, LIMITING CONDITION FOR OPERATION 3.8.1.1 As a minimum, the following A.C. electrical power sources shall be OPERABLE:
a.
Two independent circuits (one with delayed access) between the offsite transmission network and the Onsite Class IE Distribution System, and b.
Three separate and independent diesel generators,* each with:
1.
A separate engine-mounted fuel tank containing a minimum volume of 200 gallons of fuel, and 2.
Two supply trains of the Diesel Fuel Oil Storage and Transfer System containing a minimum combined storage of 33,000 gallons of fuel for one unit operation ** and 65,000 gallons of fuel for two unit operation.
APPLICABILITY:
M3 DES 1, 2, 3, and 4.

With a diesel ge wrator of the above required A.C. electrical power sources inoperable, demonstrate the OPERABILITY of the A.C. offsite sources by performing Specification 4.8.1.1.la within I hcur and at least once per 8 hot.rs thereafter; and if the diesel generator became inoperable due to any cause other than preventive maintenance or
- For a five diesel generator configuration, OPERABILITY of the third (comon) diesel generator shall include the capability of functioning as a power source for the required unit upon automatic demand from that unit.
- The perform nce of Technical Specification Surveillance Requirement 4.8.1.1.3.e requires one fuel oil storage tank to be removed from service to be drained and cleaned.
During this surveillance, the diesel generator fuel oil storage requirement for cne unit operation in Modes I through 4 and one unit operation in Mode 6 with at least 23 feet of water above the reactor vessel flange or with the reactor vessel defueled is 35,000 gallons. The tank being cleaned may be inoperable for up to 10 days.
For the duration of tank cleaning, temporary onsite fuel oil storage of 24,000 gallons will be maintained.
Prior to removal of a tank from service, the offsite circuits required by Technical Specification 3.8.1.1.a will be verified to be OPERABLE.

With one offsite circuit and one diesel generator of the above c.
required A.C. electrical power sources inoperable, demonstrate the OPERABILITY of the remaining A.C. sources by performing Specifica-tion 4.8.1.1.la within I hour and at least once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> there-l after; and if the diesel generator became inoperable due to any cause other than preventive maintenance or testing, demonstrate the OPER-ABILITY of the remaining OPERABLE diesel generators by performing Specification 4.8.1.1.2a.2) within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />; restore at least one of the inoperable sources to OPERABLE status within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 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 />. Restore the other A.C. power source (offsite circuit or diesel generator) to OPERABLE status in accordance with l
ACTION a. or b., as appropriate with the time requirement of that ACTION statement based on the time of initial loss of the remaining inoperable A.C. power source. A successful test of diesel OPERA-BILITY per Specification 4.8.1.1.2a.2) performed under this ACTION statement for OPERABLE diesels or a restored to OPERABLE diesel satisfies the diesel generator test requirement of ACTION a. or b.
