Subject: MANUAL REACTOR TRIP AND SUBSEQUENT RESTART
Discussion:
On August 15, 2001, at 4:49 a.m., Unit 3 was manually tripped from 15
percent power due to a reduction in condenser vacuum. Two intermediate
range nuclear instrumentation detectors and one individual rod position
indicator (all rods were inserted fully) did not function as expected
following the reactor trip. The unit was placed in Hot Standby for repair
activities.
The licensee determined that the reduction in condenser vacuum was the
result of leakage through holes in two tubes in the main condenser. The
holes were caused by loose flashing material inside the condenser (sheet
metal used to protect expansion joints and bellows) impacting the tubes.
The affected tubes were identified and repaired. The licensee replaced
both intermediate range detectors and is evaluating the cause of the
failures. The rod position indicator issue was attributed to a control
panel indicator problem and was corrected.
Unit 3 returned to power operation on August 20, 2001.
