SUMMARY

OF OPERATING EXPERIENCE j

dpril 1994 The unit began the month at 100% reactor power.

Reactor power was reduced on April 24,1994 at 1853 due to the main turbine intercept valve shutting. The valves shut when 4 KV bus #21 was lost during testing of the Safety Related Voltage Regulators. Reactor power was reduced to approximately 95% at 1908. The unit was returned to 100% power at 2200 on April 24,1994 and remained there through the end of the month.
