SUBJECT:

REVIEW OF TOPICAL REPORTS 0:1 CLASS IE ELECTRICAL Afl0 CONTROL EQUIPfiErlT Additional information is needed to complete our review of Westinghouse Electric Corporation topical reports principally covering the capability of Class IE equipment to satisfy objectives of the IEEE 323-1971 Standard during normal and accident plant conditions.

These reports are identified in our July 31, 1978 letter to you.

In addition, we require additional infonnation to complete our review of a related report, WCAP-9157 entitled

" Environmental Qualification of Safety-Related Class IE Process Instru-mentation." The additional information requested is enclosed.

This additional information is needed by February 9,1979 to meet our review schedule.

If you cannot meet this date, please inform us within ten days after receipt of this letter of the date you plan to submit your response.

Sincerely,
