BEARD TELEPHONE: (912) 367-7781 x2878 MAY l 0000 Shift continued maintaining 95% of rated thermal power with the "B" Condensate Pump out of service due to a request from the control center that activities which require a load reduction not be performed until maintaining system load capacity was not as critical.

MAY 2 2228 shift began reducing load to approximately 525 GMWe to return the "B" Condensate Pump to service.

MAY 3 0236 Shift began ascending to rated thermal power.

MAY 3 0427 The unit attained rated thermal power.

MAY 17 1955 The "A" Reactor feed Pump tripped due to low bearing oil pressure while shift personnel were swapping oil pumps in accordance with the weekly surveillance on the Reactor feed Pumps. The Reactor Recirculation Pumps ran back to the No.2 Speed Limiter, as designed, reducing unit load to approximately 500 GMWe. Shift personnel performed Turbine Control Valve and Turbine Stop Valve Testing while at reduced load.

MAY 18 0115 The "A" Reactor Feed Pump was returned to service and ascension to rated thermal power was initiated.

MAY 18 0535 The unit attained rated thermal power.

MAY 31 2400 Shift continued maintaining rated thermal power.
