Residual Heat Removal System 1.
The residual heat removal system (RIIRS) must be isolated from the reactor coolant systo.a whenever the reactor coolant system pressure exceeds 600 psig or the temperature exceeds 450

D.
Low Temperature Overpressurization Protection 1.a.
The power operated relief valves, aligned for the low pressure set point, and the RHR spring relief valves shall be operable for RCS overpressure protection when-ever the RCS is less than the minimum pressurization temperature and the RCS is not vented.
b.
If the conditions of D.I.a are not met, the RCS shall be depressurized and vented within eight hours.
EXCEPTION: One power operated relief or RHR spring relief may be inoperable for seven days.
2.
No more than one HPSI pump may be energized at RCS temperature below 220
- F.
EXCEPTION: A second HPSI pump may be energized for up to 5 minutes for the purpose of rotating operating equipment.
NOTE: Reactor Coolant Pumps may be started (or jogged) only if there is a steam bubble in the pressurizer with a maximum level of 80% or the SG/RCS temperature differential is less than 100*F.
