SALEM UNIT 2 - PLANT SHUTDOWN GREATER THAN 72 HOURS PSE and G commenced a shutdown of Salem Unit 2 at 9:06 p.m., November 30, 1998, to repair the 21 reactor coolant pump (RCP) seal. Plant operators l have been monitoring the 21 RCP seal leakoff since November 21, 1998, when it began to increase from a normal level of 3.0 gallons per minute (GPM) to its current level of 4.5 to 5.3 GPM. After the increase, the 1 vendor was consulted and recommended verifying that the indicated seal !
' leakoff flow was accurate. PSE and G confirmed the indication through )
ultrasonic flow measurement. I Current plant procedures require a plant shutdown before seal leakoff i
. exceeded 6.0 GPM. Based on the troubleshooting results to date, PSE and I l G management decided to shutdown Salem Unit 2 to repair the RCP seal.
l They will also be performing various maintenance and surveillance
- activities.
The resident inspectors observed portions of the plant shut down and plan I to observe continuing maintenance activities on the RCP seal. The facts of this PN were verified with the Assistant Operations Manager.
Region I Public Affairs is prepared to respond to media inquires.
The States of New Jersey and Delaware have been notified.
