While shutting down for the scheduled outage, with Unit 1 at 20% power, the East MFP shaf t driven tube oil pump suction piping was found leaking, resulting.in reduced tube oil p ressu re.

The leak was due to a crack at the threaded connection of-the suction piping to the shaft driven lube oil pump.

The crack either pre-existed or was initiated during installation, and propagated over a period of time due to normal-pump vibration. As corrective action, new suction piping connections were fabricated and installed on the East and West MFP shaft driven tube oil pump.. The East MFP was returned to service and monitoring of oil leaks continued.
