'Ihe unit began the month shutdown in hiode 3 for a scheduled maintenance outage.
i RCS heatup was stopped on July 1 o evaluate excess vibrations on 12A RCP. The RCS was cooled t
down to Mode 5 on July 3. Dalance shot was added and 12A RCP was placed back in operation.
l RCS heatup was commenced on July 14 and Mode 4 was entered at 1340. Mode 3 was entered at 00'O on July 15.
The reactor was taken critical at 0245 on July 18 and the generator was paralleled to the gri<l at 0956.
10096 (815 MWe) was reached at 0810 on July 20.
i Power was reduced to (X)96 (750 MWe) at 2200 on July 25 for nuclear instrument calibration. 'lhe unit returned to 10096 (825 MWe) at 0500 on July 26.
The unit ended the month at 10096 power (825 MWe).
