)
REVISED ORDER FOR MODIFICATION OF LICENSE I.
Col111lonwealth Edis*on Co~any (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
- I I.
On November 4, 1977, the Union of Concerned Scientists (UCS) filed with the*Colllllission 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 I
Memorandum and Order dated April 13, 1978 (7 NRC 400), the Colll!lission denied certain aspects of the petition and, with respect to other aspects, i
ordered the NRC staff to take several related actions.
UCS filed a Petition for Reconsideradon on May 2, 1978.
By Memorandum and Order, dated May 23, 1980, the Conmission reaffirmed its April 13, 1978 decision 8011010 28i3 G
2 -
regarding the possible shutdown of operating reactors. However, the Comnission'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 Conmission 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 ReactorsM (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 inust 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 Conmission directed, for replacement parts in operating plants, "unless there are sound reasons to the contrary, the 1974 standard in NUREG-0588 will apply.* The Co1T1T1ission also directed the staff to complete its l
review of the information sought from licensees by Bulletin 79-0lB and to co~lete 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 Comnission Bulletin 79-0lB was not sent to licensees for plants under review as part of the staff's Systematic Evaluation Program.
The information sought by Bulletin 79-0lB was requested from these licensees by a sP.ries of letters and meetings during the nx>nths 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 $hall be qualified to the DOR Guidelines or NUREG-0588.*
The Conmission requested the staff to, akeep the Conmission and the public apprised of any further finding~ of incofl'\\Jlete environmental qualifi,cation of safety-related electrical equipment, along with corrective actions taken or planned,"
and requested the staff to provide bi-monthly progress reports to the Con111i ss ion.
The Corrmission further directed the staff to add certain documentation requirements to each license after the specific requirements were approved by the Comnission.
The Conmission 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."
I I I.
The information developed during this proceeding emphasizes the importance of adequate documentation, the prolJllt completion of the review of environ-mental qualification of safety-related electrical equipment, and the pro8'>t COfl'\\Jletion of any plant modification needed to assure conforA\\clnce with the DOR Guidelines or NUREG-0588.
A significant aspect of this review is the timely submittal of envir~nmental qualification information by the operating plant licensees to enable the staff to complete its review in accordance with the CoRmission's Order.
The staff has a program presently underway to reevaluate, using the DOR 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 ~ontainment, and High Energy Line Breaks inside and outside containment.
ln this connection the licensee was requested by our letter of March 6, 1980, as modified by our letter of ~arch 28, 1980, to provide information on emergency procedures and safety related systems. The licensee was requested to define and provide the basis for the hostile environment, inside and outside containment. This hostile environment would then be used, by the licensee, in the determination of unqualified equipment.
A COftl>lete package, including justification for methods used, was requested.
Clarification was provided by supplemental information, briefings, and in some cases, meetings with the licensee. Timely CO!ll>letion of the* staff's review of environmenta1 qua1ification of electrical equipment and timely COtll>letion 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 by the licensee to the staff's requests for information.
However, the licensee's response, to date, is inco~lete.
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 intnediately.
