' k 'N UNITED STATES OF AMERICA b
. NUCLEAR REGULATORY COMMISSION In the Matter of THE-TOLEDO EDIS0N COMPANY'AND THE CLEVELAND ELECTRIC ILLUMI-Docket No. 50-346 NATING COMPANY Davis-Besse Nuclear Power Station.
Unit No. 1 ORDER FOR MODIFICATION OF LICENSE 1.
The Toledo Edison Conpany (TECo) and The Cleveland Electric illuminating Company (the licensees) are the holders of Facility Operating License No.
NPF-3, which authorizes the operation of the Davis-Besse Nuclear Power Station, Unit No.1 at steady state reactor power levels not in excess of 2772 megawatts thermal (rated power). The facility consists of a pressurized
~
water reactor located at the licensee's site in Ottawa County, Ohio.
II.
On November 4,1977, the Union of Concerned Scientists (UCS) filed with the Comission a " Petition for Emergency and Remedial Relief." The petition sought action in two areas:
fire protection for electrical l
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 800919053/
a m
F 1
l' regarding the possible shutdown of operating reactors. However, the Conmission'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 Connission determined thct the provisions of the two staff documents - the Division of Operating Reet; ors " Guidelines for Evaluating Environmental Qualification of Class iE Electrical Equipment in Operating Reactors" (DDR 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 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 Connission also directed the staff to complete its 1
review of the information sought from licentees by Belletin 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 Connission l
1Bulletin 79-01B was not sent to licensees for plants under review as
-part of the staff's Systematic Evaluation Program. The information
'l sought by Bulletin 79-01B was requested from these licensees by a
' series of letters and meetings during tl.a months of February and March, 1980.
u.
I,i 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 DOR Guidelines or NUREG-0588." The Comission requested the staff to, " keep the Comission and the public apprised of any further findings of inconplete environmental qualification of safety-related
-electrical equipment, along with corrective actions taken or planned,"
and requested the staff to provide bi-monthlv progress reports to the Co rnission.
The Commission further directed the staff to add certain documentation requirements to each license after the specific requirements were approved by the Comission.
The Comission also pointed out that the various ceadlines imposed in its Order. "do not excuse a licensee from the obligation to modify or replace inadequate equipment promptly."
111.
The information developed during this proceeding emphasizes the inportance of adequate documentation, the prompt completion of the review of environ-rental qualification of safety-related electrical equipment, and the prompt completion of any plant modification needed to assure conformance with the 00R 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 Comission's Order.
The staff has a program
. presently underwdy to reevaluate, using the DUR Guidelines and NUREG-0588, the qualifications of safety-related electrical equipment exposed C--
.~

9 to' invironments 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.
t in this connection TECo was requested by 18E Bulletin 79-01B dated January 14, 1980, to provide a detailed review of the environmental qualification of Class IE electrical equipment.
This review was to incluua 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 TECo. Timely completion of the staff's review of environmental qualification of electrical equipment and timely completion of nouded modifications by TECo is required to provido con-tinuing reasonable assurance of public health and saf ety.
Such conplet ton is dependent on the prompt receipt of a coglete response by TECo to the staff's requests for information._ However, TECo's response, to dcte, 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 irraediately.
