O UNITED STATES OF AMERICA NUCLEAR REGULATORY COMMISSION In the Matter of

BALTIMORE GAS AND ELECTRIC COMPANY
)
Docket Nos. 50-317 (Calvert Cliffs Nuclear Power
)
and 50-318 Plant, Unit Nos. 1 and 2)
)
i REVISED ORDER FOR MODIFICATION OF LICENSE I.
Baltimore Gas and Electric Company (licensee) is the holder of License Nos.
I DPR-53 and DPR-69 which authorizes the operation of the Calvert Ci.'fs Nuclear Power Plant, Unit Nos.1 and 2 at steady state reactor power levels not in excess of 2700 megawatts thermal (rated power).
The facilities consists of two Pressurized Water Reactors located at the licensee's site in Calvert County, Maryland, II.
g, On November 4,1977, the Union of Concerned Scientists (UCS) filed with the Commission a " Petition for Emergency and Remedial Relief."
The 4
f 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 Comnission 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 reaffirned its April 13, 1978 decision l
l A010150g
l I
regarding the possible shutdown of operating reactors.
However, the Commission (s May 23, 1980 decision directed licensees and the NRC staff i
i to undertake certain actions.
With respect to environmental qualification of safety-related electrical j
equipment, the Commission determined that the provisions of the two staff documents - the Division of Operating Reactors " Guidelines for Evaluating Environmental Qualification of Class lE Electrical Equipment i
in Operating Reactors" (00R 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-4 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-058,8 i
i will apply."
The Commission also directed the staff to complete its I
review of the information sought from licensees by Bulletin 79-018 and to complete its review of environmental qualification of safety-related i
1 electrical equipment in all operating plants, including the publication of Safety Evaluation Reports, by February 1,1981.
The Commission 1
i 1-Bulletin 79-OlB was not'sent to licensees for plants under review as part of the staffls Systematic Evaluation Program.
The information sought by Bulletin 79-OlB was requested from these licensees by a series of letters and a etings 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 DDR Guidelines or NUREG-0588." The Commission requested the staff to, " keep the Commission and the public apprised of any further findings of incomplete environmental qualification of safety-related electrical equipment, along with corrective actions taken or planned,"
and requested the staff to provide bi-mor.thly progress reports to t e Commission.
The Commission further directed the staff to add certain documentation
- cauirements to each license after the specific requirements were approved by the Commission.
The Commission also pointed out that the various deadlines imposed in its Order, "do not excuse a licensee from the obligat'.on to modify or replace inadequate equipment promptly."
III.
P The information deseloped during 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 prompt completion of any plant modification needed to assure conformance wi th the D0R 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 couplete its review in accordance with the Commission /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
_4_
to environments that may exist following postulated accidents.
These accidents are Loss of Coolant 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 1E electrical equipment.
This review was to include all equipment required to function under postulated i
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 staffls review of environmental qualification of electrical equipment and timely canpletion 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 for infonnation.
However, the licensee ls response, to date, is incanplete.
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.
