I ELECTRICAL POWER SYSTEHS A.C. SOURCES - SHUTDOWN LIHITIHG COHDITIOH FOR OPERATION 3.8.1.2 As a minimum, the following A.C. electrical power sources shall be OPERABLE:

a~ One circuit between the offsite transmission network and the onsite Class 1E distribution system, and

b. Diesel generator 1 or 2 (DG-1 or DG-2), and diesel generator 3 (DG-3) when the HPCS system is required to be OPERABLE, with each diesel generator having:

1. Day fuel tanks containing a minimum of 1400 ga f fuel.

2.

I A fuel storage system containing a minimum fuel for DG-1 and DG"2, and 33,000 gallons of

~K allons of or DG-3.

3. A fuel transfer pump.

APPLICABILITY: OPERATIONAL CONDITIONS 4, 5, and ".

ACTION:

a. With less than the offsite circuits and/or OG-1 or OG-2 of"the above required A.C. electrical power sources OPERABLE, suspend CORE ALTERATIONS, handling of irradiated fuel in the secondary containment, operations with a potential for draining the reacto~ vessel'nd crane operations over the spent fuel storage pool when fuel assemblies are stored therein. In addition, in OPERATIONAL CONDITIOH 5, with the water level less than 22 feet above the reactor pressure vessel flange, immediately initiate corrective action to restore the required power sources to OPERABLE status as soon as practical.

b. With DG-3 of the above required A. C. electrical power sources inoperable, restore the inoperable diesel generator 1C to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or declare the HPCS system inoperable and take the ACTIOH required by Specification 3.5.2 and 3.5.3 C. The provisions of Specification 3. 0.3 are not applicable.

SUR'/EILLANCE REQUIREMENTS 4.8.1.2 At least the above required A.C. electrical power sources shall be demonstrated OPERABLE per Surveillance Requirements 4.8.1.1.1, 4.8.1.1.2, and 4.8.1.1.3, except for the requirement of 4.8.1.1.2.a.5.
