AC Sources-Operating 3.8.1 SURVEILLANCE REQUIREMENTS (continued)

SURVEILLANCE SR 3.8 1.9 SR 3.8.1.10 NOTE "1.

This Surveillance shall not be performed in MODE 1 or 2. (Not applicable to DG 1C)

However, credit may be taken for unplanned events that satisfy this SR.

2.

If performed with DG synchronized with offsite power, it shall be performed at a power factor

< 0.9 Verify each DG rejects a load greater than or equal to its associated single largest post accident load and following load rejection, the engine speed is maintained less than nominal plus 75% of the difference between nominal speed and the overspeed trip setpoint or 15% above nominal, whichever is lower.

NOTE This Surveillance shall not be performed in MODE 1 or 2. (Not applicable to DG 1C) However, credit may be taken for unplanned events that satisfy this SR.

Verify each DG operating at a power factor< 0.9 does not trip and voltage is maintained < 4784 V for DG 1A and DG 1 B and < 5400 V for DG IC during and following a load rejection of a load > 3030 kW and
