Title:
NUCLEAR REACTOR SYSTEM FOR EXTINGUISHING RADIOACTIVITY
Document Type and Number:
WIPO Patent Application WO/2017/104708
Kind Code:
A1
Abstract:
Securing a location for safely burying and disposing of high-level radioactive waste produced in a nuclear reactor in a deep stable geological layer so that living environments are not significantly affected is difficult. Provided is a nuclear reactor system and method therefor, for increasing the speed of conversion of a radionuclide to a stable nuclide to reduce radionuclide concentration using thermal neutrons produced by reducing the velocity of fast neutrons, while simultaneously subjecting fast-neutron-induced thermal energy of a primary cooling material to heat exchange with a secondary cooling material in a heat exchanger (7), and feeding the energy to a turbine system to generate power, the system having a nuclear reactor container (1) comprising a first container (11), which is an area for using fast neutrons, and a second container (12), which is an area for using thermal neutrons in the nuclear reactor, a plurality of metal fuel assemblies (22) and a liquid metal, which is the primary cooling material, being disposed in the first container, and the second cooling material capable of dual use as a neutron moderator and a MA radioactivity-extinguishing assembly or FP-extinguishing assembly (24) being loaded in the second container.
