TO OPERATING LICENSE APPLICANTS
Gentlemen:
SUBJECT: QUALIFICATION OF SAFETY-RELATED ELECTRICAL EQUIPMENT
To ensure the adequacy of electrical equipment environmental qualification programs for those nuclear power plants required to satisfy the requirements set forth in the 1971 or 1974 version of IEEE Std. 323, the staff has developed additional guidance set forth in the NUREG-0588, "Interim Staff Position on Environmental qualification of Safety-Related Electrical Equipment". A "For Comment" copy of this document was mailed to you on January 9, 1980. Our letter of February 5, 1980. Our letter of February 5, 1980, noted the issuance of NUREG-0588 and described the staff plans to implement NUREG-0588 and IEEE Std. 323-1974.
Prior to the completion of our review of your application, it is necessary that we establish that you conform to the staff position or that you have used other equally acceptable methods. To assist us in that effort, you are requested to review your equipment qualification documentation (exclusive of seismic qualification considerations which are being addressed separately)
for each item of safety-related electrical equipment to identify the degree to which your qualification program complies with the staff's position described in NUREG-0588. Where there are deviations, you should provide the basis for concluding that your program demonstrates the item in question is qualified for its service conditions. Should you conclude that your qualification program does not adequately demonstrate that an item is qualified for its service conditions, that item should be requalified in accordance with the position described in NUREG-0588 and the implementation guidance provided to you in our letter dated February 5, 1980.
You should document, in a separate report or in your FSAR, the results of your review for each item of safety-related electrical equipment. As a part of this documentation, you are requested to provide a tabular listing of all such equipment and appropriate qualification-related data for each item in accordance with the enclosure, "Example Table - Environmental Qualification of Electrical Equipment". This table should include all equipment located both inside and outside containment, including balance-of-plant equipment and equipment supplied by your nuclear steam system supplier. This table will assist us in our audit of your qualification review documentation.FEB 21 1980

Please advise us of your schedule for completing this review
Sincerely,
