4.8.1.1.1 Eat.h of the above required independent circuits between the off5ite transmission network and the onsite Class 1E distribution system shall be:
- a. Determined OPERABLE at least once per 7 days by verifying correct breaker alignments and indicated power availability, and
- b. Demonstrated OPERABLE at least once per 18 months during shutdown by manually transferring unit power supply from the normal circuit to the alternate circuit.
- 4. 8.1.1. 2 Each of the above required diesel generators shall be demonstrated OPERABLE:
- a. In accordance with the frequency specified in Table 4.P.1.1.2-1 on a STAGGERED TEST BASIS by:
- 1. Verifying the fuel level in the day tank.
- 2. Verifying the fuel level in the fuel storage tank,
- 3. Verifying the fuel transfer pump starts and transfets fuel from the storage system to the day tank.
4.* '/erifying the diesel starts from standby condition and acceler-ates to at least 441 rpm for diesel generators 11 and 12 and 882 rpm for diesel generator 13 in less than or equal to 10 sec-onds. The generator voltage and frequency shall be 4160 i !
^
416 volts and 6011.2 Hz within 10 seconds after the start signal. The diesel generator shall be started for this test by using one of tht "o11owing signals:
a) Manual, b) Simulated loss of offsite power by itself, c) Simulated loss of offsite power in conjunction with an ESF 1 actuation test signal. !
d) An ESF actuation test signal by itself.
- All diesel generator starts for the purpose ( 'his Surveillance Requirement may be preceded by an engine prelube period. . diesel generator start (10 sec) from standby conditicns shall be performed at least once per 184 days in these surveillance tests. All other engine starts for the pur- '
pose of this surveillance testing may be preceded by warmup procedures as rec-ommended by the manufacturer so that the mechanical stress and wear on the diesel engine are minimized.
