SUBJECT:
OUTAGE GREATER THAN 2 DAYS On September 6,1988, at 6:06 a.m. (CDT) the reactor scramed from 100 percent power. The main generator tripped because of a loss of a normal station transformer (believed to have been caused by a cat crawling into the transformer).
This resulted in a turbine' trip and reactor scram. Although the vessel water '.
level does not appear to 5 ave dropped to the HPCS and RCIC initiation setpoint (Level 2), the HPCS and RCIC pumps started and injected briefly. as occurred
- during the reactor trip of August 25, 1988 (PN0-IV-88-70). Howe a r, unlike the August 25 trip, there was no indication of backleakage into the HPCS injection
The licensee secured from the NOUE at 7:30 a.m. All station transformer transfers, from normal to preferred, occurred as expected. Reactor pressure is being controlled by the bypass valves and level maintained utilizing one reactor feed pump and the startup regulating valve. Reactor shutdown is expected to exceed 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
