53.15 H
3 06/01/2005 - CAP 02005-2337. Reactor scrammed due to apparent load reject.
First Energy closed in bad lightning arrestors inside the Manitou Substation.
This caused a voltage transient on the 230KV system which lead to a generator lockout (from a loss of two of three 230KV lines exiting the substation) and subsequent turbine trip and reactor scram.
SUMMARY
- The planned losses for June, which include operating the plant with margin to the license limit and condenser losses, totaled 6,628.9 MWhrs. A forced outage (1 F08) caused by a grid disturbance occurred June 1 at 21:09 Hours and ended June 4 at 02:18 hours. The 53.15-hour forced outage was beyond Plant Management's control, therefore, the lost generation associated with the outage (38,655 MWhrs) is not included in the Forced Loss Rate calculation 1
