lll 3/4.5 EMERGENCY CORE COOLING SYSTEMS (ECCS)
SAFETY INJECTION TANKS LIMITII;G CONDITION FOR OPERATION 3.5.1 Each reactor coolant system safety injection tank shall be OPERABLE with:
a.
The isolation valve open, b.
A cnntained borated water volume of between 1113 and 1179 cubic feet of borated water (equivalent to tank levels of between 187 anc 199 inches, respectively),
c.
A boron concentration of cetween 1720 and 2200 ppm, and d.
A nitrogen cover-pressure of ce: ween 2C; E 250 psig.
APPLICABILITY: MODES 1, 2 and 3.*
ACTION:
a.
With one safety injection tank inoperaDie, except as a rest.t of a closed isolation valve, restore the inoperable tank tc OPERABLE status within one hour or be in HOT SHUTD0'.C. withi-
