,
Switchgear Room, and Waste Processing Area. As result of revising
the Unit 1 and Unit 2 turbine missile analysis, we determined that
the discussion of turbine missiles of the UFSAR was incomplete. From
the revised analysis, we determined Unit 1 and 2 USQs exist for the
following unprotected rooms or components (i.e., there is an
increase in probability of occurrence of malfunction not previously
evaluated in the UFSAR):
the Refueling Water Tanks;
the No. 11 Fuel Oil Storage Tank;
the Saltwater Pumps through roof hatches in the Intake Structure
Roof;
the roof slabs over the Refueling Water Tank Pump Room, the
Control Room Heating, Ventilation, and Air Conditioning (HVAC)
Equipment Room, Spent Fuel Pool Area Ventilation Equipment Room, and
a portion of 118' level roof over the cask handling area;
the Control Room HVAC Room through its non-missile-proof door;
and,
the Unit 1 Auxiliary Building 45' Switchgear Room through its
non-missile-proof doors.
The probability of a missile from the Unit 1 turbine-generator
striking them is a negligible, but greater than zero, increase in
the probability of occurrence of malfunction of equipment associated
with Units 1 and 2.
For Unit 1 High Trajectory Missiles (HTM), the guidance of NUREG
0800, Standard Review Plan, is used as one acceptable method for
evaluating the risk. Use of this method is not a commitment to the
Standard Review Plan and does not incorporate the Standard Review
Plan into our licensing basis. The revised analysis shows that the
total target area considered vulnerable to an HTM is less than the
Standard Review Plan limit of 10,000 ft2 for each unit.
Therefore, the risk form an HTM is insignificant. Note that all of
the Units 1, 2, and Common structures listed above are equally
vulnerable to a Unit 1 HTM. Therefore, any risk increase to the
plant structures constitutes a USQ for Units 1 and 2.
For Unit 1 Low-Trajectory Missiles (LTMs), protection for the
Auxiliary Building is provided by a 3' thick, concrete, missile-
proof wall between the Turbine Building and the Auxiliary building
(the K-line wall). This wall is 3' thick below the 69' elevation and
2' thick above the 69' for areas protecting safety-related
equipment. The revised analysis evaluates the protection of Unit 1
equipment from a Unit 1 LTM. The 69' Control Room HVAC Equipment
Room and Unit 1 Auxiliary Building 45' Switchgear Room are protected
by the missile-proof walls except for the openings at the non-
missile-proof doors. A turbine missile that hits one of these doors
is assumed to go through them, strike safety-related equipment in
the room, and cause it to fail. Recall that the Control Room HVAC
equipment is shared by both units. Therefore, any increase in risk
of failure of equipment in this room affects both Units 1 and 2.
The risk associated with a turbine missile to either of these
doors is calculated using guidance in Regulatory Guide 1.115,
Revision 1, ``Protection Against Low-Trajectory Turbine Missiles.''
This guidance states that the turbine missile hazard should be less
than 107. The missile hazard rate in the revised risk
analysis shows that the risk from LTMs from the Unit 1 General
Electric turbine-generator to the 69' Control Room HVAC Equipment
Room and Unit 1 Auxiliary Building 45' Switchgear room through these
non-missile-proof doors is less than 107.
Based on the above, the proposed change does not involve a
significant increase in the probability or consequences of an
accident previously evaluated.
2. Would not create the possibility of a new or different type
of accident from any accident previously evaluated.
The proposed change makes no physical changes to the plant.
Specifically, the proposed change does not add new or modify
existing plant equipment such that it could become an accident
initiator different from its current role as an accident initiator.
The only change made by this activity is the revision of the UFSAR
to include the revised turbine missile analysis. The UFSAR chapter 1
drawings correctly depict the location of plant structures and
components, including the thickness of and the openings in the
missile-proof wall between the Turbine Building and the Auxiliary
building (the K-Line Wall). Therefore, the possibility of a new or
different type of accident is not created by the proposed change.
3. Would not involve a significant reduction in a margin of
safety.
The regulations require an evaluation of turbine missiles to
ensure that structures, systems, and components important to safety
be appropriately protected from them. Revised turbine missile
analysis have been performed consistent with appropriate regulatory
guidance (Regulatory Guide 1.115 and the Standard Review Plan). The
results of the revised analysis meet the acceptance criteria of the
guidance. Therefore, the proposed change does not involve a
significant reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendments request involves no significant hazards consideration.

Carolina Power & Light Company, et al., Docket No. 50-325, Brunswick
Steam Electric Plant, Unit 1, Brunswick County, North Carolina
Date of amendment request: November 17, 1999.
Description of amendment request: The proposed amendment would
change Technical Specification (TS) 2.1.1.2, ``Reactor Core Safety
Limits.'' The minimum critical power ratios (MCPR) for single and two
recirculation loop operation would be increased. In addition, the
reference in TS 5.6.5, ``Core Operating Limits Report,'' Item b.5,
would be removed.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. The proposed license amendments do not involve a significant
increase in the probability or consequences of an accident previously
evaluated.
The proposed license amendment will establish MCPR Safety Limit
values of 1.10 for two recirculation loop operation and 1.11 for single
recirculation loop operation. Additionally, the proposed license
amendment replaces an expiring cycle-specific reference in the list of
analytical methods approved for determining core operating limits in
Specification 5.6.5.b with a reference to a GE [General Electric]
topical report which has been accepted by the NRC.
