Title:
COMPACT NUCLEAR POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/094196
Kind Code:
A1
Abstract:
[Problem] To build a secure and high-efficiency power generation system while achieving a further reduction in the size of the entire system. [Solution] A compact nuclear power generation system is provided with a reactor (3) comprising a core (2) which uses metal fuel containing either or both of uranium-235/238 and plutonium-239, a reactor vessel (1) which houses the core (2), metal sodium which is filled into the reactor vessel (1) and heated by the core (2), and a neutron reflector (9) which maintains the effective multiplication factor of neutrons emitted from the core (2) at approximately one or more to bring the core into a critical state. A main heat exchanger (15) is installed outside the reactor (3). The metal sodium heated by the reactor (3) is supplied to the main heat exchanger (15), and supercritical carbon dioxide that is subjected to heat exchange with the heated metal sodium circulates therethrough. The supercritical carbon dioxide heated by the main heat exchanger (15) drives a turbine (20), and a power generator (21) is operated by the drive of the turbine (20).
