NUCLEAR REACTOR FUEL
Document Type and Number:
WIPO Patent Application WO/2022/225611
Kind Code:
A3
Abstract:
A nuclear fuel system (210), nuclear fuel particle (100), and method for operating a nuclear fuel system are disclosed. A nuclear fuel system includes a matrix (130) material and a plurality of fuel particles (100) disposed in the matrix material, each fuel particle comprising a fuel kernel (110) and a fuel coating (120) that covers a surface of the fuel kernel. The fuel kernel comprises a fissile material including one or more of uranium-233, uranium-235, or plutonium-239. The fuel coating is functionally graded in density. A density of the fuel coating increases along an outward radial direction referenced to the center of the fuel kernel. The fuel coating comprises a neutron moderating material. A volume fraction of fuel particles is thirty-five percent or more of a volume of a nuclear fuel compact.
