1 Docket No. 50-244 During monthly performance of procedure S-30.1 Safety Injection Valve Position Verification on June 3, 1980 at 0645 hours0.00747 days <br />0.179 hours <br />0.00107 weeks <br />2.454225e-4 months <br /> it was discovered that the circuit breaker for the A Loop Accumulator injection MOV-865 was in the ON position.

This is contrary to Technical Specification section 3.3.1.1.g which calls for removal of A.C. power for certain valves in the open position.

The valve position was verified as proper and the breaker was immediately returned to the required position.

Allbreakers listed in

'he S-30 series of verification procedures were reverified as in the correct position.

A review of the records shows that the breaker was placed in the correct position on May 21, 1980 per procedure 0-1.1, Plant Heatup from Cold Shutdown to Hot Shutdown.

This correct position was confirmed later the same day by Procedure 0-1.1C, Precritical Technical Specification Check Sheet.

The correct position was then verified later the same day by Procedure S-30.1, Safety Injection System Valve Position Verification.

The frequency of circuit breaker checks 'has been increased by amending procedure 0-9.1 Shift Relief Turnover-Auxiliary Operator to include checks by each shift.
