NUCLEAR REGULATORY COMMISSION
[Docket No. 50-280 and 50-281]
Virginia Electric and Power Company, Surry Power Station;
Environmental Assessment and Finding of No Significant Impact
The U.S. Nuclear Regulatory Commission (the Commission) is
[[Page 44496]]
considering issuance of an exemption from certain requirements of its
regulations for Facility Operating License No. DPR-32 and Facility
Operating License No. DPR-37, issued to Virginia Electric and Power
Company (the licensee), for operation of the Surry Power Station
located in Surry County, Virginia.
Environmental Assessment
Identification of Proposed Action
The proposed action would exempt Virginia Electric and Power
Company from the requirements of 10 CFR 70.24(a), which requires a
monitoring system that will energize clear audible alarms if accidental
criticality occurs in each area in which special nuclear material is
handled, used, or stored. The proposed action would also exempt the
licensee from the requirements to maintain emergency procedures for
each area in which this licensed special nuclear material is handled,
used, or stored to ensure that all personnel withdraw to an area of
safety upon the sounding of the alarm, to familiarize personnel with
the evacuation plan, and to designate responsible individuals for
determining the cause of the alarm, and to place radiation survey
instruments in accessible locations for use in such an emergency.
The proposed action is in accordance with the licensee's
application for exemption dated January 28, 1997, as supplemented March
24, 1997.
The Need for the Proposed Action
The purpose of 10 CFR 70.24 is to ensure that if a criticality were
to occur during the handling of special nuclear material, personnel
would be alerted to that fact and would take appropriate action. At a
commercial nuclear power plant the inadvertent criticality with which
10 CFR 70.24 is concerned could occur during fuel handling operations.
The special nuclear material that could be assembled into a critical
mass at a commercial nuclear power plant is in the form of nuclear
fuel; the quantity of other forms of special nuclear material that is
stored on site is small enough to preclude achieving a critical mass.
Because the fuel is not enriched beyond 4.1 weight percent Uranium-235
and because commercial nuclear plant licensees have procedures and
features designed to prevent inadvertent criticality, the staff has
determined that inadvertent criticality is not likely to occur due to
the handling of special nuclear material at a commercial power reactor.
The requirements of 10 CFR 70.24(a), therefore, are not necessary to
ensure the safety of personnel during the handling of special nuclear
materials at commercial power reactors.
Environmental Impacts of the Proposed Action
The Commission has completed its evaluation of the proposed action
and concludes that there is no significant environmental impact if the
exemption is granted. Inadvertent or accidental criticality will be
precluded through compliance with the Surry Power Station Technical
Specifications (TS), the design of the fuel storage racks providing
geometric spacing of fuel assemblies in their storage locations, and
administrative controls imposed on fuel handling procedures. TS
requirements specify reactivity limits for the fuel storage racks and
minimum spacing between the fuel assemblies in the storage racks.
Appendix A of 10 CFR Part 50, ``General Design Criteria for Nuclear
Power Plants,'' Criterion 62, requires that criticality in the fuel
storage and handling system shall be prevented by physical systems or
processes, preferably by use of geometrically safe configurations. This
is met at Surry Units 1 and 2, as identified in the TS.
Surry TS Section 5.4, Fuel Storage, states that the new fuel
assemblies are stored vertically in an array with a distance of 21
inches between assemblies to assure that the effective neutron
multiplication factor, Keff, will remain 0.95 if
fully flooded with unborated water, and to assure Keff
0.98 under conditions of low-density optimum moderation.
The spent fuel assemblies are stored vertically in an array with a
distance of 14 inches between assemblies to assure Keff
0.95 if fully flooded with unborated water.
The proposed exemption would not result in any significant
radiological impacts. The proposed exemption would not affect
radiological plant effluents nor cause any significant occupational
exposures since the TS, design controls, including geometric spacing of
fuel assembly storage spaces, and administrative controls preclude
inadvertent criticality. The amount of radioactive waste would not be
changed by the proposed exemption.
The proposed exemption does not result in any significant
nonradiological environmental impacts. The proposed exemption involves
features located entirely within the restricted area as defined in 10
CFR Part 20. It does not affect nonradiological plant effluents and has
no other environmental impact. Accordingly, the Commission concludes
that there are no significant nonradiological environmental impacts
associated with the proposed action.
Alternatives to the Proposed Action
Since the Commission has concluded that there is no measurable
environmental impact associated with the proposed action, any
alternatives with equal or greater environmental impact need not be
evaluated. As an alternative to the proposed exemption, the staff
considered denial of the requested exemption. Denial of the request
would result in no change in current environmental impacts. The
environmental impacts of the proposed action and the alternative action
are similar.
Alternative Use of Resources
This action does not involve the use of any resources not
previously considered in the ``Final Environmental Statement for the
Surry Power Station.''
Agencies and Persons Consulted
In accordance with its stated policy the NRC staff consulted with
Mr. Foldesi of the Virginia Department of Health on August 15, l997,
regarding the environmental impact of the proposed action. The State
official had no comments.
Finding of No Significant Impact
Based upon the environmental assessment, the Commission concludes
that the proposed action will not have a significant effect on the
quality of the human environment, Accordingly, the Commission has
determined not to prepare an environmental impact statement for the
proposed action.
For further details with respect to the proposed action, see the
licensee's letter dated January 28, 1997, as supplemented March 24,
1997, which is available for public inspection at the Commission's
Public Document Room, which is located at The Gelman Building, 2120 L
Street, NW., Washington, DC, and at the local public document room
located at the Swem Library, College of William and Mary, Williamsburg,
Virginia.
Dated at Rockville, Maryland, this 15th day of August 1997.
