SDAR: CP-86-45 (INTERIM REPORT) *

Dear Mr. Johnson:

On June 6,1986, we verbally notified your Mr. T. F. Westerman of a possible deficiency involving the interaction of non-seismic Category I structures and components with seismic Category I structures. This is an interim report of a potentially reportable item under the provision of 10CFR50.55(e). We have submitted interim reports logged TXX-4893 and TXX-4979 dated July 3,1986, and August 22, 1986, respectively.

The primary means at CPSES of ensuring that non-seismic Category I equipment does not affect seismic Category I equipment is to ensure that the non-seismic Category I equipment is properly mounted and anchored. This practice is common throughout the industry and was the intent of our FSAR commitment. It is also consistent with the conclusions of the NRC staff in NUREG 1030,

" Seismic Qualification of Equipment in Operating Nuclear Power Plants." We are examining our commitment and practices in detail to ensure that they are clear, precise, and provide adequate assurance of safety.

We anticipate submitting our next report by December 3, 1986.

I Very truly yours, N
