Spent Fuel Cooling

Spent Fuel Cooling


OPEN100 utilizes a unique refueling process in which the entire reactor pressure vessel and its internals are replaced at the end of the fuel cycle instead of the more complicated and lengthy conventional refueling process. Due to the small size and low relative cost of the OPEN100 reactor when compared to standard PWRs, the entire reactor can be considered disposable. At the end of the fuel cycle, the complete reactor is relocated in the containment building where decay heat is removed. In this arrangement, the reactor pressure vessel serves as the spent fuel container and cooling system. A residual heat removal system may be used for cooling of the reactor during the relocation process.



Spent Fuel Containment: Reactor vessel
Cooling Fluid: Water
Location: Containment building
Water Source: Residual heat removal system
