Abstract
A device for pulverizing incombustible large solid radioactive wastes arising from atomic power plants or the like. The device comprises a furnace body provided with a vacant space for melting radioactive wastes, a gripper mounted on the furnace body to support the radioactive waste, plasma torches mounted on the furnace body to irradiate a plasma arc toward the lower end of the wastes, and a water vessel disposed below the vacant space.
Claims8
A pulverising device comprising:
- (i) a hollow furnace body defining a space for the melting of a portion of radioactive waste,
- (ii) a gripper mounted on said furnace body and adapted to support a portion of radioactive waste in said space in said furnace body,
- (iii) plasma torch means mounted on said furnace body and directed to irradiate a plasma arc toward a lower end of said portion of radio-active waste supported by said gripper, and
- (iv) a water vessel disposed below said space for storage of water,
- whereby said portion of radio-active waste is heated so as to be melted within said space by said plasma arc, and the molten waste falls as a succession of drops into said water and becomes pulverised.
