LIMITING CONDITIONS FOR OPERATION 3.5 CORE AND CONTAINMENT COOLING SYSTEMS C.
HPCI System
- 1.
The HPCI system shall be operable whenever there is irradiated fuel in the reactor vessel, reactor pressure is greater than 150 psig., and reactor coolant temperature is greater than 365"F, except as specified in 3.5.C.2
