HARTFORD ELECTRIC LIGHT-COMPANY Docket No. "9-336 WESTERN MASSACHUSETTS ELECTRIC COMPANY (Millstone Nuclear Power Station Unit No. 2)

4 ORDER FOR MODIFICATION OF LICENSE I.

Northeast Nuclear Energy Company, et al. (licensee) is the holder of License No. DPR-65, which authorizes the operation of the Millstone Nuclear Power Station, Unit No. 2 at steady state reactor power levels not in excess of 2700 megawatts thermal (rated power).

The facility consists of a Pressurized Water Reactor located at the licensee's site in the Town of Waterford, Connecticut.

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 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 Comissicn reaffirmed its April 13, 1978 decision

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 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 Ele' trical Equipment c

in Operating Reactors" (D0R Guidelines) and NUREG-0588, " Interim Staff Position on Environmental Qualification of Safety-Related Electrical Equipment," December 1979 " form the requirements which licensees and applicants rust 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-058S will apply." The Concission also directed the staff to complete its 1

review of the information 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 Fec' ruary 1,1981.

The Commission i

Bulletin 79-01B was not sent to licensees for plants under review as part of the staff's Systematic Evaluation Program.

The information sought by Bulletin 79-01B was reCJested from these licensees by a series of letters and reetings during the months of February and March, 1983.

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 Cor,ssion requested the staff to, " keep the Connission 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 Comi ssion.

The Commission further directed the staff to add certain documentation requirements to each license after the specific requirements were approved by the Comission.

The cc. mission also pointed out that the various deadlines imposed in its Order, "do not excuse a licensee from the obligation to mr>dify or replace inadequate equipment 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 prompt completion of any plant modification needed to assure conformance with the 00R Guidelines or 11UREG-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 underway to reevaluate, using the DDR Guidelines and NUREG-0588, the qualificati0r.s 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-OlB dated January 14, 1980 to provide a detailed review of the environ-mental 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 ir sore cases, meetings with the licensee.

Timely completion of the staff's review of environmental qualification of electrical equipment ar.d timely completion of needed modifications by the licensee is required to provide continuing reascnable 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.

icuever, the licensee's response, to date, is incomplete.

Therefore, I have concluded that the public health, safety, and interest require tha; a firm schedule for the timely submission of all the inforratien previously recuested by :he staff should be established z Order effective imrediately.
