-3.4.11 Low Temperature 0verpressure ?rotection (LTOP) System LCO 3.4.11 An LTOP System shall be OPERABLE with a maximum of one makeup pump capable of injecting into the RCS, high pressure injection (HPI) deactivated, the core flood tanks (CFTs) isolated and:

a. Pressurizer level s 155 inches and an CPERAGLE power l operated relief valve (PORV) with a lift setpoint of s 454 psig; or l
b. .The RCS depressurized and an RCS vent of 2 0.75 square inch.

APPLICABILITY: MODE 4 when. RCS temperature is s 264*F, l MODE 5, MODE 6 when the reactor vessel head is not completely detensioned.

NOTE---------------------------------

CFT isolation is only required when CFT pressure is greater than or equal to the maximum RCS pressure for the existing RCS temperature allowed by the pressure and temperature limit curves provided in the PTLR.
