Residual Heat Removal

Residual Heat Removal


The Residual Heat Removal System (RHRS) is employed as cooling for the reactor core during outages to remove its decay heat. The RHR pumps replace the function of the reactor coolant pumps after the RCS pressure is reduced to 425 psig and temperatures in the core drop below 350 deg F. The RHRS also provides cooling to the spent fuel storage and operates in a recirculation mode during normal plant operation in that service.



Design Pressure: 150 psig
Design Temperature: 325 deg F
Design Flow Rate: 750 gpm
Material: SA376-TP316L
Size: 6 inch