The methods for calculating the MCPR Safety Limit values have been
previously approved by the NRC and are described in GE's reload
licensing methodology topical report NEDE-24011-P-A. Use of these
methods ensures that the integrity of the fuel will be maintained
during normal operation and that the resulting MCPR Safety Limit values
satisfy the fuel design safety criteria that less than 0.1 percent of
the fuel rods experience boiling transition if the safety limits are
not violated. The change does not require any physical plant
modifications, physically affect any plant components, or allow the
plant to be operated any closer to fuel design limits. Therefore, the
proposed change to the MCPR Safety Limit values and to the list in
Specification 5.6.5.b of analytical methods approved for determining
core operating limits results no increase in the probability of a
previously evaluated accident.
The consequences of a previously evaluated accident are dependent
on the initial conditions assumed for the analysis, the behavior of the
fuel during the accident, the availability and successful functioning
of the equipment assumed to operate in response to the accident, and
the setpoints at which these actions are initiated.
[[Page 70081]]
The methods used for calculating the MCPR Safety Limits have been
approved by the NRC and are described in GE's reload licensing
methodology topical report NEDE-24011, ``General Electric Standard
Application for Reactor Fuel (GESTAR II).'' The proposed MCPR Safety
Limit values of 1.10 for two recirculation loop operation and 1.11 for
single recirculation loop operation will ensure that less than 0.1
percent of the fuel rods will experience boiling transition during any
plant operation if the limits are not violated. The proposed change to
the MCPR Safety Limit values does not affect the performance of any
equipment used to mitigate the consequences of a previously evaluated
accident. Also, the proposed change does not affect setpoints that
initiate protective or mitigative actions. No analysis assumptions are
violated and there are no adverse effects on the factors contributing
to offsite and onsite dose.
Based on the determination of the proposed MCPR Safety Limit values
using conservative NRC-approved methods and the operability of plant
systems designed to mitigate the consequences of accidents not being
changed, the proposed change to the MCPR Safety Limit values and to the
list in Specification 5.6.5.b of analytical methods approved for
determining core operating limits does not significantly increase the
consequences of a previously evaluated accident.
2. The proposed license amendments will not create the
possibility of a new or different kind of accident from any accident
previously evaluated.
Creation of the possibility of a new or different kind of
accident would require the creation of one or more new precursors of
that accident. New accident precursors may be created by
modifications of the plant configuration, including changes in
allowable modes of operation. This proposed license amendment does
not involve any physical alteration of plant systems and plant
equipment will not be operated in a different manner. As a result,
no new failure modes are being introduced. Therefore, the proposed
change to the MCPR Safety Limit values and to the list in
Specification 5.6.5.b of analytical methods approved for determining
core operating limits will not create the possibility of a new or
different kind of accident from any accident previously evaluated.
3. The proposed license amendments do not involve a significant
reduction in a margin of safety.
The margin of safety is established through the design of the
plant structures, systems, and components; through the parameters
within which the plant is operated; through the establishment of
setpoints for actuation of equipment relied upon to respond to an
event; and through margins contained within the safety analyses.
The proposed change to the MCPR Safety Limit values and the list
in Specification 5.6.5.b of analytical methods approved for
determining core operating limits does not adversely impact the
performance of plant structures, systems, components, and setpoints
relied upon to respond to mitigate an accident. As previously
stated, the methods for calculating the MCPR Safety Limit values
have been previously approved by the NRC and are described in GE's
reload licensing methodology topical report NEDE-24011-P-A. Use of
these methods ensures that the resulting MCPR Safety Limit values
satisfy the fuel design safety criteria that less than 0.1 percent
of the fuel rods experience boiling transition if the safety limits
are not violated. As a result, the proposed changes do not
significantly impact any safety analysis assumptions or results.
Based on the assurance that the fuel design safety criteria will be
met, the proposed changes do not involve a significant reduction in
a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Carolina Power & Light Company, et al., Docket No. 50-400, Shearon
Harris Nuclear Power Plant, Unit 1, Wake and Chatham Counties, North
Carolina
Date of amendment request: November 19, 1999.
Description of amendment request: The proposed amendment would
revise the Technical Specifications (TS) for the Harris Nuclear Plant
(HNP) to incorporate American Society for Testing and Materials (ASTM)
D3803-1989, ``Standard Test Method for Nuclear-Grade Activated
Carbon,'' as the standard for testing nuclear-grade activated charcoal.
Specifically, TS 4.7.6 will be revised for the Control Room Emergency
Filtration System, TS 4.7.7 will be revised for the Reactor Auxiliary
Building Emergency Exhaust System, and TS 4.9.12 will be revised for
the Fuel Handling Building Emergency Exhaust System. These changes are
being proposed in accordance with NRC Generic Letter (GL) 99-02,
``Laboratory Testing Of Nuclear-Grade Activated Charcoal,'' dated June
3, 1999.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. The proposed license amendment does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
This proposed change to revise the standard to which activated
charcoal samples are tested will ensure that testing is accurate and
repeatable. This will help ensure that the Engineered Safety Feature
(ESF) ventilation systems are capable of performing their safety
function. Therefore, the proposed changes do not involve a
significant increase in the probability or consequences of an
accident previously evaluated.
2. The proposed amendment does not create the possibility of a
new or different kind of accident from any accident previously
evaluated.
