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 May 26, 1995, through June 9, 1995. The last
biweekly notice was published on Tuesday, June 6, 1995 (60 FR 29869).
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 Rules Review and
Directives Branch, Division of Freedom of Information and Publications
Services, Office of Administration, U.S. Nuclear Regulatory Commission,
Washington, DC 20555, 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 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 July 21, 1995, 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 at the local public
document room for the particular facility involved. 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 [[Page 32360]] 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, 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, 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).
For further details with respect to this action, see the
application for amendment which is available for public inspection at
the Commission's Public Document Room, the Gelman Building, 2120 L
Street, NW., Washington, DC, and at the local public document room for
the particular facility involved.
Commonwealth Edison Company, Docket Nos. STN 50-456 and STN 50-457,
Braidwood Station, Unit Nos. 1 and 2, Will County, Illinois
Date of amendment request: June 8, 1995, supersedes December 16,
1994, request in its entirety, supplemented by letters dated November
30, 1994, April 27, 1995, May 5 and May 11, 1995.
Description of amendment request: The proposed amendment would
revise Figure 3.4-4a in the Braidwood Unit 1's technical specifications
which provides the nominal pressurizer power operated relief valve set
points for the low-temperature overpressure protection system (LTOPS).
The proposed revision would extend the applicability of Figure 3.4-4a
from 5.37 effective full power years (EFPY) to 16 EFPY (Unit 1). In
addition, the proposed amendment removes the 638 psig administrative
limit line from the LTOPS curve, because the appropriate instrument
uncertainties and discharge piping pressure limits are included in the
proposed LTOPS curve. The amendment request also proposes
administrative changes to Figure 3.4-4a format and its associated index
page.
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.
The new LTOPS curve will not change any postulated accident
scenarios. The revised curve was developed using industry standards
and regulations which are recognized as being inherently
conservative. Appropriate instrument uncertainties and allowances
have been included in the development of the LTOPS curves. The PT
and LTOPS curves provide RCS pressure limits to protect the Reactor
Pressure Vessel (RPV) from brittle fracture by clearly separating
the region of normal operations from the region where the RPV is
subject to brittle fracture.
Using Regulatory Guide (RG) 1.99, ``Radiation Embrittlement of
Reactor Vessel Materials,'' Revision 2, Braidwood Unit 1
Surveillance Capsule U and Capsule X results and the requirements of
Appendix G to 10 CFR 50, as modified by the guidance in ASME Code
Case N-514, a new LTOPS curve was prepared. This new curve, in
conjunction with the PT Limit curves, and the heatup and cooldown
ranges provides the required assurance that the RPV is protected
from brittle fracture.
No changes to the design of the facility have been made, no new
equipment has been installed, and no existing equipment has been
removed or modified. This amendment will not change any system
operating modes. The revised LTOPS curve provides assurance that the
RPV is protected from brittle fracture.
The index page and format changes are purely administrative in
nature and are designed to reflect the change in the duration of
applicability of Figure 3.4-4a and improve the readability of Figure
3.4-4a. These administrative changes will have no effect on any
equipment, system, or operating mode.
Thus, the proposed change does 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 use of the new LTOPS curve does not change any postulated
accident scenarios. The new LTOPS curve was generated using
Braidwood capsule surveillance data and an approved, conservative
methodology. No new equipment will be installed, and no existing
equipment will be modified. No new system interfaces are created,
and no existing system interfaces are modified. The new LTOPS curve
provides assurance that the RPV is protected from brittle fracture.
No new accident or malfunction mechanism is introduced by this
amendment.
The index page and format changes are purely administrative in
nature and are designed to reflect the change in the duration of
applicability of Figure 3.4-4a, and improve the readability of
Figure 3.4-4a. These administrative changes will have no effect on
any equipment, system, or operating mode.
Therefore, the proposed change does 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 new LTOPS curve was developed using industry standards and
regulations which are recognized as being inherently conservative.
Appropriate instrument uncertainties and allowances are included in
the development of the new LTOPS curve. This amendment will not
change the operational characteristics or design of any equipment or
system.
All accident analysis assumptions and conditions will continue
to be met. The RPV is adequately protected from non-ductile failure
by the revised LTOPS curve.
The index page and format changes are purely administrative in
nature and are designed to reflect the change in the duration of
applicability of Figure 3.4-4a, and improve the readability of
Figure 3.4-4a. These administrative changes will have no effect on
any equipment, system, or operating mode.
Thus, 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 [[Page 32361]] 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.

Charlevoix County, Michigan
Date of amendment request: March 4, 1993, as revised April 14,
1993, as supplemented April 19 and May 31, 1995
Description of amendment request: The proposed amendment would
revise the Technical Specifications (TS) to conform to the wording of
the revised 10 CFR Part 20, ``Standards for Protection Against
Radiation,'' and to reflect a separation of chemistry and radiation
protection responsibilities. The supplemental submittals provided
additional information on the proposed TS change in response to NRC's
request for additional information of May 5, 1995. The original
submittal was noticed on May 12, 1993 (58 FR 28053), as corrected June
1, 1993 (58 FR 31222).
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 the proposed change involve a significant increase in the
probability or consequences of an accident previously evaluated?
The proposed change does not affect the probability or
consequences of an accident. The proposed change is to the
ADMINISTRATIVE and RADIOLOGICAL EFFLUENT RELEASES sections of the
facility Technical Specifications, and are administrative in nature.
- Change ``Chemistry and Radiation Protection Supervisor'' to
``Radiation Protection Supervisor.''
- The change from ``mR/h'' to ``mrem/h'' is solely a change in
terminology since the revised 10 CFR 20 does not recognize or define
the roentgen as a unit of radiation.
- The Liquid Effluents Concentration section and the associated
bases have been revised to conform with 10 CFR 50.36(a) [10 CFR
50.36a] with effluent concentrations limited to 10 times the limits
of 10 CFR 20.1001 - 20.2402, Appendix B, Table 2, Column 2.
