ORDER FOR MCDIFICATION OF LICENSE I.

g f..

The Public Service Conpany of Colorado (licensee) is the holder of

5 License No. OPR-34 which authorizes the operation of the Fort St. Vrats ii

[

Nulcear Generating Station at steady state reactor pcwer levels not in excess of 842 megawatts thermal (rated power) with a current hold at 70%.

I 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 ccmponents.

By l[

Memorandum and Order dated April 13, 1978 (7 NRC 400), the Ccmmission

[

denied certain aspects of the petition and, with respect to other aspects, y

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 decisien

regarding the possible stutdown of operating reactors. However, the 3

Comission's May 23, 1980 decision directed licensees and the NRC staff 5j' to undertake certain actions.

With respect to environmental qualification of safety-related electrical equipment, the' Comission determined that the provisions of the two f

staff documents - the Division of Operating Reactors " Guidelines for z

Evaluating Environmental Qualification of Class lE Electrical Equipment in Operating Reactors" (00R Guidelines) and NUREG-0588, " Interim Staff Pos'ition 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."

Comission directeo,.for replacement parts in operating plants, "unless e

there are sound reasons to the contrary, the 1974 standard in NUREG-0588 i

j will a'ppiy." The Comission also' directed the staff to complete its 1

5 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 February 1,1981. The Comission

requirements to each -license after the specific requirements were approved

The information ' developed during this proceeding emphasizes the importance f

of' adequate documentation, the progt completion of the review of environ-mental'. qualification of. safety-relat'ed electrical equipment, and the

{

prompt completion of any plant modification 'needed to assure conformance

.s with the 00R Guidelines or NUREG-0588. A significant aspect of this' review u

is the timely: submittal 'of environmental qualification information by X

p_

the operating plantTlicensees to enable the staff to.coglete. its ~ review Lin accordance with the-Comission's Order.- The staff has a program g

{

' presently underway to reevaluate, using the 00R Guidelines and NUREG-

te environments that may exist following postuiated ' accidents. These-

accidents are loss of Coolant Accident and Main Steam Line Break l:

'f inside containment, and High Energy Line' Breaks inside and outside a

lj containment..

In this connection the~ licensee was requested by I&E-Bulletin 79-01B l:

of January 14, 1980 to provide a' detailed review of the environmental' i

qualification.of Class lE electrical equipment.

This review was to I) sinclude all equipment required to function under postulated accident

. {

ccnditions both inside and outside the primary containment, and

,a-recognize all conditions specified in the bulletin.

Evidence of qualification together with methods and justification, was requested.

,c Clarification was provided by supplemental information, briefings, and 4

in some cases, meetings with the. licensee.

Timely cogletion of the staff's: review of environmental' qualification of electrical equipment and timely cogletion of needed-modifications by the licensee is required to provide continuing reasonable assurance of public health f~

.and safety. Such cowletion -is dependent on the progt receipt.of a complete response by the licensee to the staff's requests for information.

l-However, the. licensee's' response, to date, is_ incoglete.

~

2 Therefore,- I have concluded that the public health, safety, and interest y.

i require.that-a firm schedule for the timely submission of all the
