SUBJECT:

ENVIRONMENTAL QUALIFICATION OF SAFETY-RELATED ELECTRICAL EQUIPMENT RE:

DRESDEN NUCLEAR POWER STATION, UNIT NO. 2

Reference:

Order for Modification of License Concerning the Environmental Qualification of Safety-Related Electrical Equipment, October 24, 1980.

This letter transmits the preliminary results of our review of environmental qualifications of safety-related electrical equipment at your facility.

This evaluation was based on your submittals received over the past months.

The facility license was modified by the referenced Order of October 24, 1980, to require that all safety-related electrical equipment be qualified to specified requirements not later than June 30, 1982.

In addition, the Order noted that a licensee is obligated to modify or replace inadequate equipment prOITlJtly.

The staff's review of your submittals has resulted in our identifying a number of potential equipment deficiencies involving a lack of proper documentation, inadequate justification of assumed environmental conditions following an accident, and/or inadequate environmental testing of equipment, such that conformance to the DOR guidelines, as required by the Order, cannot be demonstrated.

You are requested to review our identified defi-ciencies, and their ramifications, and provide us your overall finding regarding continued safe operation of your facility. Accordingly, in order to determine whether your license should be modified or suspended, you are required pursuant to 10 CFR 50.54(f ), to provide within 1-0 days of receipt of this letter, a written statement, signed under oath or affirmation sup-porting the safe operation of your facility, that takes into account the NRC staff's preliminary list of deficiencies.
