On February 6th, a load reduction to 80% was completed to investigate Cl-inleakage f rom waterboxes "A" and "B".
The plant returned to full power on February 7th.
On February 13th, a load reduction to 80% was completed to sequentially check all waterboxes for C1 inleakage.
The plant returned to full power on February 16th.
On February 16th, a reactor trip resulted when an automatic turbine trip was initiated while performing D'J ground isolation procedures.
On February 17th, while at 30% power, and attempting to start a heater drain pump, the reactor and turbine were automatically tripped due to a high Heater Drain Tank level. The plant returned to full power on February 18th.
On February 27th, the reactor and turbine were manually tripped when P-2B steam generator feed pump tripped due to a failed low suction pressure switch.
The plant was returning to full power at the end of the month.
