~.7 ELECTRICAL Applicability Applies tG the availability of electrical power for the operation of plant components.

Objective To define those conditions of electrical power availability necessary to provide for safe reactor operation and the continuing availability of engineered safety features.

3.7.1 Specifications The primary coolant system shall not be heated or maintained at temperatures above 325°F if the following electrical systems are not operable:

a. Station power transformer 1-2 (2400 V).

b. Start-up transformer 1-2 (2400 V).

c. 2400 V engineered safeguards buses lC and 10.

d. 480 V distribution buses 11 and 12.

e. MCC No 1, 2, 7 and 8.

f. 125 V d-c buses No 1 and 2.

g. Four preferred a-c buses.

h. Two station batteries and the d-c systems including at least one battery charger on each bus.

i. Both diesel generators, with a minimum of 2500 gallons of fuel in each day tank a minimum of 16,000 gallons of fuel in the underground storage tank.

j. Switchyard battery and the d-c system with one battery charger.

k. 240 V a-c power panels No 1 and 2, and their associated ACB breaker distribution systems.

1. 2400 V bus lE.

3.7.2 The requirements of Specification 3.7.1 may be modified to the extent that one of the following conditions will be allowed. If any of the provisions of those exceptions are violated, the reactor shall be placed in a hot shutdown condition within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
