LIMITING CONDITION FOR OPERATION
- 3. 8.1.1 As a minimum, the following A.C.' electrical power sources shall be j
OPERABLE:
Two physically independent circuits between the offsite transmission a.
network and the Onsite Essential Auxiliary Power System, and b.
Two separate and independent diesel generators, each with:
t 1)
A separate day tank containing a minimum volume of 120 gallons of fuel, 2)
A separate Fuel Storage System containing a minimum volume of
'28,000 gallons of fuel, and 3)
A separate fuel transfer pump.
APPLICABILITY: MODES 1, 2, 3, and 4.