- The actual instantaneous dose rate limits of the Gaseous
Effluents Dose Rate section have not changed. However, the bases
section has. Under the former 10 CFR 20, these dose rates correspond
roughly to maximum permissible concentration and dose(s) received by
the maximum exposed member of the public if allowed to continue for
an entire year. These limits are used more as instantaneous limits
(dose rates above which are not allowed to continue for more than
one hour at a time) so as to provide assurance not to exceed 10 CFR
50, Appendix I limits.
2. Will the proposed change(s) create the possibility of a new
or different kind of accident from any accident previously
evaluated?
This proposed change is required by the implementation of a new
10 CFR Part 20 requirements (except for the title change) and are
administrative in nature (sic). Neither the material condition of
the facility nor the accident analyses are affected by this proposed
change. Therefore, the proposed change does not create the
possibility of a different type of accident than previously
evaluated.
3. Will the proposed change involve a significant reduction in
the margin of safety?
Each limit that was affected increased the margin of safety by
making the limit more conservative; or remained the same.
- The change of distance to ``30 centimeters'' (12 inches) is
more conservative, providing a higher degree of protection for
occupationally exposed worker.
- The liquid effluent concentration limits remain essentially
the same. The bases have changed to [10 CFR 50.36a] reflect 10 times
10 CFR 20.1001 - 20.2402, Appendix B, Table 2, Column 2 limits as
controlled by 10 CFR 50.36(a) [10 CFR 50.36a] dose limits.
- Effluent alarm setpoints were reviewed to determine any
necessary changes and were found to be set appropriately. No change
will be necessary.
- ``The instantaneous release rate limits for airborne releases
will not be changed because they are imposed on licensees as a
control to ensure that the licensees meet Appendix I requirements.''
Alarm setpoints for these dose rate limits may change slightly due
to changes in scientific data and will be reviewed and changed as
appropriate prior to implementation.
Therefore, the proposed change does not involve 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
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Duke Power Company, et al., Docket Nos. 50-413 and 50-414, Catawba
Nuclear Station, Units 1 and 2, York County, South Carolina
Date of amendment request: April 12, 1995
Description of amendment request: The amendments delete Technical
Specification 3/4.3.4, ``Turbine Overspeed Protection,'' and its
associated Bases. The deletion of TS 3/4.3.4 and its associated Bases
provides Duke Power Company the flexibility to implement the
manufacturer's recommendations for turbine steam valve surveillance
test requirements. These test requirements will be relocated from the
TS to the Selected Licensee Commitments (SLC) Manual. The SLC Manual is
Chapter 16 of the Updated Final Safety Analysis Report.
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:
Criterion 1
The requested amendments will not involve a significant increase
in the probability or consequences of an accident previously
evaluated. Relocation of the affected TS section to the SLC Manual
will have no effect on the probability of any accident occurring. In
addition, the consequences of an accident will not be impacted since
the above system will continue to be utilized in the same manner as
before. No impact on the plant response to accidents will be
created.
Criterion 2
The requested amendments will not create the possibility of a
new or different kind of accident from any accident previously
evaluated. No new accident causal mechanisms will be created as a
result of relocating the affected TS requirements to the SLC Manual.
Plant operation will not be affected by the proposed amendments and
no new failure modes will be created.
Criterion 3
The requested amendments will not involve a significant
reduction in a margin of safety. No impact upon any plant safety
margins will be created. Relocation of the affected TS requirements
to the SLC Manual in consistent with the content of the Westinghouse
RSTS [Revised Standard Technical Specifications], as the NRC did not
require technical specification controls for the turbine overspeed
protection system in the RSTS. The proposed amendments are
consistent with the NRC philosophy of encouraging utilities to
propose amendments that are consistent with the content of the RSTS.
Based upon the preceding analyses, Duke Power Company concludes
that the requested amendments do not involve a significant hazards
consideration.
The NRC staff has reviewed the licensee's analysis and, based on
this [[Page 32362]] review, it appears that the three standards of 10
CFR 50.92(c) are satisfied. Therefore, the NRC staff proposes to

Duke Power Company, et al., Docket Nos. 50-413 and 50-414, Catawba
Nuclear Station, Units 1 and 2, York County, South Carolina
Date of amendment request: May 18, 1995, as supplemented by letter
dated May 31, 1995.
Description of amendment request: The proposed amendment would
change Tecnical Specification (TS) 3.6.1.2 to defer the next scheduled
containment integrated leak rate test (ILRT) at Catawba, Unit 2, for
one outage, from the end-of-cycle (EOC) 7 refueling outage (scheduled
for October 1995) to EOC-8 (scheduled for March 1997). Title 10 of the
Code of Federal Regulations, Part 50, Appendix J, requires that three
ILRTs be performed at approximately equal intervals during each 10-year
service period at a nuclear station. ``Approximately equal intervals''
is defined in Catawba's TS as 40 plus or minus 10 months. The proposed
one-time change would allow Catawba to extend that interval to less
than or equal to 70 months.
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 will not involve a significant increase
in the probability or consequences of an accident previously
evaluated.
Containment leak rate testing is not an initiator of any
accident; the proposed interval extension does not affect reactor
operations or accident analysis, and has no perceptible radiological
consequences. Therefore, this proposed change will not involve a
significant increase in the probability or consequences of any
previously[]evaluated accident.
2. The proposed change will not create the possibility of any
new accident not previously evaluated.
The proposed change does not affect normal plant operations or
configuration, nor does it affect leak rate test methods. The test
history at Catawba (no ILRT [intergrated leak rate test] failures)
provides continued assurance of the leak tightness of the
containment structure.
