REVISED ORDER FOR MODIFICATION OF LICENSE I.
The Commonwealth Edisor Company (licensee) is the holder of Facility Operating License No. DPR-25 which authorizes the operation of the Dresden Nuclear Power Station Unit 3 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 near Morris, Illinois.
II.
On November 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 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 Commiss'en reaffirmed its April 13, 1978 decision
- 009300 f q
i 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 i
equipnent, the Comnission 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 Potition on Environnental 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 Critecion (GDC-4), which relate to envi-ronnental 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 information sought from licensees by Bulletin 79-OlB 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 1Bulletin 79-01B was not sent to licensees for plants under review as i
part of the staff's Systematic Evaluation Program.
The information sought by Bulletin 79-01B was requested from these licensees by a series of letters and meetings during the months of Fjebruary and March, 1980.
1
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 Comaission 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
, Commi ss i on.
The Commission further directed the staff to add certain documentation requirements to each license af ter 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 modify or replace inadequate equipment promptly."
III.
The information developed during this proceeding emphasizes the importance of adequate documentation, the prompt coiapletion of the review of environ-mental qualification of safety-related electrical equipment, and the pronpt completion of any plant modification needed to a sure confornance with the DDR Guidelines or NUREG-0588. A significant aspect of this review is the timely submittal of environmental qualification information by the operating plant licensees +.o enable the staff to complete its review
-in accordance with the Commission's Order.
The staff has a program presenlly underway to reevaluate, using the D0R Guidelines and NUREG-0588, the qualifications of safety-related electrical equipment exposed
4 O
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 Creaks inside and outside i
containment.
In this connection the licensee was requested by 18E Bulletin 79-01B 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 completion of the l
staff's review of environmental qualification of electrical equipment and timely completion of needed modifications by the licensee is f
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.
llowever, the licensee's response, to date, is inconplete.
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 innediately.

l Accordingly, pursuant to the Atomic Energy Act of 1954, as amended, and i
i the Commission's regulations in 10 CFR Parts 2 and 50, IT IS ORDERED THAT EFFECTIVE IMMEDIATELY Facility Operating License No. DPR-25 is hereby amended to add the following provisions:

Any request for a hearing will not stay the effective date of this Order.
