Docket No. 50-10 REVISED ORDER FOR MOD IF I CATION OF LICENSE I.

Conmonwealth Edison Company (the. licensee) is the holder of Facility Operating License.No. DPR-2, which authorizes the operation of the *oresden Nuclear Power Station, Unit No. l at steady-state reactor power levels not in excess of 700 megawatts thermal (rated power).

The facility consists of a boiling water reactor located at the license~'s site i.n Grundy County, Illinois.

  • I I.

On November 4, 1977, the Union of Concerned Scientists (UCS) filed with the.Conmissiona "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 Conmission denied certain aspects tif 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 Conmission reaffirmed its April 13, 1978 decision

. regarding the possible* shutdown of operating reactors.

HO\\llever, the Co11111ission's May 23, 1980 decision di.rected licensees and the NRC staff to undertake certain actions~

With respect to environmentaL qualification of safety-related electrical equipment, the Corrmission detennin~d that the pr9visions of the two staff documents - the Divis.ion of Operating Reactors "Guidelines *for Evaluating Environmental Qualification of Class lE Electrical Equipment*

in Operating Re~ct6rs" (DO~ Guideii_nes) and NUREG-0588, *interim Staff Position on Environmental Qualification of Safety-Related Electrical Equipment," Decemb.er 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 Criterio~ (GDC-4)~ which relate to envi-ronmental qualification of safety-related electrical equipment~" The Co11111ission directed, for replacement parts in operating plants, "unless th~re are sound reasons to the contrary, the 1974 standard in NUREG-0588

\\ltill apply."

The Corrmission also directed the staff to complete its I

1 review of the informatiot sought from licensees by Bulletin. 79-0lB and to coJ11)lete its review of environmental qualification o~ safety-related electrical equipment in al1_operating plants, including the publication*

of Safety Evaluation Reports, by February l, 1981.

The Corrmission 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. Bull et in 79-01 B was requested f ram these license.es by a

. series of letters and meetings during the months of. February and March, 1980.

iiu;>osed a deadline that, "by no later than June 30,-1982 all safety-rel~ted electrical equipment in all operating plants ~hall be qualified to the DOR Guidel_ines or NUREG-0588."

The Conmission requested the staff to,*

11k.eep the ColTlllission and the public apprised of any further findings of inco~lete 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 Conmi ssion.

The Conmi ss ion further directed the staff to add certain documentation requirements to each license after the specific requirements were approved by the Conmission.

The ColTlllission also pointed out that the *various

_deadlines imposed in its Order, *do not"excuse a licensee from the

- obl i gat.i on to modify or replace inadequate equipment promptly."

I I I-.

The information developed dµring 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 pro~t co~letion of any plant modification needed to assure conformance with the DOR Guidelines or NUREG-0588.

A sigrdficant aspect of this review.

is the timely submittal of enviro_nmental qualification information by the operating plant licensees to enable-the staff -to co_mplete its review in accor_dance with the Co111t1ission 1 s Order.

The staff has a program presently underway to reevaluate, using the DOR Guidelines ~nd NUREG-0588, the qualifications of safety-related electrical equipment exposed

.l to environments that may exist following postulated accidents *. These acc1 dents are Loss of Cool ant Accident and Main Steam Line Break inside containment, 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 March 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 cofll)lete package, including justificati-0n for methods used, was requested *

.. Clarification was provided by supplemental information, bri~fings, and in some cases, meetings with the licensee.

Timely completion of the staff's review of environmental qualification of electrical equipment and t.imely co~letion of needed modifications by the licensee is require~ 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, I

to date, is incoltl>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 immediately.

IV.

Accordingly, pursuant to the Atomic Energy Act of 1954, as amended, and

  • the Contnission's regulations in 10 CFR Parts 2 and 50, IT IS ORDERED THAT EFFECTIVE IMMEDIATELY Facility Operating License No. DPR-2 is hereby amended to add the following provisions:

11 Information which fully and COlfPtlletely responds to the staff's request as specified in NRC's letters dated March 6, 1980, and

.March 28, 1980, shall be submitted to the Director, Division of Licensing by the licensee not later than November l, 1980.

11 An earlier response is encouraged to facilitate staff review and issuance of the safety evaluation report.

The licensee or any person whose interest*

may be affected by this Order may request a hearing within 20 days of the date of publication of this Revised Order in the Federal Register.

Any request for a hearing shall be addre*ssed. to the Director, Office of.

Nuclear.Reactor Regulation, U.S. Nuclear Regulatory Corrmission, Washington;

o. c.

20555.

A copy of the request should also be sent to the Executive Legal Director, U. S. Nuclear Regulatory Co0111ission, Washington, D. C.

20555, and to Isham, Lincoln & Beale, Counselors at Law, One First National Plaza, 42nd Floor, Chicago, Illinois 60603, attorney for the licensee.

If a hearing is held concerning this Order, the issue to be considered at the hearing shall be whether the license should be modified to require submission of information as set forth in Section IV. of the Order.

Operating of the facility on terms consistent with this Order is not stayed by the pendency of any proceedings on the Order. This Order revises, in its entirety, the Order issued.August 29, 1980 (45 FR I

60065, September 11, 1980).

The* information developed during this proceeding emphasizes the importance of adequate documentation, the prollllt completion of the revi.ew of environ-mental qualification of safety-related elec1;.rical equipment, and the

. prollllt cofi\\>letion of any plant modification needed to assure conforinance with the DOR Guidelines or NUREG-0588.

A significant aspect of this review is the timely submittal of envir~nmental qu.alification inforination by the operating plant licensees to enable the staff to complete its review in accordance with the Conmission'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 0
