Diesel Fuel Oil, Lube Oil, Starting Air, and Turbocharger Air Assist 3.8.3 3.8 ELECTRICAL POWER SYSTEMS 3.8.3 Diesel Fuel Oil, Lube Oil, Starting Air, and Turbocharger Air Assist LCO 3.8.3 The stored diesel fuel oil, lube oil, starting air, and turbocharger air assist subsystems shall be within limits for each required diesel generator (DG). The fuel level for the stored diesel fuel oil shall be within the following limits:
- a.
Combined storage of 2 79,000 gal for two units in MODES 1, 2, 3, and 4; or
- b.
Combined storage of
- 1.
2 41,000 gal for one unit (if any) in MODES 1, 2, 3, and 4; and
- 2.
2 31,000 gal for each unit in MODES 5 and 6.

The performance of diesel fuel oil tank cleaning requires one fuel oil storage tank to be removed from service to be drained and cleaned.
During this time, the fuel oil storage requirement for one unit operation in MODES 1, 2, 3, and 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 2 41,000 gallons. The tank being cleaned may be inoperable for up to 10 days. For the duration of the tank cleaning, temporary onsite fuel oil storage of > 25,000 gallons will be maintained. Prior to removal of a tank from service, the offsite circuits required by LCO 3.8.1 or 3.8.2 will be verified to be OPERABLE.
