Condition C is the default Condition should Required Action A.1 or B.1 not be met within the associated Completion Time.

Required Action C.1 ensures that Required Actions for affected diesel generator inoperabilities are initiated.

Depending on MODE, the Actions specified in LCO 3.8.1, "AC Sources-Operating," or LCO 3.8.2, are required to be entered immediately.

SURVEILLANCE SR 3.3.8.1 REQUIREMENTS A CHANNEL FUNCTIONAL TEST is performed on each required EDG LOPS channel to ensure the entire channel will perform the intended function. This test ensures functionality of each 1 channel to output relays, i The Frequency of 31 days is considered reasonable based on the reliability of the components and on operating experience.

A temperary extensicn cf the frequency has been made-to indicate "31-days or 50 days" as the frequency. This temporary conditica applies tc a one-time performance-of-the surveillance en each diesel generator-end will not be effective after November 23, 1997. The need for this te,,prary extensica of the frequency becs.c evident durir,g replac acnt of the radiator cn the EOCs.
