Reactor Internal Pump
BWR utilize a forced circulation system for the reactor coolant that intensifies steam generation at the reactor core.
ABWR further enhances plant reliability, safety and operating economy by use of reactor internal pumps (RIP). The reactor coolant is circulated by 10 RIP installed in the RPV.
Each is driven by a wet stator motor mounted in a motor casing. The speed of the pump controls the coolant flow rate, which enables control of the reactor output.
