DOCKET NO. 50-446 G0ULD BATTERY RACKS TRANSVERSE BRACING SDAR: CP-86-46 (INTERIM REPORT)
Dear Mr. Johnson:
On June 11, 1986, we verbally notified your Mr. C. Hale of a deficiency involving a design change to vendor supplied equipment being made without formal evaluation by the vendor. 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-4900, dated July 11, 1986.
/ The specific issue involves a design change to Gould battery racks which
( revises the transverse bracing mounting bolt design from a two-bolt to a one-bolt configuration. This issue is applicable to all Class lE battery racks in Unit 2. Currently, the technical disposition of the nonconformance and resolution of the associated design changes are in preparation. Completion of these activities is currently scheduled for September 30, 1986.
We are continuing our evaluation and anticipate submitting our next report by October 21, 1986.
Very truly yours, flA$f g9QQgy$I8 6 W. G. Counsil S
