VIBRO-PACKING TUBE TYPE U-MO DISPERSION NUCLEAR FUEL AND PREPARATION METHOD THEREOF

摘要

A vibro-packing tube type U-Mo(Uranium-Molybdenum) dispersion nuclear fuel and a fabrication method thereof are provided to improve stability of nuclear fuel by preventing interaction between particles of the nuclear fuel and aluminum. A vibro-packing tube type U-Mo dispersion nuclear fuel includes an aluminum case(4), U-Mo alloy particles(1), and aluminum particles(2). The aluminum case is a tube type case. The U-Mo alloy particles are filled in 55 to 65% of the nuclear fuel tube case. The aluminum particles are filled among the U-Mo alloy particles in 15 to 20% of the nuclear fuel tube case and rapidly discharge heat which is generated from nuclear fuel during combustion.
