SALEM UNIT 2 OPERATIONS

SUMMARY

REPORT AUGUST 1983 Unit'No. 2 began'the month ~in a power escalation following a trip of the reactor which occurred on July 29, 1983. . On August 1, during the power escalation, No. 2 Reactor tripped due to a spurious actuation of 2A Safeguards -Equipment Controller - (SEC) .' The SEC actuation caused a loss of-the equipment associated with the 2A Vital Bus. The-rod control system alternate power-supply failed to supply control power to.two control rod banks following swap-over from the deenergized 2A Vital Bus. This caused the control banks to fall into the core,

- tripping the reactor on a nuclear instrument negative rate trip.

A reactor startup was commenced on August 2, and-the unit was operating at-full-power on August 6. The majority of reactor zero power. physics and power escalation testing was completed.between

August 1 and August 11. Unit No. 2 continued to operate at full power 1

until the trip.of Unit No. 1 on August 11, due to the accumulation of excessive grass on the Circulator Water Screens. Following.the trip j of Unit No. 1, grass-began building up on the Unit No. 2 Circulating i Water Screens, causing a loss of five of the six circulators. Unit 4

-load was rapidly reduced, the generator was unloaded, and the

generator breakers were opened. The turbine wasJtripped'while reactor power was above the P-7 permissive setpoint resulting in an automatic

~ reactor trip.

Following the reactor trip of August 11, the decision was made to cool

.down to facilitate the replacement of the failed Intermediate Range

-Channel N35 Detector.

During the cooldown for repairs to Intermediate Range N35, the master controller for. pressurizer pressure failed high. .This caused both pressurizer? spray valves to fully open, resulting-in a rapid decrease of pressurizer pressure, which initiated a ' safety injection on low pressurizer pressure.

The reactor was again critical on August 16, and operating at full

,  : power on August 17. Unit'No. 2 continued to operate at full power until August 19 when the discovery of a hydrogen leak into the generator istator cooling water system forced a shutdown of the unit.-

Subsequent investigation revealed that there were six leaks on the general internal "T" connections where cooling water lines from the stator tie into the header. The cause of the leaks appears to be due

.to vibration fatigue caused by a' resonance frequency problem.

Additional' resonance-frequency. testing disclosed several loosened phase leads on the exciter end of the generator. Unit No. 2 remained shutdown through the end of August,.as repairs to the generator

. continued. Unit No. 2 is currently scheduled to return to power on September' 26,.1983.
