Reactor Coolant Pumps

The reactor coolant pumps are single stage, centrifugal pumps that circulate the reactor coolant between the reactor vessel and the superheater and steam generator. Pump sizing is sufficient so that if one pump is lost from service, the remaining pump can increase its load capacity to maintain operation of the reactor. The pumps are vertical canned pumps of an extremely robust design and do not include mechanical seals and their associated leakage concerns.