3. There is no significant reduction in a margin of safety.
It has been documented in draft NUREG-1493 that an increase in
the ILRT interval from 1 test every 3 years to 1 test every 10 years
would result in an increase in population exposure risk in the
vicinity of 5 representative plants from .02% to .14%. The proposed
change included herein, an increase from 40 [plus or minus] 10
months to [less than or equal to] 70 months, represents a small
fraction of that already very small increase in risk. Therefore, it
may be concluded that no significant reduction in a margin of safety
will occur.
Based on the above, no significant hazards consideration is
created by the proposed change.
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.

Florida Power and Light Company, et al., Docket No. 50-335, St.
Lucie Plant, Unit No. 1, St. Lucie County, Florida
Date of amendment request: May 17, 1995
Description of amendment request: The amendment will extend the
applicability of the current Reactor Coolant System (RCS) Pressure/
Temperature Limits and maximum allowed RCS heatup and cooldown rates to
23.6 Effective Full Power Years (EFPY) of operation. In addition,
administrative changes are proposed for [[Page 32363]] TS 3.1.2.1
(Boration Systems Flow Paths-Shutdown) and TS 3.1.2.3 (Charging Pump-
Shutdown) to clarify the conditions for which a High Pressure Safety
Injection pump may be used.
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:
Pursuant to 10 CFR 50.92, a determination may be made that a
proposed license amendment involves no significant hazards
consideration if 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. Each standard is discussed as
follows:
(1) Operation of the facility in accordance with the proposed
amendment would not involve a significant increase in the
probability or consequences of an accident previously evaluated.
The pressure-temperature (P/T) limit curves in the Technical
Specifications are conservatively generated in accordance with the
fracture toughness requirements of 10 CFR 50 Appendix G as
supplemented by the ASME Code Section XI, Appendix G
recommendations. The RTNDT values are based on Regulatory Guide
1.99, Revision 2, shift prediction and attenuation formula. Analyses
of reactor vessel material irradiation surveillance specimens are
used to verify the validity of the fluence predictions and the P/T
limit curves. Use of these curves in conjunction with the
surveillance specimen program ensures that the reactor coolant
pressure boundary will behave in a non-brittle manner and that the
possibility of rapidly propagating fracture is minimized. Based on
the use of plant specific material data, analysis has demonstrated
that the current P/T limit curves will remain conservative for up to
23.6 EFPY.
In conjunction with extending the applicability of the existing
P/T limit curves, the low temperature overpressure protection (LTOP)
analysis for 15 EFPY is also extended. The LTOP analysis confirms
that the current setpoints for the power-operated relief valves
(PORVs) will provide the appropriate overpressure protection at low
Reactor Coolant System (RCS) temperatures. Because the P/T limit
curves have not changed, the existing LTOP values have not changed,
which include the PORV setpoints, heatup and cooldown rates, and
disabling of non-essential components.
The proposed amendment does not change the configuration or
operation of the plant, and assurance is provided that reactor
vessel integrity will be maintained. Therefore, operation of the
facility in accordance with the proposed amendment will not involve
a significant increase in the probability or consequences of an
accident previously evaluated.
(2) Operation of the facility in accordance with the proposed
amendment would not create the possibility of a new or different
kind of accident from any accident previously evaluated.
By applying plant specific data in the determination of critical
vessel material limits, the applicability of the existing pressure
temperature limits and LTOP requirements can be extended. There is
no change in the configuration or operation of the facility as a
result of the proposed amendment. The amendment does not involve the
addition of new equipment or the modification of existing equipment,
nor does it alter the design of St. Lucie plant systems. Therefore,
operation of the facility in accordance with the proposed amendment
would not create the possibility of a new or different kind of
accident from any accident previously evaluated.
(3) Operation of the facility in accordance with the proposed
amendment would not involve a significant reduction in a margin of
safety.
Analysis has demonstrated that the fracture toughness
requirements of 10 CFR 50 Appendix G are satisfied and that
conservative operating restrictions are maintained for the purpose
of low temperature overpressure protection. The P/T limit curves
will provide assurance that the RCS pressure boundary will behave in
a ductile manner and that the probability of a rapidly propagating
fracture is minimized. Therefore, operation of the facility in
accordance with the proposed amendment would not involve a
significant reduction in a margin of safety.
Based on the discussion presented above and on the supporting
Evaluation of Proposed TS Changes, FPL has concluded that this
proposed license amendment involves no significant hazards
consideration.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

389, St. Lucie Plant, Unit Nos. 1 and 2, St. Lucie County, Florida
Date of amendment request: May 17, 1995
Description of amendment request: The proposed amendments will
improve consistency between the Technical Specifications and the
improved Combustion Engineering Standard Technical Specifications
(NUREG-1432, dated September 1992) by incorporating changes in text and
resolving other inconsistencies identified by the NRC and plant
operations staff.
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:
Pursuant to 10 CFR 50.92, a determination may be made that a
proposed license amendment involves no significant hazards
consideration if 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. Each standard is discussed as
follows:
(1) Operation of the facility in accordance with the proposed
amendment would not involve a significant increase in the
probability or consequences of an accident previously evaluated.
The proposed amendments consist of administrative changes to the
Technical Specifications (TS) for St. Lucie Units 1 and 2. The
amendments will implement changes in text to improve consistency
within the TS for each unit, the improved Combustion Engineering
Standard Technical Specifications (NUREG-1432, dated September
1992), and the regulations. The proposed amendments do not involve
changes to the configuration or method of operation of plant
equipment that is used to mitigate the consequences of an accident,
nor do the changes otherwise affect the initial conditions or
conservatism assumed in any of the plant accident analyses.
Therefore, operation of the facility in accordance with the proposed
amendments would not involve a significant increase in the
probability or consequences of an accident previously evaluated.
(2) Operation of the facility in accordance with the proposed
amendment would not create the possibility of a new or different
kind of accident from any accident previously evaluated.
