SUBJECT:
Environmental Qualification of Electrical Equipment (Dresden Nuclear Power Station un,it Nos. 1 and 2)
This letter transmits orders which*require information to support the environmental qualification of safety related electr1ca1 equipment at Dresden Nuclear Power Station Unit Nos. 1 and 2.
The Commission's Memorandum and Order of May 23, 1980 addresses safety related electrical equipment exposed to a harsh environment, inside or outside containment, resulting from an accident. The Orders require that all such equipment in operating reactors be fully qualified by
- June 30. 1982.
To complete this objective, you are required to submit, by November 1, 1980, all information to support a safety evaluation of the aforemen-tioned equipment.
If your facilities had an established commitment date before November 1, 1980, it is fully expected that your submittals will be not later than that commitment date. If your facilities' commitment date is past without a complete submittal~ it is strongly_recomtt~nded that actions be expedited since they have already impacted the staff review schedule.
Briefings were held with all interested licensees during the week of July 17, 1980.
Enforcew~nt actions relative to these Orders were dis-cussed during these briefings.
Sincerely,

7590-01 Commonwealth Edison Company (the licensee) is the holder of Facility Operating License No. DPR-2, w.hich authorizes the operation of the Dresden Nuclear Power Sta ti on, Unit No. 1 at steady-state reactor power 1 evel s not in excess of 700 megawatts thermal (rated power).
The facility consists of a boiling water reactor "located at the licensee's site in Grundy County, Illinois.
I I.
On November 4, 1977, the Union of Concerned Scientists (UCS) filed with
- the Coiilmi s si on a 11Peti ti on for Emergency and Remedi a 1. 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, l Y78 ( 7 NRC 400), the Commission denied certain aspects of the petition and, with respect to other aspects, o~dered the NRC staff to take several r~lated actions.
UCS filed a Petition for Reconsideration on May 2~ 1978.* By Memorandum and Order,
- dated May23, 198C., the Commissidri reaffirmed its April 13; 1978 decision
- 2..;
regarding the. possible shutdown of operating reactors.
However, the I
Commission's May 23, 1980 d~cision directed licensees and *the NRc* staff
. to undertake c:ertai n 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*.

7590-01 Commonwealth Edison Company.(the licensee) is the holder of Provisional Operating License No.
DPR-19~.which authoriies.the operation of the Dresden Nuclear Power Station; Unit No. 2 at steady-state reactor power levels not i.n excess of 2527 megawatts thermal (rated power).
The facility consists of.
a boiling water reactor located at the licensee's site in Grundy County, Illinois.
I I.
On Nov~mber 4, 1977, the Union of Concerned Scientists (UCS} filed with the Commission a "Petition for Emergency and Remedial Relief.'1 The petition sought action in two areas:
fire protection for ele*ctrical' cables, and environmental qualification of electrical components.
By Memorandum and Order dated April 13, 1978 (7 NRC 4*00), the Commission denied certain aspects of the petition and, with respect to other aspects, ordered the NRC $taff to take several related actions.
UCS fil~d a Petition for Reccinsideration o~ May 2, 1978.
By Memorandum and Order, dated May 23, 1980, the Commission reaffirmed its April 13, 1978 decision

- 2 regarding the possible shutdown of. operating reactors.** However, the Commission's May 23, 1980 decision directed licensees and the NRC staff to undertake certainactions.'
- 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 Envir6nme~ta1,Qualif~cation of Class lE El~ctrical Equipment*
in Operating Reactors" (DOR Gui:deli~es) and NUREG-0588, Interim Staff Position on Environmental Qualification of Safety-Related Electrical Equipment, 11 December 1979 "form the requirements which licensees and applicants must meet in.order to satisfy those aspects of 10 CFR Part SO,. Appendix A GeneralDesign Criterion (GDC~4), which relate to envi-rQnmental qual ificatibn of safety'.:.related electric~l equipment. II, The Commission directed, _for replacement parts in operating pl ants, "unless
. there are sound r_easons to the contrary, the 1974 standard in NUREG-0588 will apply."** The Commission also airected the staff to complete its 1
review O*f the information sought from licensees by Bulletin. 79-0lB. and
.*. to complete its review of envfronmental qua 1 i fi ca ti on of safety-related
. electrical equipment in all operating plant~. in~luding the publication of Safety Eva.l uati on Reports, by Feoruary 1, 1981.. *.The Cammi ssi on 1
- . Bul 1 eti n 79-01 B was not senf to 1 i censees. for pl ants under review as part of the*staff 1 s Systematic Evaluation Program.
the information sought by Bulletin 79-018 was requested from these licensees by a series of letters a11d meetings curing *the months *o*f Fe*brua*ry and*March, 1980.
imposed a deadline that,. "by.no later than June 30, 1982, all safety~
relat.ed electrical equipment in _all operating plants shall be qualified to the DOR Guidelines or NUREG-0588.
11 The Commission requested the staff to, 11keep the Commission and the public apprised of any further findings of incomplete environmental q~alification of safety-related electrical equipment, along with corrective actions taken or planned,"
and requested the* staff to provide bi-monthly progress reports to the Commission *
. The Commission.further directed the staff to add certain documentation*.
requirements to ~ach license after the sp~cific requirements wer~ approv~d by the Commission.
The Commission also pointed out that the various*
deadlines impo~ed in its O~der,."do not e~cuse a licens~e from the obligation to modify or replace 1nadequateequipment promptly.".
III.
The information developed during this proceeding emphasizes the importance of adequate documentation, the prompt completion of the review of environ-men.ta l qualification of safety-related electrical equipment, and the prompt completion of any pl ant modi f i ca ti on needed to assure confonnance with the DOR Guidelines or NUREG-0588 *. A significant aspect Of this review is the timely submittal of environmental qualification infonnation by the operating plant licensees to enable the staff to complete.its review in accordance with tne Commission's Order.
The staff tias a program presently underway to reevaluate,*using tne DOR Guidelines and NUREG-CJ52~, tne qualifications of safety-.:--elated electrical equipment exposec

. to environments.that may_ exist following~postulated accidents. These accidents are Loss of Coola~t Accident and Main Steam Line Break inside containment; and.High EnergyLine Breaks inside and outside containment *.
In this *connection the licensee was requested by our letter of March 6, 1980, as modified by our letter of March 28, 1980, to proviae information o*n.emergency procedures and safety related systems.
The 1 icensee was*
requested to define and provide the basis f6r the hostile environment,
. inside and outside contain~ent. This hostil~ environment would then be used, by the licensee, in the determination of unqualified equipm.ent.
A complete package, including justification for methods used, was requested.
Clarificatlon was provided by supplemental information, briefings, ana; in some cases, meetings with the licensee. Timely completion of the staff's*
- review of environmental qualification of electrical equipment and timely
- completion of needed rnoaifications by the licensee is required to provide*
continuing reasonable. assurance of public health and *safety.
Such completion is dependent on the prompt receipt of a complete response by the l.icensee to the staff's.requests for information.
However, the licensee 1 s response,*
to date, i~ incomplete.
Therefore, I have concluded that the public health, safety, and interest required that a firm schedule-for the timely submissi~n of all the informa-tion previously req*uested by the staff should be established by Order effective immedi~tely. *
