Abstract
In one implementation, a passive core decay heat transport system comprising of a device in the reactor core and an assembly of heat dissipating fins is disclosed. The device comprises at least one coolant channelcontaining the fuel assembly; at least one collect jointconnecting the fuel in the assembly to shield plug; at least one liquid metal thermo-siphonfor transporting of decay heat from fuel; at least one other liquid metal thermo-siphonfor transport of heat from thermo-siphon; and at least an assembly of heat dissipating finsfor transport of heat from thermo-siphonto ultimate sink. The thermal expansion of the liquid metal by melting establishes the conductive and convective heat transfer paths and transfers the heat from the fuel assemblyto the thermo-siphon, which transports the heat to other thermo-siphonand then to the assembly of fin, which dissipates the heat by natural circulation of air to atmospheric air.