The proposed changes incorporate ASTM D3803-1989 as the testing
standard for nuclear-grade activated charcoal samples. This will
ensure that testing is accurate and repeatable. Plant structures,
systems, and components will not be operated in a different manner
as a result of these proposed changes and no physical modifications
to equipment are involved. Using the improved testing protocol does
not have the potential for creating the possibility of a new or
different type of accident from any previously evaluated.
3. The proposed amendment does not involve a significant
reduction in the margin of safety.
The proposed changes do not change the manner in which
structures, systems or components are operated. Revising the
standard to which activated charcoal samples are tested will ensure
that testing is accurate and repeatable. This will help ensure that
the ESF ventilation systems are capable of performing their safety

in the margin of safety.

Nuclear Power Station, Units 1 and 2, Rock Island County, Illinois
Date of amendment request: November 12, 1999.
Description of amendment request: The proposed change revises the
pressure-temperature limits by revising
[[Page 70082]]
the heatup, cooldown and inservice test limitations for the Reactor
Pressure Vessel to a maximum of 32 Effective Full Power Years.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Does the change involve a significant increase in the
probability of occurrence or consequences of an accident previously
evaluated?
The proposed changes do not modify the reactor coolant pressure
boundary, do not make changes in operating pressure, materials or
seismic loading. The proposed changes adjust the reference
temperature for the limiting beltline material to account for
radiation effects and provide the same level of protection as
previously evaluated. The proposed changes do not adversely affect
the integrity of the reactor coolant system (RCS) such that its
function in the control of radiological consequences is affected.
Therefore, the proposed change does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. Does the change create the possibility of a new or different
kind of accident from any accident previously evaluated?
The proposed changes do not create the possibility of a new or
different kind of accident previously evaluated for Quad Cities
Nuclear Power Station. No new modes of operation are introduced by
the proposed changes. The proposed changes will not create any
failure mode not bounded by previously evaluated accidents. Use of
the revised pressure-temperature (P-T) curves will continue to
provide the same level of protection as was previously reviewed and
approved.
Further, the proposed changes to the P-T curves do not affect
any activities or equipment, and are not assumed in any safety
analysis to initiate any accident sequence for Quad Cities Nuclear
Power Station. Therefore, the proposed changes do not create the
possibility of a new or different kind of accident from any
previously evaluated.
3. Does the change involve a significant reduction in a margin
of safety?
The proposed changes reflect an update of the P-T curves to
extend the Reactor Pressure Vessel (RPV) operating limit to 32
Effective Full Power Years (EFPY). The revised curves are based on
the latest American Society of Mechanical Engineers (ASME) guidance
and actual operational data for the units. This proposed changes are
acceptable because the ASME guidance maintains the relative margin
of safety commensurate with that which existed at the time that the
ASME Section IX Appendix G was approved in 1974. Therefore, the
proposed changes do not involve a significant reduction in the
margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
requested amendments involve no significant hazards consideration.

Date of amendment request: November 16, 1999.
Description of amendment request: The proposed change modifies the
surveillance requirements for Functional Unit 3 on Table 4.1.A-1 due to
replacement of the Reactor Pressure Vessel Steam Dome pressure switches
with analog trip units.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
Does the change involve a significant increase in the
probability of occurrence or consequences of an accident previously
evaluated?
During the upcoming refueling outages at Quad Cities Nuclear
Power Station, Unit 1 and Unit 2, a design change will be
implemented that upgrades the existing Reactor Vessel Steam Dome-
High instrumentation from a pressure switch to an analog trip unit
device. Analog trip units are proven technology that are more
reliable than existing equipment. Analog trip units are used in
various applications of Quad Cities Nuclear Power Station, including
the Reactor Protection System (RPS) low water level trip function.
The proposed change adds a CHANNEL CHECK and 31-day trip unit
calibration requirement for the Reactor Vessel Steam Dome Pressure--
High RPS trip function. This requirement is not applicable to the
existing instrumentation because the Barksdale pressure switches are
non-indicating and do not employ trip units.
Technical Specification (TS) requirements that govern
operability or routine testing of plant instruments are not assumed
to be initiators of any analyzed event because these instruments are
intended to prevent, detect, or mitigate accidents. Therefore, these
changes will not involve an increase in the probability of
occurrence of an accident previously evaluated. Additionally, these
changes will not increase the consequences of an accident previously
evaluated because the proposed change does not adversely impact
structures, systems, or components (SSCs). The planned instrument
upgrade is a more reliable design than existing equipment. The
proposed change establishes requirements that ensures components are
operable when necessary for the prevention or mitigation of
accidents or transients. Furthermore, there will be no change in the
types or significant increase in the amounts of any effluents
released offsite. For these reasons, the proposed changes do not
involve a significant increase in the probability or consequences of
an accident previously evaluated.
Does the change create the possibility of a new or different
kind of accident from any accident previously evaluated?
The proposed changes support a planned instrumentation upgrade
by incorporating Surveillance Requirements required to ensure
operability. The change does not adversely impact the manner in
which the instrument will operate under normal and abnormal
operating conditions. Therefore, these changes provide an equivalent
level of safety and will not create the possibility of a new or
different kind of accident from any accident previously evaluated.
The changes in methods governing normal plant operation are
consistent with the current safety analysis assumptions. Therefore,
these changes will not create the possibility of a new or different
kind of accident from any accident previously evaluated.
Does the change involve a significant reduction in a margin of
safety?