The proposed administrative revisions will not change the
physical plant or the modes of plant operation defined in the
Facility License for each unit. The changes do not involve the
addition or modification of equipment nor do they alter the design
or operation of plant systems. Therefore, operation of the facility
in accordance with the proposed amendments would not create the
possibility of a new or different kind of accident from any accident
previously evaluated.
(3) Operation of the facility in accordance with the proposed
amendment would not [[Page 32364]] involve a significant reduction
in a margin of safety.
The proposed amendments are administrative in nature and do not
change the basis for any technical specification that is related to
the establishment of, or the preservation of, a nuclear safety
margin. Therefore, operation of the facility in accordance with the
proposed amendments would not involve a significant reduction in a
margin of safety.
Based on the above discussion and the supporting Evaluation of
Technical Specification changes, FPL has determined that the
proposed license amendment involves no significant hazards
consideration.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Turkey Point Plant Units 3 and 4, Dade County, Florida
Date of amendment request: May 23, 1995
Description of amendment request: The licensee proposes to change
Turkey Point Units 3 and 4 Technical Specifications (TS) by changing
the setpoint presentation format for the Reactor Protection System
(RPS) and Engineered Safety Features Actuation System (ESFAS)
instrumentation setpoints contained in Technical Specification Tables
2.2-1 and 3.3-3. The approved Westinghouse five-column instrument
setpoint methodology currently being used to establishing those
setpoints would be retained. The intent of the amendments is to
eliminate the need for minor administrative license amendments to these
tables that do not impact either the Trip Setpoints or the Safety
Analysis Limits.
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) Operation of the facility in accordance with the proposed
amendments would not involve a significant increase in the
probability or consequences of an accident previously evaluated.
No changes to the Reactor Trip System instrumentation setpoints,
ESFAS instrumentation setpoints, or the Turkey Point Plant licensing
basis (NRC-approved, Westinghouse five-column setpoint methodology,
as documented in Westinghouse topical report WCAP-12745P), is being
made. The changes proposed reduce the level of detail in the
Technical Specifications and place that detailed information in
controlled procedures, drawings and the Final Safety Analysis
Report. Since the setpoints and methodology remain the same, the
changes proposed by this submittal will not increase the probability
or consequences of an accident previously evaluated.
(2) Operation of the facility in accordance with the proposed
amendments would not create the possibility of a new or different
kind of accident from any accident previously evaluated.
These proposed changes remove from the Technical Specifications
a level of detail which will be maintained in controlled procedures
and drawings. The Turkey Point Plant licensing basis (NRC-approved,
Westinghouse five column setpoint methodology, as documented in
Westinghouse topical report WCAP-12745P), continues to be used to
calculate the Reactor Trip System and ESFAS setpoints. No changes to
Reactor Trip System or ESFAS instrumentation setpoints are proposed.
Since the same methodology will be used to determine the setpoints
and no setpoints are changed, the possibility that a new or
different kind of accident from any previously evaluated will not be
created.
(3) Operation of the facility in accordance with the proposed
amendments would not involve a significant reduction in a margin of
safety.
The Turkey Point Plant licensing basis (NRC-approved,
Westinghouse five column setpoint methodology, as documented in
Westinghouse topical report WCAP-12745P), continues to be used to
calculate the Reactor Trip System and ESFAS setpoints. No changes to
the Reactor Trip System or ESFAS instrumentation setpoints are
proposed. Since the same methodology will be used to determine the
setpoints, and no setpoints are changed by this submittal, this
change does not involve a 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 50.92(c) are
satisfied.Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

50-321 and 50-366, Edwin I. Hatch Nuclear Plant, Units 1 and 2,
Appling County, Georgia
Date of amendment request: June 6, 1995
Description of amendment request: The proposed change would revise
Plant Hatch Units 1 and 2 Technical Specification (TS) Surveillance
Requirements (SR) 3.6.4.1.3 and 3.6.4.1.4 for the secondary containment
drawdown. The revision would reduce the SR acceptance criteria to
greater than or equal to 0.20 inch of vacuum from greater than or equal
to 0.25 inch of vacuum. Also, the licensee proposed to change the Bases
to reflect the proposed TS revision.
The licensee stated that the secondary containment performs no
active function in response to either loss-of-coolant accident or fuel
handling accident. However, its leak tightness is required to ensure
that the release of radioactive materials from the primary containment
is restricted to those leakage paths and associated leakage rates
assumed in the accident analysis and that fission products entrapped
within the secondary containment structure will be treated by the Unit
1 and Unit 2 standby gas treatment systems prior to discharge to the
environment. This change will continue to provide adequate margin for
the secondary containment to be sufficiently leak tight such that the
conclusions of the accident analysis remain valid.
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 change does not involve a significant increase in the
probability or consequences of an accident previously evaluated. The
secondary containment serves a mitigation function and therefore
this change does not increase the probability of an accident
previously evaluated. The consequences of the previously evaluated
accidents are not affected because at the wind conditions assumed in
the accident analysis the building will be at a negative pressure
and no exfiltration is postulated. Furthermore, the estimated wind
speed at which exfiltration might take place (31 mph) is not a
frequent occurrence (wind speeds of greater than 24 mph occur [less
than] <0.5% of="" the="" time="" based="" on="" plant="" hatch="" specific="" meteorological="" data).="" 2.="" the="" proposed="" change="" does="" not="" create="" the="" possibility="" of="" a="" new="" or="" different="" kind="" of="" accident="" from="" any="" accident="" previously="" analyzed.="" revising="" the="" surveillance="" [[page="" 32365]]="" requirement="" acceptance="" criteria="" does="" not="" physically="" modify="" the="" plant="" nor="" does="" it="" modify="" the="" operation="" of="" any="" existing="" equipment.="" 3.="" the="" proposed="" change="" does="" not="" involve="" a="" significant="" reduction="" in="" the="" margin="" of="" safety.="" the="" change="" in="" vacuum="" acceptance="" criteria="" results="" in="" a="" slightly="" lower="" wind="" speed="" that="" may="" result="" in="" exfiltration="" from="" the="" building.="" however,="" this="" wind="" speed="" (31="" mph)="" is="" in="" the="" realm="" of="" wind="" speeds="" which="" are="" infrequent="" at="" plant="" hatch.="" furthermore,="" there="" are="" numerous="" conservatisms="" in="" the="" existing="" dose="" calculations="" including:="" neutral="" to="" stable="" meteorological="" conditions,="" ground="" level="" release="" until="" establishment="" of="" the="" required="" vacuum,="" accident="" source="" terms="" at="" event="" initiation,="" and="" no="" credit="" for="" plateout.="" the="" secondary="" containment="" would="" be="" maintained="" at="" a="" slight="" negative="" pressure="" shortly="" after="" the="" standby="" gas="" treatment=""

This is a ``margin'' over and above the boltup temperature required
by Appendix G to the 1992 ASME Section XI Code, since Appendix G
would allow a boltup temperature of 48F.
