Shutdown

's_J, SASES'.

LCO It is acceptable for trains to be cross tied during shutdown (continued) conditions, allowing a single offsite power circuit to supply all required trains.

The diesel generators may be considered OPERABLE with their associatad ventilation supply fans (CGH01A/B) inop trable, as long as the outside ambient te.aperature is la:,, .!.:.? nr equal to 65'F.

APPLICABILITY The AC sources required to be OPERABLE in H0 DES 5 and 6 provide assurance that:

a. Systems to provide adequate coolant inventory makeup are available for the irradiated fuel assemblies in the core:

b. Systems needed to mitigate a fuel handling accident are l available;

c. Systems necessary to mitigate the effects of events that can lead to core damage during shutdown are available; and l d. Instrumentation and control capability is available for monitoring and maintaining the unit in a cold shutdown l condition or refueling condition.

The AC power requirements for MODES 1, 2, 3, and 4 are covered in LC0 3.8.1.

ACTIONS U i

An offsite circuit would be considered inoperable if it were not l available to one required ESF train. The one train with offsite power available may be capable of supporting sufficient required

! features to allow continuation of CORE ALTERATIONS and fuel l' movement. By the allowance of the option to declare required

features inoperable, with no offsite power available,~ appropriate

! restrictions will be implemented in accordance with the affected l_ required features LC0's ACTIONS.
