SDAR: CP-87-30 (INTERIM REPORT)

Gentlemen:

On July 1,1987, we verbally notified your Mr. H. S. Phillips of a deficiency involving errors in the seismic qualification report supplied by the vendor of the Roll-Away Missile Shields (RAMS). A preliminary review of these errors indicated that RAMS were overstressed for the designed seismic conditions detailed in the applicable specifications. This is an interim report of a potentially reportable item under the provisions of 10CFR50.55(e).

Our last report was logged TXX-6871, dated October 16, 1987.

We are continuing our evaluation of this issue and will submit our next report by February 5, 1988.

Very truly yours,

()). lo.