The above proposed changes to the Limiting Condition for
Operation for tensioning the reactor vessel head studs do not alter
the configuration, normal operation, design bases, function,
mission, or performance of the subject components. Therefore, the
proposed changes do not affect the margin of safety inherent in the
design, analysis, function, or operation of the reactor vessel head
flange region. The proposed changes do not alter the fuel clad
barrier, fuel integrity, reactor vessel integrity, reactor coolant
system integrity, or the containment boundary integrity; thus the
margin of safety related to these barriers remains unchanged.
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.

Northeast Nuclear Energy Company (NNECO), Docket No. 50-245,
Millstone Nuclear Power Station, Unit 1, New London County,
Connecticut
Date of amendment request: May 24, 1995
Description of amendment request: The proposed amendment would
permit an individual who does not have a current senior reactor
operator (SRO) license to hold the Operations Manager position. The
position will require the individual to have previously held an SRO
license at a boiling water reactor (BWR). An individual serving in the
capacity of the Assistant Operations Manager will hold a current SRO
license for Millstone Unit 1, if the Operations Manager does not. In
addition, the proposed amendment would renumber the applicable sections
of the related technical specifications.
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:
NNECO has reviewed the proposed change in accordance with
10CFR50.92 and concluded that the change does not involve a
significant hazards consideration (SHC). The basis for this
conclusion is that the three criteria of 10CFR50.92(c) are not
compromised. The proposed change does not involve an SHC because the
changes would not:
1. Involve a significant increase in the probability or
consequences of an accident previously analyzed.
The proposed change affects an administrative control, which was
based on the guidance of ANSI N18.1-1971. ANSI N18.1-1971
recommended that the Operations Manager hold an SRO license. The
current guidance in Section 4.2.2 of ANSI/ANS 3.1-1987 recommends,
as one option, that the Operations Manager have held a license for a
similar unit and the Operations Middle Manager hold an SRO license.
While the Operations Middle Manager position does not exist at
Millstone Unit No. 1, NNECO has created the position of Assistant
Operations Manager. The individual in this position would meet the
requirements for, and would have responsibilities as recommended in,
ANSI/ANS 3.1-1987 for the Operations Middle Manager position.
Therefore, the proposed change requests an exception to ANSI
N18.1-1971 to allow use of ANSI/ANS 3.1-1987 in a limited
circumstance. Specifically, the proposed revision to Technical
Specification 6.3.1 would require the Operations Manager to either
hold an SRO license at Millstone Unit No. 1 or have held an SRO at a
BWR.
If the Operations Manager does not hold an SRO license at
Millstone Unit No. 1, the specification will require the Assistant
Operations Manager to hold, and continue to hold, an SRO license.
The proposed change includes the requirement to have held a license
for a similar unit (a BWR) in accordance with Section 4.2.2 of ANSI/
ANS 3.1-1987, if the Operations Manager does not hold an SRO license
at Millstone Unit No. 1. For those areas of knowledge that require
an SRO license, the Assistant Operations Manager will provide the
technical guidance typically provided by the Operations Manager.
The proposed change does not alter the design of any system,
structure, or component, nor does it change the way plant systems
are operated. It does not reduce the knowledge, qualifications, or
skills of licensed operators, and does not affect the way the
Operations Department is managed by the Operations Manager. The
Operations Manager will continue to maintain the effective
performance of his personnel and ensure the plant is operated safely
and in accordance with the requirements of the operating license.
Additionally, the control room operators will continue to be
supervised by the licensed Shift Supervisor.
The proposed change does not detract from the Operations
Manager's ability to perform his primary responsibilities. In this
case, by having previously held an SRO license, the Operations
Manager has achieved the necessary training, skills, and experience
to fully understand the operation of plant equipment and the watch
requirements for operators. In summary, the proposed change does not
affect the ability of the Operations Manager to provide the plant
oversight required of that position. Thus, it does not involve a
significant increase in the probability or consequences of an
accident previously evaluated.
2. Create the possibility of a new or different kind of accident
from any previously analyzed.
The proposed change to Technical Specification 6.3.1 does not
affect the design or function of any plant system, structure, or
component, nor does it change the way plant systems are operated. It
does not affect the performance of licensed operators. Operation of
the plant in conformance with technical specifications and other
license requirements will continue to be supervised by personnel who
hold an SRO license. The proposed change to Technical Specification
6.3.1 ensures that the Operation Manager will be a knowledgeable and
qualified individual by requiring the individual to have held an SRO
license at a BWR. Based on the above, the proposed change does not
create the possibility of a new or different kind of accident from
any previously evaluated.
3. Involve a significant reduction in the margin of safety.
The proposed change involves an administrative control that is
not related to the margin of safety. The proposed change does not
reduce the level of knowledge or experience required of an
individual who fills the Operations Manager position, nor does it
affect the conservative manner in which the plant is operated. The
Control Room operators will continue to be supervised by personnel
who hold an SRO license. Thus, 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
[[Page 32371]] amendment request involves no significant hazards
consideration.

