SEPTEMBER 1 2013 Shift began reducing load to approximately 440 GMWe to determine

' the cause of a rapid decrease in Circulating Water Flume level.

, Shift personnel discovered that the fill material in Cell 10 of Cooling Tower No. 5 had collapsed and clogged the screens at the tower.

4 SEPTEMBER 1 2140 Shift isolated and bypassed Cooling Tower No. 5 for inspection of the damaged cell.

SEPTEMBER 2 1514 Shift manually scrammed the reactor due to decreasing vacuum on the "A" Main Condenser as a result of "D" Waterbox becoming airbound.

SEPTEMBER 4 0033 Shift began withdrawing control rods for unit startup.

SEPTEMBER 4 0837 Shift brought the reactor critical. ,

1 SEPTEMBER 5 0017 Shift tied the unit to the grid and began ascension to maximum achievable thermal power. Fuel preconditioning measures were implemented to revent fuel degradation during ascension to  ;

maximum achievagle thermal power.

SEPTEMBER 5 2325 The unit attained maximum achievable thermal power.

SEPTEMBER 14 0855 Control Rod 42-19 drifted full-in when a half scram occurred during performance of Channel "B" Response Time Testing. The unit stabilized at approximately 615 GMWe, Maintenance personnel determined the control rod drive's Scram Solenoid Valves were leaking. Both valves were replaced.

SEPTEMBER 14 2345 Shift began reducing load to a I withdrawing Control Rod 42-19.pproximately 550 GMWe prior to SEPTEMBER 15 0108 Shift withdrew Control Rod 42-19 to Position 48.

SEPTEMBER 15 0200 The unit attained maximum achievable thermal power.

SEPTEMBER 22 0800 Shift began reducing load in preparation for a unit shutdown.

SEPTEMBER 23 0101 The unit entered the 12th Refueling Outage when Shift inserted a manual scram and a turbine trip.

SEPTEMBER 26 2320 Shift began core unload.

SEPTEMBER 30 2400 Personnel continued activities associated with the 12th Refueling Outage.
