3/4.8 ELECTRICAL POWER SYSTEMS
- *3/4.8.1 A.C.
SOURCES OPERATING LIMITING CONDITION FOR OPERATION 3.8.1.1 As a minimum, the following A.C electrical power sources shall be OPERABLE:
- a.
Two physically independent circuits between the offsite transmission network and the onsite Class 1E distribution system.
and
- b.
Two separate and independent diesel generators. each with:
- 1.
A separate day tank containing a minimum of 1457 gallons of
- fuel,
- 2.
A separate main fuel oil storage tank containing a minimum of 100.000 gallons of fuel. and
- 3.
A separate fuel oil transfer pump.
- c.
Automatic Load Sequencers for Train A and Train B.
APPLICABILITY:
MODES 1. 2. 3 and 4.
ACTION:
- a.
With one offsite circuit of 3.8.1.1.a inoperable:
- 1.
Perform Surveillance Requirement 4.8.1.1.1.a within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> thereafter: and
- 2.
Restore the offsite circuit 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 be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />; and
- 3.
Verify required feature(s) powered from the OPERABLE offsite A.C.
source are OPERABLE.
If required feature(s) powered from the OPERABLE offsite circuit are discovered to be inoperable at any time while in this condition, restore the required feature(s) to OPERABLE status within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> from discovery of inoperable required feature(s) or declare the redundant required feature(s) powered from the inoperable A.C. source as inoperable.

ELECTRICAL POWER SYSTEMS "A.C. SOURCES SHUTDOWN LIMITING CONDITION FOR OPERATION 3.8.1.2 As a minimum, the following A.C electrical ro,.er sources shall be OPERABLE a
One circuit between the offsite transmission network and the onsite Class 1E dlstrIDutlon system, and
- b.
One diesel generator with:
- 1.
Day tank containing a minimum volume of 1457 gallons of
- fuel,
- 2.
A separate main fuel oil storage tank containing a minimum volume of 100.000 gallons of fuel. and
- 3.
A fuel oil transfer pump.
APPLICABILITY:
MODES 5 and 6.
ACTION:
With less than the above minimum required A.C. electrical power sources OPERABLE.
immediately suspend all operations involving CORE ALTERATIONS.
positive reactivity changes, movement of irradiated fuel, or crane operation with loads over irradiated fuel and within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. depressurize and vent the Reactor Coolant System through a vent of greater than or equal to 2.9 square inches.
In addition, when in MODE 5 with the reactor coolant loops not filled, or in MODE 6 with the water level less than 23 feet above the reactor vessel flange. immediately initiate corrective action to restore the required sources to OPERABLE status as soon as possible.
SURVEILLANCE REQUIREMENTS 4.8.1.2 The above required A.C. electrical power sources shall be demonstrated OPERABLE by the performance of each of the requirements of Specifications 4.8.1.1.1 and 4.8.1.1.2.
