In preparation for planned maintenance of … In preparation for planned maintenance of 12 Diesel Driven Cooling Water Pump (Train A), 121 Cooling Water Pump was aligned as a safeguards replacement pump per plant procedures. Maintenance steps were then completed to a point allowing testing and 12 DDCLP was restored. The Operations procedure steps to enter the Cooling Water LCO 3.7.8 Condition A and realign 121 CL Pump away from being a safeguards replacement were missed and permission was granted to perform testing. 12 DDCLP was locally started per the PM and then tripped as directed from rated speed at 1513. The pump trip resulted in a cooling water pressure transient that automatically started 121 CLP and is reportable under 10CFR 50.72(b)(3) as an unplanned safety related system actuation. 121 CLP operated normally and there were no adverse plant effects from the transient.</br>During the investigation of the automatic start, it was recognized that with 121 CLP still aligned as a safeguards replacement and 12 DDCLP running locally, a Safety Injection signal and start of 22 Diesel Driven Cooling Water Pump (Train B) would result in 121 CLP trip. LCO 3.7.8 Condition A was entered for one safeguards pump OOS and 121 CLP was returned to OPERABLE status at 1613. 121 Cooling Water Pump was shut down and returned to standby at 1936.</br>Maintenance activities and testing for 12 DDCLP have been suspended pending investigation and corrective actions. 121 CLP remains aligned as a safeguards replacement and both cooling water headers have operable safeguards pumps.</br>The licensee notified the NRC Resident Inspector.</br>* * * * UPDATE AT 1700 EDT ON 03/20/09 FROM TYLER GREENFIELD TO S.
