3 2F32-Reactor scram due to generator lockout. During the opening of the 135 breaker, the
'B' phase experienced an internal fault. The CT on the 345 breaker failed resulting additional breaker trips that led to the turbine trip. The breakers were repaired/replaced.
SUMMARY
Unit 2 began the month of June 2004 at 100.0% of rated thermal power (RTP).
On June 22" at 13:12 hours, the main turbine automatically tripped due to generator lockout which resulted in an automatic reactor scram, at 99.9% RTP.
On June 23 'd at 20:04 hours, reactor criticality was achieved.
On Junee24' at 11:16 hours, the main generator was synchronized to the grid at 18.7% RTP. At 14:23 hours, the main generator was tripped at 22.1 % RTP for voltage regulator and overspeed testing. At 15:11 hours the main generator was resynchronized to the grid at 19.9% power.
On June 2 7 In at 20:46 hours, reactor power was restored to 100.0% RTP.
Unit 2 ended the month of June 2004 at 99.9% RTP.
