- The performance of modifications to the diesel fuel oil storage and transfer j
system requires one fuel oil storage tank at a time to be drained and replaced i
with a'new storage tank. During this period, the diesel generator fuel oil storage requirement for two unit operation in Modes 1 - 4, or for one unit operation in Modes 1 - 4 and one unit in Mode 5 or 6 is 35,000 gallons. A total of up to 120 days may be required to complete the replacement of both tanks.
For the duration of the tank replacement, temporary onsite storage of 30,000 gallons will be maintained. Prior to removal of a tank from service, the offsite circuits required by Technical Specification 3.8.1.la. will be
