COMANCHE PEAK STEAM ELECTRIC STATION (CPSES)

DOCKET NOS. 50-145 AND 50-446 SEISMIC AIR GAP DESIGN ADEQUACY SDAR: CP-86-55 Gentlemen:

On August 14, 1986, we verbally notified your Mr. I. Barnes of a deficiency involving the seismic air gap design adequacy between the Auxiliary Building and Units 1 and 2 Containment Buildings. This is an interim report of a potentially reportable item under the provisions of 10CFR50.55(e). Our last interim report was logged TXX-6107, dated November 21, 1986.

The evaluation of the refined calculations indicating acceptability of the existing gap (as noted in our previous reports) is continuing in conjunction with the validation of the Seismic Category I Building analysis. The results of this composite evaluation are needed to complete our assessment of the impact of this issue upon the safety of plant operations. The validation 4

program is currently scheduled for completion by June 1,1987.

Our next report on this issue will be submitted no later than July 8, 1987.

Very truly yours, W. G. Counsil
