- of fuel in addition to the fuel required for the other unit.
APPLICABillTY: MODES 5 and 6.
ACTION:
With less than the above minimum required A.C. electrical power sources OPERABLE.
1 immediately suspend all operations involving CORE ALTERATIONS. positive reactivity changes, movement of irradiated fuel or crane operations with loads over the fuel storage pool. 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.
9 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.

'The performance of Technical Specification Surveillance Requirement 4.8.1.1.3.e l
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 i
requirement for one unit operation in Modes 5 or 6 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.
