-UNIT 1

NARRATIVE SIDetARY OF OPERATIONS January,' 1987 There were four unit shutdowns during the' month of January.. The first.

unit shutdown occurred on January 8 when a turbine trip was initiated manually due to~an air-leak on an air supply lline to a main steam isolation valve (MSIV)..The air line to the MSIV had moved into contact with a rigid.

tubing support due to thermal expansion. This caused the air supply line

-to crack and leak. The air line was replaced and the tubing support notched so that it would not be in contact with the air line.

The second unit shutdown occurred on January 9 when the unit was ramping up from the first shutdown of the month and the reactor tripped due to lo-lo steam generator level following.a manual tripping of the main turbine.

The turbine was tripped because both steam generator feed pumps (SGFPs) had tripped ~due to low suction pressure. This reactor trip was caused by personnel error in that the operators and shift supervisor failed to adequately'_ monitor the SGFP suction pressure and take appropriate action to prevent the'SGFP pressure from decreasing below the trip setpoint for SGFPs.

The appropriate procedures have been revised to remind operators to monitor SGFP pressure.

The third unit shutdown occurred on January 13 when-the unit was ramped down and the generator taken off-line to repair a leaking turbine interface valve.

The valve was replaced and the unit returned to power operation.

The fourth unit shutdown ~ occurred on January 22 when the reactor tripped.due to high flux rate as indicated by nuclear instrumentation channels N41 and N42. The lA inverter which supplies power-to N41 failed

-while N42 was in test. for surveillance. This resulted in the two-out-of-

~

four coincidence for a high flux rate reactor trip. The testing on N42 was completed and N42 was returned to service. The backup power supply for N41 was placed in service and the unit returned to power operation.

The following major safety-related maintenance was performed in the month of January:

1.-

An air leak was repaired on an MSIV-air supply line.

2.

The 1A inverter was tested and four blown fuses were replaced. No cause for the blown fuses could be found. The inverter was returned to service.

3.

Miscellaneous corrective and preventive maintenance was performed on diesel generators.
