5~0 PRECAUTIONS:
5.1 To protect NIS detectors a Reactor Compartment fan cooler muat be in service when temperature in RCS is above 135 5.2 A rod control shroud fan must be in operation when RCS temperature is greater than 135 F.
5.3 The Safety Injection signal from secondary side (Low steam Pressure, < 514 psig) must be defeated, during hydro, whenever RCS pressure is in excess of 1992 psig (automatic unblock of S.I.).
5.4 The over pressure protection system shall be in operation whenever RHR is in service.
5.5 The Residual Heat Removal System must be isolated from the Reactor Coolant System before increasing system pressure above 450 psig.
5 ' Both pressurizer PORVs must be operable with a lift setting of < 410 psig (435 psig. T.S.) and aligned per 0-7 whenever the temperature of one or more of the RCS cold legs is < 350 F (330 F T.S.), or the residual heat removal system is in operation, except one PORV may be inoperable for seven days. If these conditions cannot be met, the Primary System must be depressurized and vented through a > 1.1 square inch vent(s) within next 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />.
