ELECTRICAL POWER SYSTEMS SURVEILLANCE REQUIREMENTS (Continued) during this test. Within 5 minutes after completing this l
24-hour test, perform Specification 4.8.1.1.2g.6)b),*
8)
Verifying that the auto-connected loads to each diesel generator do not exceed 5750 kW;**
l 9)
Verifying the diesel generator's capability to:**
l a)
Synchronize with the offsite power source while the
. generator is loaded with its emergency loads upon a simulated restoration of offsite power, b)
Transfer its loads to the offsite power sourr.e, and c)
Se restored to its standby status.
- 10) Verifying that with the diesel generator operating in a test mode, connected to its bus, a simulated Safety Injection signal cverrides the test mode by: (1) returning the diesel generator to standby operation, and (2) automatically energizing the emergency loads with offsite power;**
l
- 11) Verifying that the fuel transfer valve transfers fuel from each fuel storage tank to the day tank of each diesel via the in-stalled cross-connection lines;
- 12) Verifying that the automatic load sequence timer is OPERABLE with the interval between each load block within the tolerances given in Table 4.8-2;
- 13) Verifying that the voltage and diesel speed tolerances for the accelerated sequencer permissives are 92.5 i 1% and 98 + 1%,
respectively, with a minimum time delay of 2
- 0.2 s; and
- 14) Verifying that the following diesel generator lockout features prevent diesel generator starting only when required:
a)
Turning gear engaged, or b)
Maintenance mode.
"If Specification 4.8.1.1.2g.6)b) is not satisfactorily completed, it is not necessary to repeat the preceding 24-hour test.
Instead, the diesel generator may be operated at greater than or equal to 5600 kW but less than or equal to 5750 kW for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> or until operating temperature has stabilized.
- This surveillance need.not be performed until prior to entering HOT SHUTDOWN following the Unit 1 first refueling.