Northeast Nuclear Energy Company (NNECO), Docket No. 50-245,
Millstone Nuclear Power Station, Unit 1, New London County,
Connecticut
Date of amendment request: May 26, 1995
Description of amendment request: The proposed amendment will
delete the old limiting conditions for operation (LCOs) and
surveillance requirements and add new LCOs, surveillance requirements,
and bases for the loss of normal power (LNP) instrumentation system.
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:
NNECO has reviewed this proposed change in accordance with
10CFR50.92 and concluded that this change does not involve a
significant hazards consideration (SHC). The basis for this
conclusion is that the three criteria of 10CFR50.92(c) are not
compromised. The proposed change does not involve an SHC because the
changes would not:
1. Involve a significant increase in the probability or
consequences of an accident previously analyzed.
The change does not increase the probability of a loss of off-
site power event or the occurrence of any accidents which assume
loss of off-site power. This is ensured by the LNP instrumentation
system design which uses multiple sensing relays, redundancy, and
qualified Class 1E components, as well as conservative operability
and surveillance requirements.
Full LNP logic requires two sets of relays to trip in one of two
redundant groups. One set monitors bus 14E and the other set
monitors bus 14F. Separate sets are provided for loss of voltage and
degraded voltage monitoring. This design minimizes the likelihood of
an inadvertent full LNP initiation. To maintain redundancy in the
instrumentation, two separate groups are provided, each group being
powered from an independent DC supply. Partial LNP logic is also
provided to detect a loss of voltage on a single emergency bus.
Redundancy in the partial LNP logic is achieved by providing an
independent logic for each emergency power train.
The proposed technical specification would require that the LNP
instrumentation be maintained operable except when the unit is in
cold shutdown or refueling conditions. If redundancy in the ability
to detect a loss of voltage or degraded voltage and initiate a full
LNP is not maintained, reactor operation would be permitted for
seven days. In this situation, both full and partial LNP (and both
emergency power sources) remain operable. An action statement of
seven days, which is the same as the action statement duration for
an inoperable EDG [emergency diesel generator], is justified based
on continued operability of the other LNP group. Additionally, it
allows a reasonable amount of time to perform repairs.
The time delays and voltage setpoints specified in Table 3.2.4
ensure that the emergency power source starting and loading times
continue to meet the current technical specification requirements.
Also, these time delays are long enough to preclude false trips due
to anticipated voltage transients (e.g., during motor starts). The
relay calibration surveillance procedure will establish acceptance
criteria for each relay to ensure that the total times specified in
Table 3.2.4 are not exceeded. The proposed surveillance testing and
calibration frequency of every refueling outage is consistent with
the requirements in the current technical specification.
2. Create the possibility of a new or different kind of accident
from any previously evaluated.
There are no new failure modes associated with this change since
the proposed requirements will ensure the LNP instrumentation system
is available to perform its safety function. Individual voltage
sensing relays, when removed from their cases, would provide the
tripped contact configuration. The proposed technical specification
would allow relays to be placed in the tripped condition as long as
it would not inhibit the LNP function or cause an inadvertent
initiation. Additionally, since the design function to ensure that
adequate power is available to operate the emergency safeguards
equipment has not changed, no new accident or accident of a
different kind is created.
3. Involve a significant reduction in the margin of safety.
The protective boundaries are not affected because the
consequences of any design basis accident are not changed. Since the
protective boundaries are not affected, the safety limits are also
unaffected. The proposed change maintains the basis of the technical
specifications by ensuring that adequate electrical power is
available to operate the emergency safeguards equipment. By
maximizing the operability of the LNP instrumentation without
requiring high risk testing, the proposed change will improve the
margin of safety as related to availability of electric power to
safety related loads.
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.

revise the Administrative Controls Section (6.0) of the Technical
Specifications (TS) for Hope Creek Generating Station to reflect
organizational changes and resultant management title changes. As
indicated on the marked-up pages in Attachment 2, PSE&G requests that:
1) Vice President and Chief Nuclear Officer will be replaced with Chief
Nuclear Officer and President - Nuclear Business Unit in TS 6.1.2,
6.2.1.c, 6.5.2.4.3.g, 6.5.2.4.4.a, 6.5.2.4.4.b, 6.5.2.6, 6.6.1.b,

6.7.1.a, 6.7.1.c.
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 not involve a significant increase in the probability or
consequences of an accident previously evaluated.
The proposed management title changes from Vice President and
Chief Nuclear Officer to Chief Nuclear Officer and President -
Nuclear Business Unit or Vice President - Nuclear Operations, and
from General Manager - Quality Assurance and Nuclear Safety to
Director - Quality Assurance and Nuclear Safety Review are
administrative in nature and do not affect assumptions contained in
the plant safety analysis, the physical design and/or operation of
the plant, nor do they affect Technical Specifications that preserve
safety analysis assumptions. Therefore, the proposed changes do not
[[Page 32372]] involve a significant increase in the probability or
consequences of an accident previously evaluated.
2. Will not create the possibility of a new or different kind of
accident from any accident previously evaluated.
The changes being proposed are purely administrative and will
not lead to material procedure changes or to physical modifications.
Therefore, the proposed changes do not create the possibility of a
new or different type of accident from any accident previously
evaluated.
3. Will not involve a significant reduction in a margin of
safety.
The changes being proposed are administrative in nature and do
not relate to or modify the safety margins defined in and maintained
by the Technical Specifications. The changes discussed herein do not
reduce the Technical Specification safety margin since all
organizational responsibilities are being adequately implemented,
and all personnel in place are properly qualified. Therefore, 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.

