Abstract
A compact nuclear power generation system includes a reactor () comprising a core () which uses metal fuel containing either or both of uranium-235/238 and plutonium-239. A reactor vessel () houses the core (). Metal sodium primary coolant () is heated by the core (). A neutron reflector () maintains the effective multiplication factor of neutrons emitted from the core () at approximately one or more to bring the core into a critical state. The neutron reflector is movable from a lower part towards an upper part of the core. The heated metal sodium is supplied to a main heat exchanger () which is located outside the reactor. A secondary coolant of supercritical carbon dioxide, which circulates through the main heat exchanger, is in heat exchange with the heated metal sodium. The heated secondary coolant drives a turbine (). A power generator () can be operated by the driven turbine.
