An OPERABLE RHR shutdown cooling subsystem consists of an RHR pump and the associated heat exchanger, an RHRSW pump providing cooling to the heat exchanger with sufficient flow to maintain reactor coolant temperature in the desired range, valves, piping, instruments, and controls to ensure an OPERABLE flow path. The two required RHR shutdown cooling subsystems have a common suction source and are allowed to have a common heat exchanger and common discharge piping.

2 subsystems meet by one of the following combinations:
1 pump in each loop, 2 Hx’s, and 1 RHRSW pumps per Hx.
or
2 pumps in one loop, one HX, and 2 RHRSW pumps for one Hx
