License No. DPR-36 (Docket No. 50-309)

Dear Sir:

Pursuant to the requirements of Technical Specification 5.9.1.6, the Maine Yankee Atomic Power Company hereby submits the following report.

On May 23, 1979 during a review of calibration values prior to performing the RFS surveillance, it was discovered that incorrect setpoints had been utilized for the steam generator low pressure trip bistables.

Instead of the required 485 psig setpoint, values of approximately 415 psig had been inserted.

At the time of discovery the plant was in the cold shutdown condition. The correct setpoints were immediately installed and the channel calibration tests were performed to verify channel operability.

Preliminary review indicates that the error in the setpoint has no impact on the limiting transient analyzed in the safety analysis.

A more detailed review of the effect upon less limiting cases will be completed within two weeks to confirm this result.

Very truly yours, MAINE YANKEE ATOMIC POWER COMPANY h//*/r f,
