3 REVISED ORDER FOR MODIFICATION OF LICENSE I.
Connecticut Light and Power, the Hartford Electric Light Company, Western Massachusetts Electric Company and Northeast Nuclear Energy Company (the licensees) are the holders of Provisional Operating License No. DPR-21, which authorizes operation of the Millstone Nuclear Power Station, Unit No.1 at steady-state reactor power levels not in excess of 2011 megawatts thermal (rated power). The f acility consists of a boiling water reactor located at the licensee's site in Waterford, Connecticut.

On November 4,1977, the Union of Concerned Scientists (UCS) filed with tb 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 i3,1978 (7 NRC 400), the Comission denied certain aspects of the petition and, with respect to other aspects, ordered the NRC staff to take severt.. related actions. UCS filed a Petiticn for Reconsideration on May 2,1978. By Memorandum and Order, dated May 23, 1980, the Comission reaffirmed its April 13, 1978 decision 8011060 g39
--2 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 j
staff documents - the Division of Operating Reactors " Guidelines for Evaluating Environmental Qualification of Class lE Electrical Equipment in Operating Reactors" (DOR 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 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 Lormission 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 1
review of the information sought from licensees by Bulletin 79-01B and to complete its review of environmental quelification of safety-related electrical equipment in all operating plants, including the publication of Safety Evaluatior. Reports, by February 1,1981.
The Commission 1 Bulletin 79-OlB was not sent to licensees for plants under review as The information part of the staff's Systematic Evaluation Program.
sought by Bulletin 79-01B was requested f rom these licensees by a series of letters and meetings during the months of February and March, 1980.

7 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 D0R Guidelines or NUREG-0588."
The Comission requested the staff to, " keep the Comission and the pLblic apprised of any further findings o' inconplete 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 Comission further directed the staff to add certain documentation requirements to each license af ter the specific requirements were approved by the Comission. The Comission also pointed out that the various deadlines imposed in.ts Order, "do not' excuse a licensee from the obligation to modify or replace inadequate equipment promptly."
111.
The information developed during this proceeding emphasizes the importance of adequate documentation, the prompt completion of the review of envire mental qualification of saf ety-related electrical equipment, and the pror.pt conpletion 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 undemy to reevaluate, using the DDR Guidelines and NUREG-0588, the qualifications of saf ety-related electrical equipment exposed
to environments that say exist following postulated acrilents. These accidents are Loss of Coolant Accident and Main Steam Line Break inside containment, and High Energy Line Breaks inside and outside contai nment.
In 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 corplete package, including justification for methods used, was requested.
Clarification was provided by supplemental information, briefings, and in some cases, meetings with the licensee.
Timely completion of the staff's 4
review of environmental qualification of electrical equipment and timely completion of needed modifications 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 licensee to the staff's requests f or information. However, the licensee's response, to date, is incomplete.
Therefore, I nave concluded that the public health, safety, and interest require that a firm schedule f ar the timely submission of all the information previously req.iested by the staf f should be established by Order ef fective immediately.

IV.
l Accordingly, pursuant to the Atomic Energy Act of 1954, as amended, and the Comission's regulations in 10 CFR Parts 2 and 50, IT IS ORDERED THAT EFFECTIVE IMMEDIATELY Provisional Operating License No. OPR-21 is hereby amended to add the following provisions:
"Information which fully.and completely 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 1,1980."
An earlier response.f s encouraged to facilitate staff review and issuance of the safety evaluation report. The iicensee or any person whose interert 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 addressec' to the Directnr, Office of Nuclear Reactor Regulation, U.S. Nuclear Regulatory Lomission, Washington, D. C.
20555. A copy of the request shculd also be sent to the Executive Legal Director, U. S. Nuclear Regulatory Comission, Washington, D. C.
20555, and to Day, Berry & Howard, Couns?lors at Law, One Constitution Plaza, Hartford, Connecticut 06103, attorney for the licensee.
If a hearing is held concerning t'his Order, the issue to be considered at the hearing shall be whether the license should be modified to require submission of.r. formation 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 60070, September 11,1980).