Tennessee Valley Authority, Docket Nos. 50-327 and 50-328, Sequoyah
Nuclear Plant, Units 1 and 2, Hamilton County, Tennessee
Date of amendment request: May 19, 1995 (TS 95-07)
Description of amendment request: The proposed change would (1)
modify Surveillance Requirement (SR) 4.1.1.3 to allow suspension of the
end of life (EOL) moderator temperature coefficient (MTC) surveillance
measurement provided the benchmark criteria and the Revised Prediction
as documented in the Core Operating Limits Report (COLR) are satisfied.
The SR would also indicate that the data required for the calculation
of the Revised Prediction is provided in the Most Negative Temperature
Coefficient Limit Report per Specification 6.9.1.15. In addition, a
grammatical error affecting the Unit 1 SR would be corrected; (2)
modify Technical Specifications (TS) 6.9.1.14, COLR, by adding to the
list of references: WCAP-13749-P-[A], ``Safety Evaluation Supporting
the Conditional Exemption of the Most Negative EOL Moderator
Temperature Coefficient Measurement,'' May 1993 (Proprietary)
(Methodology for Specification 3.1.1.3 - Moderator Temperature
Coefficient); (3) add Specification 6.9.1.15, which would require that
the Most Negative MTC Report be prepared at least 60 days prior to the
date the limit would become effective and be maintained on file. Also,
the TS would require that the data required for the determination of
the Revised Prediction of the 300 ppm/RTP MTC per WCAP-13749-P-[A] be
included in the report.
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:
TVA has evaluated the proposed technical specification (TS)
change and has determined that it does not represent a significant
hazards consideration based on criteria established in 10 CFR
50.92(c). Operation of Sequoyah Nuclear Plant (SQN) in accordance
with the proposed amendment will not:
1. Involve a significant increase in the probability or
consequences of an accident previously evaluated.
The conditional exemption of the most negative moderator
temperature coefficient (MTC) measurement does not change the most
negative MTC surveillance requirement (SR) and limiting condition of
operation (LCO) limits in the TSs. Since these MTC values are
unchanged, and since the basis for the derivation of these values
from the safety analysis moderator density coefficient (MDC) is
unchanged, the constant MDC assumed for the Updated Final Safety
Analysis Report (UFSAR) safety analyses will also remain unchanged.
Therefore, no change in the modeling (i.e., probabilities) of the
accident analysis conditions or response is necessary in order to
implement the change to the conditional exemption methodology. In
addition, since the constant MDC assumed in the safety analyses is
not changed by the conditional exemption of the most negative MTC SR
measurement, the consequences of an accident previously evaluated in
the UFSAR are not increased. The dose predictions presented in the
UFSAR for a steam generator tube rupture remain valid such that more
severe consequences will not occur. Additionally, since mass and
energy releases for a loss-of-coolant accident and a steamline break
are not increased as a result of the unchanged MDC, the dose
predictions for these events presented in the UFSAR also remain
bounding.
2. Create the possibility of a new or different kind of accident
from any previously analyzed.
Since the end-of-life MTC is not changed by the conditional
exemption methodology of WCAP-13749-P, the possibility of an
accident, which is different than any already evaluated in the
UFSAR, has not been created. No new or different failure modes have
been defined for any system or component nor has any new limiting
single failure been identified. Conservative assumptions for the MDC
have already been modeled in the UFSAR analyses. These assumptions
will remain valid since the conditional exemption methodology
documented in WCAP-13749-P does not change the safety analysis MDC
nor the TS values of the MTC.
3. Involve a significant reduction in a margin of safety.
The conditional exemption methodology is documented in WCAP-
13749-P. This WCAP has been evaluated (Reference: SECL 93-117,R1)
relative to the design basis, including the TSs, and has been
determined to bound the conditions under which the specifications
permit operation. The results as presented in the UFSAR remain
bounding since the MDC assumed in the safety analyses and the
limiting conditions for operation and SR MTCs in the TSs remain
unchanged. Therefore, the margin of safety, as defined in the bases
to these TSs, is not reduced.
The NRC has reviewed the licensee's analysis and, based on
thisreview, 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.

months. [[Page 32373]]
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:
TVA has evaluated the proposed technical specification (TS)
change and has determined that it does not represent a significant
hazards consideration based on criteria established in 10 CFR
50.92(c).
Operation of Sequoyah Nuclear Plant (SQN) in accordance with the
proposed amendment will not:
1. Involve a significant increase in the probability or
consequences of an accident previously evaluated.
The proposed change is temporary and allows a one-time extension
of Surveillance Requirement 4.3.2.1.3 for Cycle 7 to allow
surveillance testing to coincide with the seventh refueling outage.
The proposed surveillance interval extension will not cause a
significant reduction in system reliability nor affect the ability
of the systems to perform their design function. Current monitoring
of plant conditions and continuation of the surveillance testing
required during normal plant operation will continue to be performed
to ensure conformance with TS operability requirements. Therefore,
this change does not involve a significant increase in the
probability or consequences of an accident previously evaluated.
2. Create the possibility of a new or different kind of accident
from any previously analyzed.
Extending the surveillance interval for the performance of
specific testing will not create the possibility of a new or
different kind of accidents. No changes are required to any system
configurations, plant equipment, or analyses. Therefore, this change
will not create the possibility of a new or different kind of
accident from any previously evaluated.
3. Involve a significant reduction in a margin of safety.
Surveillance interval extensions will not impact any plant
safety analyses since the assumptions used will remain unchanged.
The safety limits assumed in the accident analyses and the design
function of the equipment required to mitigate the consequences of
any postulated accidents will not be changed since only the
surveillance test interval is being extended. Historical performance
generally indicates a high degree of reliability, and surveillance
testing performed during normal plant operation will continue to be
performed to verify proper performance. Therefore, the plant will be
maintained within the analyzed limits, and the proposed extension
will not significantly reduce the margin of safety.
