DOCKET NOS. 50-445 AND 50-446 DEVIATIONS IN G0ULD BATTERY RACK DIMENSIONS SDAR: CP-86-76 (INTERIM REPORT)

Gentlemen:

On October 21, 1986, we verbally notified your Mr. I. Barnes of a deficiency involving the configuration and dimensions of Gould Battery Racks deviating from drawing requirements. This is an interim report of a potentially reportable item under the provisions of 10CFR50.55(e). We have submitted an interim report logged TXX-6110, dated November 20, 1986. On April 22, 1987, we aisc verbally requested and received from the NRC an extension until May 1, 1987 to respond to this issue.

1 Class 1E battery racks for Trains A and B, which were designed and fabricated by Gould, were found to have configurations and dimensions which deviated from the vendor design drawings. These deviations could result in violation of battery cell spacing requirements for Class IE batteries. Our review has determined that the conditions are applicable to Units 1 and 2.

Currently our evaluation is in the final stage of review. Our next report will be submitted by June 5,1987.

Very truly yours,

'IA W. G. Counsil RWH/gj c - Mr. E. H. Johnson - Region IV Mr. D. L. Kelley, RI - Region IV Mr. H. S. Phillips, RI - Region IV 1
