ORDER FOR MODIFICATION OF LICENSE I.
The Hebraska Public Power District (licensee) is the holder of Facility Operating License No. DPR-46 which authorizes the operation of the Cooper Nuclear Power Station at steady state reactor power levels not in excess of 2381 megawatts thermal (rated power). The facility consists of a bcling water reactor located at the licensee!s site in Nemaha County, Nebraska.
II.
Or 'iovember 4,1977, the Union of Concerned Scientists (UCS) filed with the Commission a " Petition for Emergency and Remedial Relief." The petition sought action in two areas: fire protection for electrical cabies, and environmental qualification of electrical ceaponents.
By Mencrandum 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 Commission reaffirmed its April 13, 1978 decision 8009260601
o
. regarding the tssible shutdown of operating reactors.
However, the g
Commission /s May 23, 1980 d'ecision directed licensees and the NRC staff to undertake certain actions.
With respect to environmental qualification of safety-related electrical equipment, the Commission detemined that the provisions of the two staff documents - the Division of Operating Reactors " Guidelines for 1
Evaluating Environmental Qualification of Class lE Electrical Equipment in Operating Reactors" (00R Guidelines) and NUREG-0588, " Interim Staff Pcsition on Environmental Qualification of Safety-Related Electrical Equipment," December 1979 "fom 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 Commission directed, for replacement parts in operating plants, "unless there are sound reasons to the contrary, the 1974 standard in NUREG-0588 will apply." The Commission also directed the staff to complete its 1
review of the infomation 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 1
Bulletin 79-OlB was not sent to licensees for plants under review as part of the staff!s Systematic Evaluation Program. The infomation sought by Bulletin 79-OlB was requested from these licensees by a series of letters and meetings during the months of February and March, 1980.
0
- 2 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 D0R Guidelines or NUREG-0588." The Commission requested the staff to, " keep the Canaission and the public apprised of any further findings of incomplete 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 Comni ssion.
The Commission further directed the staff tc add certain documentation requirements to each license after the specific requirements 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 nodify or replace inadequate equipnent promptly."
III.
The information developed during this proceeding emphasizes the importance of adequate documentation, the prompt completion of the review of environ-mental qualification of safety-related electrical equipment, and the r0cpt completion of any plant modification needed to assure conformance with the D0R Guidelines or NUREG-0588.
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 Canmission's Order. The staff has a program cresently underway to reevaluate, using the 00R Guidelines and NUREG-0588, the qualifications of safety-related electrical equipment exposed
. to environments that may 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 79-018 of January 14, 1980 to provide a detailed review of the environmental qualification of Class lE 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 was provided by supplemental information, briefings, and in some cases, meetings with the licensee.
Timely canpletion of the staff 's review of environmental qualification of electrical equipment and ticely completion of needed modifications by the licensee is
-equired to provide continuing reasonable assurance of public health and safety.
Such completion is dependent on the prompt receipt of a complete response by the licensee to the staff 's requests for information.
- -:owever, the licensee /s response, to date, is incomplete.
Therefore, I have concluded that the public health, safety, and interes*
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.