The NRC has reviewed the licensee's analysis and, based on
thisreview, 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.

TU Electric Company, Docket Nos. 50-445 and 50-446, Comanche Peak
Steam Electric Station, Units 1 and 2, Somervell County, Texas
Date of amendment request: May 1, 1995
Brief description of amendments: The proposed amendment would: (1)
reduce the minimum fuel oil volume requirement during MODES 5 and 6,
for OPERABLE emergency diesel generators (EDG), and (2) allow continued
OPERABLE status of diesel generators during all MODES, for 48 hours
with greater than 6-day supply of diesel fuel for the associated diesel
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. Do the proposed changes involve a significant increase in the
probability or consequences of an accident previously evaluated?
REDUCTION IN MINIMUM DIESEL FUEL STORED VOLUME WHILE SHUTDOWN
The first proposed change reduces the diesel fuel oil inventory
required during plant shutdown conditions (MODES 5 and 6). The
current fuel oil inventory requirement is the same for plant
operation (MODES 1, 2, 3 and 4) and for plant shutdown. This current
inventory requirement is based upon the seven days continuous
operation of a diesel generator at its rated capacity which
encompasses all load demands for the Loss of Coolant Accident
concurrent with a Loss of Offsite Power (LOCA/LOOP) scenario.
Because of reduced temperature and pressure, LOCA/LOOP is a less
significant and probable event in MODES 5 and 6. The bounding
scenario is considered to be a Loss of Offsite Power (LOOP) while
the plant is shutdown (in MODES 5 and 6). The new diesel fuel oil
inventory required during plant shutdown conditions is based on
LOOP. Because this change only affects diesel fuel inventory, there
is no impact on the probability of an accident. The consequences of
LOOP event are unchanged since sufficient fuel remains available to
allow the diesel generators to support mitigation of the event.
Because seven days of fuel are required, there is no change in the
consequences of any event which requires the diesel generators.
Therefore, there is no significant increase in the probability or
consequences of an accident previously evaluated as a result of this
proposed change.
ADDITION OF REMEDIAL ACTION TO RESTORE THE STORED VOLUME OF
DIESEL FUEL
The second proposed change applies to all MODES of operation.
This change allows the diesel generator to remain OPERABLE if the
fuel oil inventory falls below the minimum required in the storage
system (i.e., fuel volume for 7-day operation of the diesel
generator) but remains above a fuel volume for 6 days operation of
the diesel generator. The minimum required fuel oil volume must be
restored within 48 hours of falling below the limit. This relaxation
by 48 hours allows sufficient time to replenish the required fuel
oil volume and complete any required analysis prior to fuel oil
addition to the storage tank. Because this change only affects
diesel generator fuel inventory, there is no impact on the
probability of an accident. Since the fuel oil replenishment can be
obtained in less than six days after an event, there is no
significant increase in the probability of a loss of all AC power
(i.e., Station Blackout). Because the remaining fuel oil volume is
larger than 6-day fuel supply and actions are initiated to obtain
replenishment within this brief period, the proposed change does not
involve a significant increase in the consequences of an accident
previously evaluated.
2. Do the proposed changes create the possibility of a new or
different kind of accident from any accident previously evaluated?
REDUCTION IN MINIMUM DIESEL FUEL STORED VOLUME WHILE SHUTDOWN
The first proposed change reduces the diesel fuel oil inventory
required for plant shutdown conditions. As described above, LOOP is
the limiting condition for diesel fuel oil inventory requirements
for a plant in the shutdown condition. As the proposed fuel
inventory is adequate for a shutdown LOOP and no hardware changes or
system operation changes are involved, no new failure modes are
introduced and hence, no new or different accidents from any
previously evaluated are created.
ADDITION OF REMEDIAL ACTION TO RESTORE THE STORED VOLUME OF
DIESEL FUEL
The second proposed change only affects diesel generator fuel
inventory as well. There are no hardware changes and no changes in
system operations involved; therefore, no new or different accidents
from any accident previously evaluated are created.
3. Do the proposed changes involve a significant reduction in a
margin of safety?
The intent of the Technical Specification is to conservatively
assure sufficient fuel to assure diesel generator operation to
support mitigation of postulated events. This intent is accomplished
by conservatively assuring a seven day supply of fuel. Seven days
fuel supply is considered sufficient to support the initial
mitigation activities, identify the need for additional fuel,
arrange for delivery, test and then add fuel to the storage tanks,
if needed. The current diesel fuel oil inventory for operating
conditions (MODES 1, 2, 3 and 4), is sufficient to conservatively
support seven days of diesel generator operation for a LOCA with
LOOP condition.
REDUCTION IN MINIMUM DIESEL FUEL STORED VOLUME WHILE SHUTDOWN
[[Page 32374]]
The proposed diesel fuel oil inventory for shutdown conditions
(MODES 5 and 6), is adequate to conservatively support seven days of
diesel generator operation for LOOP conditions. The proposed
reduction in inventory between operating and shutdown conditions
continues to support the different transient conditions which are
applicable to the different modes of operation. Even though the
minimum storage requirement during shutdown is being reduced, the
basis of this specification continues to be conservatively satisfied
and therefore this license amendment request does not involve a
significant reduction in a margin of safety.
ADDITION OF REMEDIAL ACTION TO RESTORE THE STORED VOLUME OF
DIESEL FUEL
The second proposed change which is applicable to all MODES of
operation, allows 48 hours to restore diesel generator fuel oil
inventory to the seven-day level as long as the inventory does not
fall below the six-day level. The probability of a LOOP during this
period is low. The 6-day fuel oil supply is calculated with adequate
margin similar to the calculation of 7-day fuel oil inventory. In
spite of the potential that there may be slightly less fuel
available inlenishment within this brief period. Based on this and
the low probability of an event during this brief period, it is
considered that this change request 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
amendment request involves no significant hazards consideration.