The proposed change supports a planned instrumentation upgrade.
The proposed change does not affect the probability of failure or
availability of the affected instrumentation. The addition of a
CHANNEL CHECK and 31-day trip unit calibration for RPS Functional
Unit 3 (Reactor Vessel Steam Dome Pressure--High) is a conservative
change that aligns the surveillance requirements for a planned
instrumentation upgrade with that of similar instrumentation.
Therefore, it is concluded that the proposed changes will not result
in a reduction in the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are

Energy Northwest, Docket No. 50-397, WNP-2, Benton County, Washington
Date of amendment request: October 13, 1999.
Description of amendment request: The proposed amendment would
revise Technical Specification (TS) 3.3.6.1, Table 3.3.6-1, ``Primary
Containment
[[Page 70083]]
Isolation Instrumentation.'' This amendment requests that Function 5 on
Table 3.3.6-1, ``RHR SDC System Isolation,'' be modified by removing
footnote (d). Footnote (d) states, ``Only the inboard trip system is
required in Modes 1, 2, and 3, as applicable, when the outboard valve
control is transferred to the alternate remote shutdown panel and the
outboard valve is closed.'' The outboard suction valve, RHR-V-8, is no
longer used as a high/low pressure interface in the residual heat
removal (RHR) system. Valve RHR-V-9, which is in series with valve RHR-
V-8, is now used as the high/low pressure interface valve. Valve RHR-V-
9 is operable in all modes of operation and therefore, footnote (d) is
no longer needed. The current footnote (e) will be relettered as
footnote (d) for consistency.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. The proposed change does not involve a significant increase
in the probability or consequences of an accident previously
evaluated.
This change involves the probability and consequences of
accidents associated with the isolation of the RHR SDC [shutdown
cooling] mode of RHR operation. Isolation is provided if high
temperatures occur in RHR pump rooms or heat exchanger areas, if
reactor vessel water level is low, or if reactor vessel pressure is
high.
FSAR [Final Safety Analysis Report] Chapter 15, ``Accident
Analysis,'' describes two events associated with the RHR system
during SDC operation. FSAR Section 15.1.6, ``Inadvertent Residual
Heat Removal Shutdown Cooling Operation,'' describes the impact of
system operation during startup or cool-down when the reactor is
near critical. The proposed change removes the exemption for the
second trip system to isolate RHR SDC operation. There will be no
change in the probability or consequences of this accident as a
result of the proposed change.
The second accident is described in FSAR Section 15.2.9,
``Failure of Residual Heat Removal Shutdown Cooling.'' It postulates
the failure of the RHR system to function in SDC mode. The
evaluation assumes a failure of the SDC mode of operation but does
not disable the remaining modes of RHR operation. The alternate SDC
paths involve the use of the safety relief valves to establish a
cooling flow path to the containment suppression pool. That
evaluated accident does not result in any fuel failure. The proposed
change will not result in an increase in the probability of fuel
failures. The evaluated accident does result in normal coolant
activity being released to the suppression pool through the safety
relief valves. The proposed activity will not result in a change in
the release of this coolant activity. The proposed change requires
the removal of the exemption for the second trip system to isolate
SDC and will have no impact on the probability or consequences of
that accident.
Therefore, the operation of WNP-2 in accordance with the
proposed amendment will not involve a significant increase in the
probability or consequences of an accident previously evaluated.
2. The proposed change does not create the possibility of a new
or different kind of accident from any accident previously
evaluated.
The proposed change will not cause any new inadvertent SDC
startup, loss of water inventory or loss of coolant accidents
(LOCA). New or different inadvertent RHR SDC startup accidents are
not possible because this change is only a further restriction on
system operation. The LOCA during Mode 3 is bounded by the LOCA
defined for Modes 1 and 2. No new primary system LOCA can be
initiated because of this change.
Therefore, the operation of WNP-2 in accordance with the
proposed amendment will not create the possibility of a new or
different kind of accident from any accident previously evaluated.
3. The proposed change does not involve a significant reduction
in a margin of safety.
The removal of an exemption for the second trip system, as
proposed by this change, will increase the probability that leaks
and high pressure will be isolated. Therefore, operation of WNP-2 in
accordance with the proposed amendment will not decrease the margin
of safety. Therefore, the operation of WNP-2 in accordance with the
proposed amendment will not involve a significant reduction in the
margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Entergy Gulf States, Inc., and Entergy Operations, Inc., Docket No. 50-
458, River Bend Station, Unit 1 (RBS), West Feliciana Parish, Louisiana
Date of amendment request: October 25, 1999.
Description of amendment request: The proposed license amendment
would revise the reactor pressure vessel (RPV) surveillance capsule
withdrawal schedule for the River Bend Station. The first surveillance
capsule would be withdrawn at 13.4 effective full power years (EFPY)
rather than 10.4 EFPY.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. The proposed changes do not involve a significant increase in
the probability or consequences of an accident previously evaluated.
Pressure-temperature (P/T) limits (RBS Technical Specifications
Figure 3.4.11-1) are imposed on the reactor coolant system to ensure
that adequate safety margins against nonductile or rapidly
propagating failure exist during normal operation, anticipated
operational occurrences, and system hydrostatic tests. The P/T
limits are related to the nil-ductility reference temperature,
RTNDT, as described in ASME [American Society of
Mechanical Engineers] Section III, Appendix G. Changes in the
fracture toughness properties of RPV beltline materials, resulting
from the neutron irradiation and the thermal environment, are
monitored by a surveillance program in compliance with the
requirements of 10 CFR [Part] 50, Appendix H. The effect of neutron
fluence on the shift in the nil-ductility reference temperature of
pressure vessel steel is predicted by methods given in RG
[Regulatory Guide] 1.99, [Revision] 2.
