APRIL 4, 0410 Commenced reactor power increase to 80% following unsuccessful attempts at locating leak in P-116 water box.

APRIL 5, 2030 Comoleted heat treatment. Helium leak checking of P-116 water box did not reveal any leaks. Ten tubes were plugged as a preventative measure and no conductivity increase was noted. Commenced reactor power increase to 100%.

APRIL 5, 2045 Completed turbine stop and governor valve testing.

APRIL 6, 0553 Reactor power at 100% and turbine load at 1130 MWe gross.

APRIL 13, 1810 Decreased reactor power to 90% and turbine load to 1050 MWe gross to perform turbine stop and governor valve testing.
