7/16 0615 - Started power ascension to 50%

7/16 1015 - Leveled Reactor power at 50%.

7/17 1540 - Reactor trip. Trio due to a hardware failure in CEAC 2 which resulted in random erroneous penalty factors being sent to the CPCs for DNDR and LPD.

7/18 0400 - CEAC 2 declared operable-following replacement of a faulty memory board and satisfactory retest.

7/18 2105 - Commenced Reactor startup.

7/22 0748 - Shutdown Circulating Water pumps C&D for suspected leakage of circulating water into condensate system.

7/22 0830 - Commenced reducing reactor power 7/22 1016 - Maintaining Reactor power at

'3%.

7/23 0534 - Started Reactor shutdown 7/23 0550 - Broke vacuum in condenser.

7/23 Investigating cause of high UNIDENTIFIED. LEAKAGE from RCS 7/23 Reactor trip breakers open, heat removal on Atmospheric Dump Valves, nonessential AFW for S/G feed, draining condenser hotwells.

7/24 0143 - Entered Mode 4.

7/24 0654 - Entered Mode 5 7/24 0705 - Stabilizing RCS temp at 200-205F.