River Bend's current P/T limits, as well as those for the
planned increase in reactor thermal power (``Power Uprate''), were
established based on adjusted reference temperatures developed in
accordance with the procedures prescribed in RG 1.99, [Revision] 2,
Regulatory Position 1. Calculation of adjusted reference temperature
by these procedures includes a margin term to ensure conservative,
upper-bound values are used for the calculation of the P/T limits.
Revision of the first capsule withdrawal schedule will not affect
the P/T limits because they will continue to be established in
accordance with Regulatory Position 1 or other NRC [Nuclear
Regulatory Commission]-approved procedures. When permitted (two or
more credible surveillance data sets available), Regulatory Position
2 (or other NRC-approved) methods for determining adjusted reference
temperature will be followed.
This change is not related to any accidents previously
evaluated. The proposed change is a revision of the first
surveillance capsule withdrawal time, identified in TRM [Technical
Requirements Manual] Table 3.4.11-1, from 10.4 EFPY to 13.4 EFPY.
This change will not affect P/T limits as given in RBS Technical
Specifications Figure 3.4.11-1 or USAR Figures 5.3-4a and 5.3-4b.
This change will not affect any plant safety limits or limiting
conditions of operation. The proposed change will not affect reactor
pressure vessel performance as no physical changes are involved and
RBS vessel P/T limits will remain conservative in accordance with RG
1.99, [Revision] 2 requirements. The proposed change will not cause
the reactor pressure vessel or interfacing systems to be operated
outside of their design or testing limits. Also, the proposed change
will not alter any assumptions previously made in evaluating the
radiological consequences of accidents. Therefore, the probability
or
[[Page 70084]]
consequences of accidents previously evaluated will not be increased
by the proposed change.
2. The proposed changes do not create the possibility of a new
or different kind of accident from any accident previously
evaluated.
The proposed change revises the first RPV material surveillance
capsule withdrawal time in TRM Table 3.4.11-1 from 10.4 EFPY to 13.4
EFPY. This proposed change does not involve a modification of the
design of plant structures, systems, or components. The proposed
change will not impact the manner in which the plant is operated as
plant operating and testing procedures will not be affected by the
change. The proposed change will not degrade the reliability of
structures, systems, or components important to safety (ITS) as
equipment protection features will not be deleted or modified,
equipment redundancy or independence will not be reduced, supporting
system performance will not be downgraded, the frequency of
operation of ITS equipment will not be increased, and increased or
more severe testing of ITS equipment will not be imposed. No new
accident types or failure modes will be introduced as a result of
the proposed change. Therefore, the proposed change does not create
the possibility of a new or different kind of accident from that
previously evaluated.
3. The proposed changes do not involve a significant reduction
in a margin of safety.
As stated in Section 5.3.2 of the River Bend Safety Evaluation
Report (NUREG-0989), ``Appendices G and H of 10 CFR [Part] 50
describe the conditions that require pressure-temperature limits and
provide the general bases for these limits. These appendices
specifically require that pressure-temperature limits must provide
safety margins at least as great as those commended in the ASME Code
[American Society of Mechanical Engineers Boiler and Pressure Vessel
Code], Section III, Appendix G. * * * Until the results from the
reactor vessel surveillance program become available, the staff will
use Regulatory Guide (RG) 1.99, Revision 1 [now Revision 2], to
predict the amount of neutron irradiation damage.* * * The use of
operating limits based on these criteria--as defined by applicable
regulations, codes, and standards--will provide reasonable assurance
that nonductile or rapidly propagating failure will not occur, and
will constitute an acceptable basis for satisfying the applicable
requirements of General Design Criteria (GDC) 31.''
Bases for RBS Technical Specification 3.4.11 states: ``The P/T
limits are not derived from Design Basis Accident (DBA) analyses.
They are prescribed during normal operation to avoid encountering
pressure, temperature, and temperature rate of change conditions
that might cause undetected flaws to propagate and cause nonductile
failure of the RCPB [reactor coolant pressure boundary], a condition
that is unanalyzed. * * * Since the P/T limits are not derived from
any DBA, there are no acceptance limits related to the P/T limits.
Rather, the P/T limits are acceptance limits themselves since they
preclude operation in an unanalyzed condition.''
The proposed change will not affect any safety limits, limiting
safety system settings, or limiting conditions of operation. The
proposed change does not represent a change in initial conditions,
or in a system response time, or in any other parameter affecting
the course of an accident analysis supporting the Bases of any
Technical Specification. The proposed change does not involve
revision of the P/T limits but rather a revision of the withdrawal
time for the first surveillance capsule. The current P/T limits (and
proposed P/T limits for Power Uprate) were established based on
adjusted reference temperatures for vessel beltline materials
calculated in accordance with Regulatory Position 1 of RG 1.99,
[Revision] 2. P/T limits will continue to be revised as necessary
for changes in adjusted reference temperature due to changes in
fluence according to Regulatory Position 1 until two or more
credible surveillance data sets become available. When two or more
credible surveillance data sets become available, P/T limits will be
revised as prescribed by Regulatory Position 2 of RG 1.99,
[Revision] 2, or other NRC-approved guidance. Therefore, the
proposed changes do not involve a significant reduction in any
margins of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Entergy Gulf States, Inc., and Entergy Operations, Inc., Docket No. 50-
458, River Bend Station, Unit 1, West Feliciana Parish, Louisiana
Date of amendment request: October 29, 1999.
