ELECTRICAL POWER SYSTEMS SURVEILLANCE RE0VIREMENTS (Continued) .

b) A kinematic viscosity at 40*C of greater than or equal to 1.9 centistokes, but less than or equal to 4.1 centistokes (alternatively, Saybolt viscosity, SUS at 100'F of greater than or equal to 32.6, but not less than or equal to 40.1), if gravity was not determined by comparison with the supplier's certification; c) A flash point equal to or greater than 125'F; and d) A clear and bright appearance with proper color when tested in accordance with ASTM-D4176-E2.

2) By verifying within 30 days of obtaining the sample that the other properties specified in Table 1 of ASTM-D975-81 are met when tested in accordance with ASTM-D975-81 except that the analysis for sulfur may be performed in accordance with ASTM-D1552-79, ASTM-02622-82 or ASTH-D4294-83,

f. At least once every 31 days by obtaining a sample of fuel oil in accordance with ASTM-D2276-78, and verifying that total particulate contamination is less than 10 mg/ liter when checked in accordance with ASTM-D2276 78, Method A;

g. At least once per 18 months, during shutdown, by:

1) Subjecting the diesel to an inspection in accordance with procedures prepared in conjunction with its manufacturer's recommendations for tnis class of standby service;*

2) Verifying the generator capability to reject a load of greater than or equal to 595 M! while maintaining voltage at 4160 420 volts and frequency at 60 3 Hz;

3) Verifying the generator capability to reject a load of 4986 kW without tripping. The generator voltage shall not exceed 4784 volts during and following the load rejection;

4) Simulating a loss-of-offsite power by itself, and:

a) Verifying deenergiz . ion of the emergency busses and load shedding from the emergency busses, and b) Verifying the diesel starts on the auto-start signal, energizes the emergency busses with permanently connected loads within 11 seconds, energizes the auto-connected shutdown loads through the load sequencer and operates for greater than-or equal to 5 minutes while its generator is loaded with the shutdown loads. After energization, the steady-state voltage and frequency of the emergency busse::

shall be maintained at 4160 420 volts and 60 0.8 Hz

during this test.

l *Except that the Surveillance Requirement inspection due no later than l December 25, 1992 may be deferred until the next refueling outage, but no

, later than September 30, 1993 or whichever is earlier, i
