VERMONT YANKEE NUCLEAR POWER STATION, LICENSE N0. OPR-28

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 cualifications 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 promptly.

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 fcilowing an accident, and/or inadequate environmental testing of equipment, su:h that conformance to the D0R 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 detennine whether your license should be modified or suspended, you are required pursuant to 10 CFR 50.54(f), to provide within 10 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 ac ~unt the NRC staff's preliminary list of deficiencies.

[

. The purpose of this statement is to provide the NRC with needed assurance, by the licensee, regarding the continued safdty of the facility until you can provide an item-by-item reevaluation in a detailed documented manner at a later date. A negative finding on your part concerning the safety of continued operation would result in a unit shutdown, and should be reported as a Licensee Event Report (LER) within twenty-four (24) hours of the deter-mination to the appropriate NRC Regional Office.

Include in the LER the actions you have taken for the immediate resolution of the matter. A copy of any such LER should be sent to the Director, Division of Licensing, Office of Nuclear Reactor Regulation.

Please submit a copy of your reply to us via telec :y.

Si ncerely, b /M Thomas M. Novak, Assistant Director for Operating Reactors Division of Licensing