Description of amendment request: The proposed license amendment
would change the River Bend Station (RBS) Updated Safety Analysis
Report (USAR), Sections 6.2 and 15.6, to incorporate a revision to the
calculation of radiological doses following a loss-of-coolant-accident
(LOCA). The LOCA dose calculation was revised as a result of (1) an
increase in the calculated positive pressure period (PPP) to account
for a new phenomenon identified in Information Notice (IN) 88-76, (2) a
more conservative Suppression Pool water volume value, (3) an
additional and more conservative liquid leakage term identified in IN
91-56, and (4) changes to the engineered safety features (ESF) systems
liquid leakage term.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. The proposed changes do not significantly increase the
probability or consequences of an accident previously evaluated.
The analysis changes described by this proposed change to the
USAR are not initiators to events, and therefore do not involve the
probability of an accident. These modifications reflect a revision
to the post-LOCA dose calculation. USAR Section 15.6.5.1.1 states
that ``There are no realistic, identifiable events which would
result in a pipe break inside of containment of the magnitude
required to cause an accident LOCA * * * However, since such an
accident provides an upper limit estimate to the resultant effects
for this category of pipe breaks, it is evaluated without the causes
being identified.'' The analysis itself does not identify an
initiator, nor is it the initiator, of a LOCA. There was no physical
change to the plant. The increase to the positive pressure period
(PPP) was the result of inclusion of phenomena not previously
included in the analysis documented in the SAR [safety analysis
report], and does not have any impact on accident probability. The
inclusion of an NRC [Nuclear Regulatory Commission] Information
Notice (IN) 91-56 unfiltered liquid leakage term is voluntary and
conservative in nature and does not represent an additional failure
that could be construed as an initiator to the event. Therefore,
this change does not increase the probability of occurrence of an
accident evaluated previously in the safety analysis report (SAR).
This proposed change to the USAR does increase the consequences
of an accident, but the increase is not significant. While the
calculated off-site and control room doses of a LOCA did increase in
Revision 1 to the post-LOCA dose calculation (reference 1) [of
Attachment 1 to the License Amendment request, dated October 29,
1999], the dose consequences remain below the regulatory limits of
10 CFR [Part] 100 and 10 CFR [Part] 50, Appendix A, General Design
Criteria (GDC) 19 as approved per NUREG-0989 and License Amendment
98. This change first accounts for the potential effect that
differential temperature has on the PPP assumed in the off-site dose
analysis. It also conservatively includes an additional liquid
leakage term to account for concerns documented in NRC IN 91-56.
Neither of these changes has an appreciable effect on vital area
access doses. Vital area access dose calculations were not revised
since they still conservatively reflect the expected doses discussed
in USAR Section 12.3.2.4. There is no impact on equipment
qualification associated with the proposed change since other gross
conservatisms exist in those calculations (e.g., not crediting
suppression pool scrubbing) compared to the post-LOCA dose
calculations. Reanalysis of the off-site dose calculation
demonstrates that the revised doses are increased only slightly and
remain significantly less than the regulatory
[[Page 70085]]
limits. With the IN 91-56 term excluded, the increases are within
the criteria of less than 10 [percent] of the remaining margin,
which is the criteria to be applied in the revised 10 CFR 50.59 rule
for minimal increases in consequences. With the IN 91-56 term
included, only the 30 day LPZ [low-population zone] thyroid dose
exceeds the ``minimal increase'' criterion. Note the doses
documented in Table 1 [of Attachment 1 to the License Amendment
request, dated October 29, 1999], above, are less than the values
which had been documented in the SAR prior to the implementation and
NRC approval of TS [Technical Specifications] Amendment 98.
Therefore, this change does not significantly increase the
consequences of an accident previously evaluated in the SAR.
2. The proposed changes would not create the possibility of a
new or different kind of accident from any [previously] analyzed.
This change does not represent a physical change to the plant.
It does not involve initiators to any events in the SAR, nor does
the activity create the possibility for any new accidents. Rather,
this change is a result of the evaluation of the most limiting LOCA
which can occur at River Bend. Therefore, this change involves no
new system interactions and does not create the possibility of an
accident of a different type than those presently evaluated in the
SAR.
3. The proposed changes do not involve a significant reduction
in a margin of safety.
The off-site dose consequences are calculated in accordance with
regulatory guidance found in Regulatory Guide 1.3 and the SRP
[Standard Review Plan], consistent with the analyses submitted to
and approved by the NRC in support of Technical Specification
Amendment 98. It is conservatively assumed that 100 [percent] fuel
failure occurs instantaneously upon a recirculation pipe break, thus
2 of the 3 fission product barriers are immediately eliminated.
These assumptions are made without any causes for the failures being
identified. Containment is assumed to leak at its maximum allowable
leakage rate (0.26 [percent] per day) for the duration of the event.
