Abstract

The invention belongs to the technical field of reactor engineering and discloses a device and a method for assembling fast reactor MOX (Metal Oxide) components. The device comprises an assembling platform, a hexagonal outer sleeve fixture, a hexagonal outer sleeve, a rod cluster bracket, a component shield and a fuel rod shield, wherein the hexagonal outer sleeve fixture and the component shield are located in a first guide rail; the fuel rod shield is located on a second guide rail and is capable of horizontally moving; a slot out of which the fuel rods can be conveniently moved is formed in a side wall of the fuel rod shield. The method comprises the following steps: utilizing a fuel rod transmission line to transmit the fuel rods into the fuel rod shield; transferring the fuel rods into the component shield through the slot in the side wall of the fuel rod shield; utilizing the rod cluster bracket to bind the fuel rods into normal hexagon shape; using a pushing screw rod for horizontally pushing the hexagonal outer sleeve till the fuel rod cluster enters the hexagonal outer sleeve. The method and the device have the advantages of good shielding effect, high mounting precision and capability of enabling the operator to, manually and accurately assemble the fast reactor MOX components in a close range.

Description

technical field [0001] The invention belongs to the technical field of reactor engineering, in particular to a device and method for assembling fast reactor MOX components. Background technique [0002] A typical fast reactor MOX fuel rod consists of an upper end plug, a compression spring, a cladding tube, an upper conversion region (depleted uranium pellet), a fuel region (MOX pellet), a lower conversion region (depleted uranium pellet), a winding wire, and a lower end plug and other components, the MOX fuel pellets are sealed in the cladding tube, and both ends of the MOX fuel pellets are depleted uranium pellets with excellent gamma and neutron shielding effects. [0003] A typical fast reactor MOX assembly consists of an upper section of the assembly, a hexagonal outer sleeve, a grid plate, a lower section of the assembly, and fuel rods constrained into a hexagonal rod shape. The upper section of the assembly is provided with an operating head for grabbing the assembly...
