COMMENCEMENT OF TECH SPEC REQUIRED SHUTDOWN
"At 16:47 (EST) Unit 1 experienced a loss of Channel 12 Reactor Protection System (RPS). Power to RPS Bus 12 was shifted to its backup power supply. This was coincident with Emergency Diesel Generator 102 (EDG) being inoperable. This condition requires commencement of a Plant Shutdown within 1 hour and be in a Cold Shutdown Condition in ten hours (LCO for TS 3.6.3 - Emergency Power Sources). At 1746 a shutdown was commenced in accordance with N1-OP-43C. At 1900 a successful post maintenance test was completed on EDG 102 and EDG 102 was declared operable. Plant Shutdown actions have been terminated and the 1 and 10 hour shutdown LCO exited. The plant is at 98.6 percent power and remains in a 7 day LCO in accordance with TS 3.6.3 (Emergency Power Sources).
"Investigation is underway into the cause of the loss of RPS Bus 12."
Also, the loss of one half of the 'Energize to Function' portion of the Automatic Depressurization System.
The NRC Resident will be informed of this event.