Other leakage terms, such as engineered safety feature (ESF)
leakage, are assumed to be equal to the Technical Specification
limit. Since assumptions are made in accordance with Technical
Specification allowable values and regulatory guidance, this change
does not reduce the margin of safety as defined in the basis for any
RBS Technical Specification.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Date of amendment request: July 29, 1998, as supplemented by
letters dated July 29, October 28, and November 11, 1999.
Description of amendment request: The amendment will revise
Technical Specification 6.9.1.11.1 by replacing the existing reference
to the Asea Brown Boveri-Combustion Engineering, Inc. (ABB CE), small
break loss-of-coolant (SBLOCA) accident emergency core cooling system
(ECCS) performance evaluation model with the revised model described in
the topical report CENPD-137, Supplement 2, P-A, April 1998.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Will operation of the facility in accordance with this
proposed change involve a significant increase in the probability or
consequences of an accident previously evaluated?
Response: No.
The SBLOCA ECCS performance evaluation is conducted to
demonstrate conformance of light water nuclear power reactors to the
ECCS acceptance criteria of 10 CFR 50.46. The proposed change is
associated with an analysis performed using the new Supplement 2
version of the ABB CE SBLOCA Model (S2M). The primary objective of
the analysis using the new model was to determine the impact of a
reduction in High Pressure Safety Injection (HPSI) pump flow rate
due to increased surveillance test measurement uncertainty. NRC
approval of the new S2M model for use in licensing applications of
CE design pressurized water reactors was obtained on December 16,
1997 (Reference 1) [of license amendment request dated July 29,
1998].
A comparison of the Waterford 3 results for the limiting SBLOCA
scenario using the new S2M model against the criteria of 10 CFR
50.46(b) is summarized below:

to="" ensure="" the="" accident="" analysis="" assumptions="" for="" containment="" sump="" ph="" and="" boron="" concentration="" are="" not="" altered="" following="" complete="" melting="" of=""

a="" significant="" reduction="" in="" a="" margin="" of="" safety.="" the="" ice="" condenser="" technical="" specifications="" ensure="" that="" during="" a="" loca="" or="" slb="" the="" ice=""

heat="" energy="" initially="" and="" over="" a="" prescribed="" time="" period="" to="" assist="" in="" precluding="" containment="" vessel="" failure,="" and="" that="" it="" will="" not="" alter="" the="" bulk="" containment="" sump="" ph="" and="" boron="" concentration="" assumed="" in="" the="" accident="" analysis.="" since="" the="" proposed="" changes="" do="" not="" physically="" alter="" the="" ice="" condenser,="" but="" rather="" only="" serve="" to="" strengthen="" and="" clarify="" ice="" sampling="" and="" analysis="" requirements,="" the="" only="" area="" of="" potential="" concern="" is="" the="" effect="" these="" changes="" could="" have="" on="" bulk="" containment="" sump="" ph="" and="" boron="" concentration="" following="" ice="" melt.="" however,="" this="" is="" not="" affected="" because="" there="" is="" no="" change="" in="" the="" existing="" requirements="" for="" ph="" and="" boron="" concentration,="" except="" to="" add="" an="" upper="" limit="" on="" boron="" concentration.="" this="" upper="" limit="" is="" the="" bounding="" value="" for="" the="" hot="" leg="" switchover="" timing="" calculation.="" averaging="" the="" ph=""

Notice of Issuance of Amendments to Facility Operating Licenses and
Final Determination of No Significant Hazards Consideration and
Opportunity for a Hearing (Exigent Public Announcement or Emergency
Circumstances)
During the period since publication of the last biweekly notice,
the Commission has issued the following amendments. The Commission has
determined for each of these amendments that the application for the
amendment complies with the standards and requirements of the Atomic
Energy Act of 1954, as amended (the Act), and the Commission's rules
and regulations. The Commission has made appropriate findings as
required by the Act and the Commission's rules and regulations in 10
CFR Chapter I, which are set forth in the license amendment.
Because of exigent or emergency circumstances associated with the
date the amendment was needed, there was not time for the Commission to
publish, for public comment before issuance, its usual 30-day Notice of
Consideration of Issuance of Amendment, Proposed No Significant Hazards
Consideration Determination, and Opportunity for a Hearing.
For exigent circumstances, the Commission has either issued a
Federal Register notice providing opportunity for public comment or has
used local media to provide notice to the public in the area
surrounding a licensee's facility of the licensee's application and of
the Commission's proposed determination of no significant hazards
consideration. The Commission has provided a reasonable opportunity for
the public to comment, using its best efforts to make available to the
public means of communication for the public to respond quickly, and in
the case of telephone comments, the comments have been recorded or
transcribed as appropriate and the licensee has been informed of the
public comments.
In circumstances where failure to act in a timely way would have
resulted, for example, in derating or shutdown of a nuclear power plant
or in prevention of either resumption of operation or of increase in
power output up to the plant's licensed power level, the Commission may
not have had an opportunity to provide for public comment on its no
significant hazards consideration determination. In such case, the
license amendment has been issued without opportunity for comment. If
there has been some time for public comment but less than 30 days, the
Commission may provide an
[[Page 70097]]
opportunity for public comment. If comments have been requested, it is
so stated. In either event, the State has been consulted by telephone
whenever possible.
Under its regulations, the Commission may issue and make an
amendment immediately effective, notwithstanding the pendency before it
of a request for a hearing from any person, in advance of the holding
and completion of any required hearing, where it has determined that no
significant hazards consideration is involved.
