MARCH 1 1035 Shift began reducing load to approximately 535 GMWe to perform

Control Rod Drive Exercises on selected control rod drives. The i servo strainers on Main Turbine Control Valves Nos.1, 2, and 4 were replaced to inspect for ci(TCVs)ogging.

MARCH 1 1950 Shift began ascension to maximum achievable thermal power.

j MARCH 2 0305 The unit attained maximum achievable thermal power.

MARCH 8 2004 Shift began reducing load to approximately 545 GMWe to perform

Control Rod Drive Exercises on selected control rod drives.

A faulty relay co il

resulted in a blown Group 2 logic power fuse. The outboard Group 2 isolation valves closed per design, u The fuse and relay coil,were replaced,pon loss of logic power.and the Gro

signal was reset.

MARCH 9 1702 Shift began ascension to maximum achievable thermal power. Fuel

preconditioning measures were implemented to prevent fuel degradation during ascension.

l j MARCH 9 2140 The unit attained maximum achievable thermal power.

! MARCH 16 0145 Shift began reducing load to approximately 400 GMWe to remove ,

l Circulating Water Pump "B" from service for pre-outage l maintenance on the pump motor.

When the turbine was shut down, l reactor pressure increased and exceeded the high pressure scram setpoint, causing an automatic reactor shutdown, per design.

The Main Turbine operating procedure did not require reactor i pressure to be decreased to provide a sufficient margin between actual pressure and the high pressure scram setpoint prior to tripping the Main Turbine.

MARCH 26 2210 Shift began core unload.

I MARCH 30 1811 Shift completed core unload.
