Unit No. 2

ORDER FOR MODIFICATION OF LICENSE I.

Commonwealth Edison Company (the licensee) is the holder of Provisional Operating License No. DPR-19, which authorizes the operation of the Dresden Nuclear Power Station, Unit No. 2 at steady-state reactor power levels not in excess of 2527 megawatts thermal (rated power). The facility consists of a boiling water reactor located at the licensee's site in Grundy County, Illinois.

II.

On November 4,1977, the Union of Concerned Scientists (UCS) filea with the Commission a " Petition for Emergency and Remedial Relief." The petition sought action in two areas:

fire protection for electrical cables, and environmental qualification of electrical components.

By Memorandum anc Order dated April 13,1978 (7 NRC 400), the Commission cenied certain aspects of the petition ano, witn 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 deci sion l

regarding the possible shutdown cf 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 Commission determined that the provisions of the two staff documents - the Division of Operating Reactors " Guidelines for Evaluating Environmental Qualification of Class lE 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 nust 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 l

there are sound reasons to the centrary, tne 1974 standaro in NUREG-0588 will apply." Tne Commission also cirected tne staff to complete its 1

review of the information sought from licensees by Bulletin 79-01B ana to complete its review of environmental qualification of safety-related electrical equipment in all operating plants, including tne publication of Safety Evaluation Reports, by Feoruary 1,1981.

The Commission 1

Bulletin 79-013 was not sent to licensees for plants uncer review as part of tne staff's Systematic Evaluation Program.

Tne information sought Dy Bulletin 79-019 was requestec from tnese licensees by a series of letters and meetings cu. ring tne montns of February and March, 1930.

3 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 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 Commission.

The Commis: ion further directed the staff to add certain documentation requirements to each license af ter the specific requirements were approved oy the Commission.

The Commission also pointed out tnat the various deadlines imposed in its Order, "do not excuse a licensee from tne obligation to modi fy or replace inadequate equipment promptly."

III.

ine information developed during tnis proceeding emphasizes the importance of acequate documentation, the prompt completion of the review of environ-mental qualification of safety-related electrical equipment, and the prompt completion of any plant modification neeced to assure conformance with the 00R Guidelines or NUREG-0588. A significant aspect of tnis review is tne timely submittal of environmental qualification information by tne operating plant licensees to enaole tne staff to complete its review in accorcance witn tne Commission's Order.

. to environments that may exist following postulated accidents. These accidents are Loss of Coolant Accident and Mrin Steam Line Break inside containment, and High Energy Line Breaks inside and outside containment.

In this connection the licensee was requested by our letter of March 6, 1980, as modified by our letter of March 28, 1980, to provice information on emergency procedures and safety related systems. The licensee was requested to cefine and provide the basis for tne hostile environment, inside and outside containment. This hostile environment would then be used, by the licensee, in the cetermination of unqualified equipment. A complete package, including justification for metnods used, was requestec.

Clarification was proviced by supplemental information, briefings, ano, in some cases, meetings with tne licensee. Timely completion of tne staff's review of er vironmental qualification of electrical equipment and timely completion of neecea mocifications by the licensee is required to provice 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. However, the licensee's response, to date, is incomplate.

Therefore, I have concluded that the publ!c health, safety, and interest required that a firm schedule for the timely submission of all the informa-tion previously requested by the staff snould be established Dy Orcer effective immediately.
