The reactor was operating in the end 6f cycle 1 coastdcv:n:
Reactor power was decreased to extend the cycle to October 5,1979 pending itRC approval.
Amendment 15 to fiPF-4 was approved.
Subsequent analysis indicated that reactor power could be increased back to maxiinum attainable.
Reac;.or power was increased to approximately 00%.
79-16 (B) (4)
Reactor power was decreased to establish the required conditions for turbine valve testing.
The required testing was completed and reactor power was escalated to 80%.
The reactor was not shutdorm.
79-17 t.
(3)
The 5th point heater drain cooler dump valve LCV.iD-1280 began to cycle due to a tube rupture inside the cooler The leakage was nore than the capability of the drain valves causing extraction steam condensate to back up into the Lth point heater to the turbine trip setpoint.
This resulted in an automatic Reactor Turbine Generator trip.
The heat 7r drain cooler tubes will be replaced during the current cutage.
79-18 (C) (4)
Comenced the scheduled refueling outage at 0900 Septeirbar 25, 1979.
