Docket No. 50-338 (North Anna Power Station,

Unit No. 1)
)
ORDER FOR MODIFICATION OF LICENSE I.
Virginia Electric and Power Company (licensee) is the holder of Lice,se No.
NPF-4, which authorizes the operation of the North Anna Power Station Unit No.1 at steady state reactor power levels not in excess of 2775 megawatts thermal (rated power).
The facility consists of a Pressurized 4
Water Reactor located at the licensee's site in Louisa County, Virginia.

On November 4,1977, the Union of Concerned Scientists (UCS) filed with the Commission a " Petition for Emercancy and Remedial Reliet." The petition sought action in two areas:
fire protection for electrical cables, and environmental qualification of electrical components.
By Memorandum and Order dated April 13,1978 (7 NRC 400), the Commission denied certain aspects of the petition and, with respect to other aspects, ordered the NRC staff to take several related actions.
UCS filed a Petition for Reconsideration on May 2,1978.
By Memorandum and Order, dated May 23, 1980, the Comission reaffirmed its April 13, 1978 decision 80092606 %

. regarding the possible shutdown of operating reactors.
However, the Commission's May 23, 1980 decision directed licensees and the NRC staff to undertake certain actions.
With respect to environmental qualification of safety-related electrical equipment, the Comission determined that the provisions of the two staff documents - the Division of Operating Reactors " Guidelines for Evaluating Environmental Qualification of Class 1E Electrical Equipment in Operating Reactors" (DOR Guidelines) and NUREG-0588, " Interim Staff Position on Environmental Qualification of Safety-Related Electrical Equipment," December 1979 " form the requirements which licensees and applicants must meet in order to satisfy those aspects of 10 CFR Part 50, Appendix A General Design Criterion (GDC-4), which relate to envi-ronmental qualification of safety-related electrical equipment." The Ccmmission directed, for replacement parts in operating plants, "unless there are sound reasons to the contrary, the 1974 standard in NUREG-0588 will apply." The Comission also directed the staff to complete its 1
review of the information sought from licensees by Bulletin 79-01B and to complete its review of environmental qualification of safety-related electrical equipment in all operating plants, including the publication of Safety Evaluation Reports, by February 1,1981.
The Commission i
Bulletin 79-018 was not sent to licensees for plants under review as part of the staff's Sy5tematic Evaluation Program.
The information sought by Bulletin 79-315 was recuested from these licensees by a series of letters and meetings dud ng the months of February and March, 1980.

imposed a deadline that, "by no later than June 30, 1982 all safety-related electrical equipment in all operating plants shall be qualified to the 00R Guidelines or NUREG-0588." The Commission requested the staff to, " keep the Commission and the public apprised of any further findings of incorplete environmental qualification of safety-related electrical equipment, along with corrective actions taken or planned,"
and requested the staff to provide bi-monthly progress reports to the Commi ssion.
The Commission further directed the staff to add certain documentation requirements to each license after the specific requic;ments were approved by the Commission.
The Commission also pointed out that the various deadlines imposed in its Order, "do not excuse a licensee from the obligation to modify or replace inadequate equipment promptly."
III.
The information developed during this proceeding em,phasizes the importance of adequate documentation, the prompt completion of the review of environ-mental qualification of safety-related electrical equipment, and the prompt ccmpletion of any plant modification needed to assure conformance with the DDR Guidelines or NUREG-0558.
A significant aspect of this _ review is the timely submittal of environmental qualification information by the operating plant licensees to enable the staff to complete its review in accordance with the Commission's Order.
The staff has a program presently underway te reevaluate, usine the DDR Guidelines and NUREG-058S, the cualifications of safety-related electrical equipment exposec

-4 to environments that ray exist following postulated accidents. These accidents are Loss of Coolant Accident and Main Steam Line Break inside containment, and High Energy Line Breaks inside and outside containment.
In this connection the licensee was requested by I&E Bulletin 79-01B dated January 14, 1980 to provide a detailed review of the environ-mental qualification of Class 1E electrical equipment.
This review was to include all equipment required to function under postulated accident conditions, both inside and outside the primary containment, and recognize all conditions specified in the bulletin.
Evidence of qualification together with methods and justification, was requested.
Clarification wa; provided hy supplemental information, briefings, and in some cases, meetings with the licensee.
Timely congletion of the staff's review of environmental qualification of electrical equipment and timely completion of needed modifications by the licensee is required to provide continuing reasonable assurance of public health and safety.
Such completion is dependent on the prompt receipt of a complete response hy the licensee to the staff's requests for information.
However, the licensee's response, to date, is incomplete.
Therefore, I have concluded that the public health, safety, and interest require that a firm schedule for the timely submission of all the information previously requested by the staff should be established by Order effective immediately.
