Abstract
A liquid metal cooled fast breeder nuclear reactor of the pool kind has an intermediate heat exchange module comprising a tube-in-shell heat exchanger and an electromagnetic flow coupler in the base region of the module. Primary coolant is flowed through the heat exchanger being driven by electromagnetic interaction with secondary liquid metal coolant flow effected by a mechanical pump.
Claims3
A liquid metal cooled nuclear reactor comprising:
- a primary vessel;
- a fuel assembly submerged in a pool of primary liquid metal coolant within the primary vessel;
- a concrete vault housing said primary vessel;
- at least one heat exchange module carried by a roof of the vault and immersed in the pool of coolant, and
- a pump for circulating primary coolant from the pool through the fuel assembly to the heat exchange module, the heat exchange module comprising a tube-in-shell heat exchanger and an electromagnetic flow coupler disposed in the base region of the module for driving primary coolant through the heat exchanger, the electromagnetic flow coupler being associated with a secondary coolant circuit from which the driving effort for the primary coolant is derived.
