ELECTRICAL = POWER SYSTEMS (SURVEILLANCE REQUIREMENTS (Continued) 14.8.1.1.2 Each diesel generato. shall be demonstrated OPERABLE:

a. At least once per 31 days cn a STACCERED TEST BASIS by:

1. ' Verifying the fuel level in the engine-mounted fuel tank,

2. Verifying the fuel level in the day fuel tank, c 3. Verifying the fuel transfer pump can be started and trensfers fuel-from the day tank to the engine mounted tank,

4. Verifying the diesel starts and accelerates to at le.ast 514 rpm in less than or equal to 10 seconds,*

5. Verifying the generator is synchronized, loaded to greater than or-equal to 1750 ku, and operates for greater than or equal to 15 minutes, and

6. Verifying the diesel generator is aligned to provide standby power to the associated emergency buses.

b. At least once per 31 days by verifying the fuel level in the plant fuel ~ storage tank. ,.

c.- -At:least once.per 92 days by verifying that a sample of diesel fuel-from the fuel storage tank, obtained-in accordance with ASTM-D270-65, is within the acceptable limits specified-in Table 1 of ASTM-D975-74

-- when checked for visect.ity, water and sediment,

d. .At least once per 18 months during' shutdown by! "
