JOSEPH M. FARLEY NUCLEAR PLANT UNIT 1 NARRATIVE

SUMMARY

OF OPERATIONS May 1991 The cycle 10-11 refueling outage continued into the month of May.

Power operation began at 2314 on 5-19-91.

The generator was taken off. ne at 1231 on 5-20-91 to perform a turbine overspeed trip test.

The unit returned to power operation at 1456 on 5-20-91.

At 0050 on 5-24-91, with the unit operating at approximately 78 per cent power, a reactor trip occurred when the two-out-of-three coincidence was satisfied for over-temperature-delta-temperature (0 TDT). Work in progress on pressurizer pressure instrument P1456 required channel 2 of OTDT to be placed in the tripped condition. At the same time, a portable instrument was attached to a resistance temperature detector (RTD) in channel 1 for an unrelated test. Attaching the test instrument to the channel 1 RTD caused a second channel of 0 TDT to enter the tripped condition and the coincidence for a reactor trip was satisfied.

The unit returned to power operation at 0413 on 5-25-91.

The following major safety-related maintenance was performed during the month:

1.

The number one seal on the IB reactor coolant pump was inspected.

2.

Miscellaneous corrective and preventive maintenance was performed on the diesel generators.
