SUBJECT:

COMANCHE PEAK STEAM ELECTRIC STATION (CPSES)

DOCKET NOS 50-445 AND 50-446 AUXILIARY FEEDWATER PUMP MOTOR FANS SDAR: CP-87-33 (INTERIM REPORT)

Gentlemen:

On July 8,1987, we verbally notified your Mr. R. F. Warnick of a deficiency involving the rotational direction of the auxiliary feedwater pump motor cooling fans for Units 1 and 2. This is an interim report of a potentially reportable item under the provisions of 10CFR50.55(e).

During startup examination of the Unit 2 auxiliary feedwater pump assembly, the rotational direction of the motor cooling fans was determined to be opposite from the design requirements. Similar condition exists in the Unit 1 auxiliary feedwater pump motor cooling fans.

Further evaluation is required to determine the impact of these conditions.

We will submit the next report by October 7, 1987.

Very truly yours, MGud W. G. Counsil MCP/gj c - Mr. R. D. Martin, Region IV Resident Inspectors, CPSES (3) 8708120026 870B07 ADDCK 0500 5 gDR
