10CFR21 SUBSTANTIAL SAFETY HAZARD EVALUATION INTERIM REPORT

DESCRIPTION OF DEVIATION:

A safety related W2 Control Switch, procured from Westinghouse, did not operate satisfactorily when drawn from stock to be installed in the Main Control Board for 1C2 Safety Injection Pump. The switch did work properly before installation in the Main Control Board position. However, subsequent to installation the switch mechanism would bind and would not spring return to the "after close" or "after trip" positions. The switch is expected to function properly in both applications.

REFERENCE DOCUMENTS:

Rochester Gas & Electric Purchase Order NQ-15824-A-JW

DATE WHEN EVALUATION WILL BE COMPLETED:

The W2 Control Switch has been returned to Westinghouse for a failure mode assessment and a potential 10 CFR Part 21 evaluation to determine if the switch was deficient at the time of manufacturing. It is estimated that this evaluation will be completed by October 1, 1999.
