NUCLEAR REGULATORY-COMMISSION In the Matter ofn NORTHERN STATES POWER COMPANY Docket Nos. 50-282

.(Prairie Island Nuclear Generating

)

and 50-306 Plant, Unit Nos. I and 2)

)

ORDER FOR MODIFICATION OF LICENSES I.

Northern States Power Company (licensee) is tne holder of License Nos.

OPR-42 and DPR-60 which authorize the operation of the Prairie Island Nuclear Generating Plant, Unit Nos. I and 2 at steady state reactor power levels not in excess of 1650 megawatts thernal (rated power).

The facilities consist of two Pressurized Water Reactors located at the licensee's site -

in Goodhue County, Minnesota.

II.

On. November 4,1977, the Union of Concernea 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 Commission reaffirmed its April 13, 1978 decision 1

a

-2 regarding the possible shutdown'of operating reactors.

However, the

- Commi ssion'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 1E Electrical Equipment 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 must meet in order to satisfy these espects of 10 CFR Part 53, 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 Commission also directed the ' staff to complete its l'

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 1

Eulletin 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; requested from :hese licensees ~ by a

_ series of letters.and meetings during the months 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 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 incomplete environmental qualification of safety-related electr'. cal equipment, along with corrective actions taken or planned,"

and requested the staff to provide bi-monthly progress reports to the Comi ssion.

The Comission 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 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 thi.s proceeding emphasizes the importance of adequate documentation, the prompt completion of the review of environ-mental qualificatio of safety-related. electrical equipment, and the prompt _ccmpletion of any plant modification needed to assure conformance

-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 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 qualifications of safety-related electrical equipment' exposed U;

t to environments that may exist following postulated accidents.. These accidents:are Loss of Coo'lant 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 IE 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

- staff's review of environnental qualification of electrical equipment

.and timely completion of needed modifications by the licensee is required to provide continuing reasonable assurance of public nealth 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 incomplete.

1Theref'

. ave 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;0rder effective immediately.
