Subject: SHUTDOWN OF ARKANSAS NUCLEAR ONE (ANO), UNIT 1, FOR WORK ON
REACTOR COOLANT PUMP (RCP) D
Discussion:
On January 7, 2000, ANO, Unit 1, was shutdown to repair a small
lubricating oil leak on RCP D. On January 8, RCP D was secured for work
on the lube oil system. When the pump was secured, the Senior Resident
Inspector observed the pump shaft rotate in the reverse direction for
about 3 seconds until a relatively loud noise was heard, and then the
pump shaft stopped. The noise coincided with the engagement of the
anti-rotation device. Subsequently, broken parts of the anti-rotation
device were found by the licensee.
ANO Unit 1 remains shutdown pending installation of a temporary
alteration on the RCP. This alteration will be designed to prevent pump
rotation in either direction. Installation of the alteration will allow
the licensee to restart the unit operating only 3 of the 4 RCPs. The unit
is licensed and has performed the appropriate accident analyses for
operation in this configuration. In addition, training of the on-shift
crews has begun for this abnormal plant configuration.
Regional Action:
Routine resident inspector followup inspection.
