ELECTRICAL POWER SYSTEMS SURVEILLANCE REQUIREMENTS (Continued)

C) Verifying that all nonessential automatic diesel generator trips (i.e., o-:her t.:ian engine overspeed-, lube oil pressure low, 4 KV bus differential and generator differential), are automatically bypassed upon loss of voltage on the vital bus concurrent with a safety injection actuation signal.

7. Verifying the diesel generator operates for at least 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />s*.

During the first 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> of this test, the diesel generator shall be loaded to 2760-2860 kw.** During the remaining 22 hours2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br /> of this test, the diesel generator shall be loaded to 2500-2600 kw*** The steady state voltage and frequency shall be maintained at ~ 3950 and

~ 4580 volts and 60 +/- 1.2 Hz during this test. Within 5 minutes after completing this 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> test, perform Surveillance Requirement 4.8.1.1.2.d.6.b.***

8. Verifying that the auto-connected loads to each diesel generator do not exceed the two hour rating of 2860 kw.

9. Verifying that with the diesel generator operating in a test mode (connected to its bus), a simulated safety injection signal overrides the teat mode by (1) returning the diesel generator to standby operation and ( 2) automatically energizing the emer.gency loads with offsite power.

e. At least once per ten years or after any modifications which could affect diesel generator interdependence by starting all diesel generators simultaneously*, during shutdown, and verifying that all diesel generators accelerate to at least 900 rpm in less than or equal to 10 seconds.

4.8.1.1.3 The diesel fuel oil storage and transfer system shall be demonstrated OPERABLE:

a. At least once per 31 days by:

1. Verifying the level in each of the above required i8, 000 gallon fuel storage tanks.

2. Verifying that both fuel transfer pumps cari be started and transfer fuel from the 29 1 999 tall~orage tanks to the day tanks. ~

b. At least once per 92 days by verifying that a sample of diesel fuel from each of the above required 29 1 999 CJAllQR fuel storage tanks is within the acceptable limits specified in Table 1 of ASTM 0975-77 when checked for viscosity, water and sediment.
