Metal fuel based thorium epithermal neutron reactor core and nuclear reactor having the same

摘要

The core of a metal fuel-based thorium thermal neutron according to an embodiment of the present invention includes: a nuclear fuel assembly including a plurality of nuclear fuel bodies for a nuclear fission chain reaction to occur; A coolant disposed between the nuclear fuel assemblies to absorb energy released by the nuclear fission chain reaction; And a reflector disposed to surround the fuel assembly and reducing external leakage of neutrons generated from the fuel assembly, wherein the fuel body includes a thorium and uranium metal, a zirconium alloy, and a neutron energy region transition additive. It is formed of, the thorium is Th-232, the uranium may be provided as U-233 to ensure the non-proliferation resistance of the thorium cycle.