The Commission has applied the standards of 10 CFR 50.92 and has
made a final determination that the amendment involves no significant
hazards consideration. The basis for this determination is contained in
the documents related to this action. Accordingly, the amendments have
been issued and made effective as indicated.
Unless otherwise indicated, the Commission has determined that
these amendments satisfy the criteria for categorical exclusion in
accordance with 10 CFR 51.22. Therefore, pursuant to 10 CFR 51.22(b),
no environmental impact statement or environmental assessment need be
prepared for these amendments. If the Commission has prepared an
environmental assessment under the special circumstances provision in
10 CFR 51.12(b) and has made a determination based on that assessment,
it is so indicated.
For further details with respect to the action see (1) the
application for amendment, (2) the amendment to Facility Operating
License, and (3) the Commission's related letter, Safety Evaluation
and/or Environmental Assessment, as indicated. All of these items are
available for public inspection at the Commission's Public Document
Room, the Gelman Building, 2120 L Street, NW., Washington, DC, and
electronically from the ADAMS Public Library component on the NRC Web
site, http://www.nrc.gov (the Electronic Reading Room).
The Commission is also offering an opportunity for a hearing with
respect to the issuance of the amendment. By January 14, 1999, the
licensee may file a request for a hearing with respect to issuance of
the amendment to the subject facility operating license and any person
whose interest may be affected by this proceeding and who wishes to
participate as a party in the proceeding must file a written request
for a hearing and a petition for leave to intervene. Requests for a
hearing and a petition for leave to intervene shall be filed in
accordance with the Commission's ``Rules of Practice for Domestic
Licensing Proceedings'' in 10 CFR Part 2. Interested persons should
consult a current copy of 10 CFR 2.714 which is available at the
Commission's Public Document Room, the Gelman Building, 2120 L Street,
NW., Washington, DC and electronically from the ADAMS Public Library
component on the NRC Web site, http://www.nrc.gov (the Electronic
Reading Room). If a request for a hearing or petition for leave to
intervene is filed by the above date, the Commission or an Atomic
Safety and Licensing Board, designated by the Commission or by the
Chairman of the Atomic Safety and Licensing Board Panel, will rule on
the request and/or petition; and the Secretary or the designated Atomic
Safety and Licensing Board will issue a notice of a hearing or an
appropriate order.
As required by 10 CFR 2.714, a petition for leave to intervene
shall set forth with particularity the interest of the petitioner in
the proceeding, and how that interest may be affected by the results of
the proceeding. The petition should specifically explain the reasons
why intervention should be permitted with particular reference to the
following factors: (1) The nature of the petitioner's right under the
Act to be made a party to the proceeding; (2) the nature and extent of
the petitioner's property, financial, or other interest in the
proceeding; and (3) the possible effect of any order which may be
entered in the proceeding on the petitioner's interest. The petition
should also identify the specific aspect(s) of the subject matter of
the proceeding as to which petitioner wishes to intervene. Any person
who has filed a petition for leave to intervene or who has been
admitted as a party may amend the petition without requesting leave of
the Board up to 15 days prior to the first prehearing conference
scheduled in the proceeding, but such an amended petition must satisfy
the specificity requirements described above.
Not later than 15 days prior to the first prehearing conference
scheduled in the proceeding, a petitioner shall file a supplement to
the petition to intervene which must include a list of the contentions
which are sought to be litigated in the matter. Each contention must
consist of a specific statement of the issue of law or fact to be
raised or controverted. In addition, the petitioner shall provide a
brief explanation of the bases of the contention and a concise
statement of the alleged facts or expert opinion which support the
contention and on which the petitioner intends to rely in proving the
contention at the hearing. The petitioner must also provide references
to those specific sources and documents of which the petitioner is
aware and on which the petitioner intends to rely to establish those
facts or expert opinion. Petitioner must provide sufficient information
to show that a genuine dispute exists with the applicant on a material
issue of law or fact. Contentions shall be limited to matters within
the scope of the amendment under consideration. The contention must be
one which, if proven, would entitle the petitioner to relief. A
petitioner who fails to file such a supplement which satisfies these
requirements with respect to at least one contention will not be
permitted to participate as a party.
Those permitted to intervene become parties to the proceeding,
subject to any limitations in the order granting leave to intervene,
and have the opportunity to participate fully in the conduct of the
hearing, including the opportunity to present evidence and cross-
examine witnesses. Since the Commission has made a final determination
that the amendment involves no significant hazards consideration, if a
hearing is requested, it will not stay the effectiveness of the
amendment. Any hearing held would take place while the amendment is in
effect.
A request for a hearing or a petition for leave to intervene must
be filed with the Secretary of the Commission, U.S. Nuclear Regulatory
Commission, Washington, DC 20555-0001, Attention: Rulemakings and
Adjudications Staff or may be delivered to the Commission's Public
Document Room, the Gelman Building, 2120 L Street, NW, Washington, DC,
by the above date. A copy of the petition should also be sent to the
Office of the General Counsel, U.S. Nuclear Regulatory Commission,
Washington, DC 20555-0001, and to the attorney for the licensee.
Nontimely filings of petitions for leave to intervene, amended
petitions, supplemental petitions and/or requests for a hearing will
not be entertained absent a determination by the Commission, the
presiding officer or the Atomic Safety and Licensing Board that the
petition and/or request should be granted based upon a balancing of the
factors specified in 10 CFR 2.714(a)(1) (i)-(v) and 2.714(d).
