April 7, 0525 Stopped WCW pump 3P-120. W CW surge tank was pressurized to the discharge head of the TpCW pur.ps as a result of a mispositioned valve and the removal of an automatic control feature. 'Ihe tank bottom bowed and all anchor bolts parted.

April 7, 1300 mtered Mode 5 and comenced outage activities consistent with NRC approval for return to Mode 2 and power operation.

April 18 2034 Placed W CW in service following cocpletion of repairs to surge tank.
