)
ORDER FOR MODIFICATION OF LICENSES I.
=
Baltimore Gas and Electric Company (licensee) is the holder of License Nos.
DPR-53 and DPR-69 which authorize the operation of the Calvert Cliffs 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
~
consist of two Pressurized Water Reactors lccated at the licensee's site in Calvert County, Maryland.
II.
On November 4,1977, the Union of Concerned Scientists (UCS) filed with the Commission a " Petition for Er.ergency 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 Commission 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 Commissicn reaffirmed its April 13,197P decision 9

' 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 staff documents - the Division of Operating Reactors " Guidelines for Evaluating Environmental Qualification of Class lE Electrical Equipment in Operating Reactors" (D0R Guidelines) and NUREG-0588, " Interim Staff Position on Environmental Qualification of Safety-Related Electrical Equipinent," 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 Commission 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 informati a sought from licensees by Bulletin 79-01B and to complete its review of envircnmental qualification of safety-related electrical equipment in all operating plants, including the publication of Safety Evaluation Reports, by February 1,1981.
The Commission 1
Sulletin 79-018 was not sent to licensees for plants under review as part of the staff's Systematic Evaluation Program.
The information sought by Culletin 79-01B was requested from these licensees by a series of letters and meetings dqring the months of February and March, 1983.

. 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 I
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-monthly progress reports to the Commission.
The Commission further directed the staff to add certain documentation requirements 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 obligation to modify or replace inadequate equipment promptly."
III.
The information developed 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 confornance with the DDR Guidelines or NUREG-Cood.
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 Commission's Order.
The staff has a program presently underway to reevaluate, using the D0R Guidelines and f!UREG-0588, the qualifications of safety-related electrical equipment exposed i
e o
N, 4-to environments that may exist following postulatad 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 79-018 dated January 14, 1980 to provide a detailed review of the environ-mental qualification of Class lE electrical equipment.
This review was to include cll equipment required to function under postulated 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.
Tintely completion of the staff's ' review of environmental qualification of electrical equipment and tinely 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 for information.
However, the licensee's response, to date, is incomplete.
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 i imediately.
