EQUIPMENT FOR REPROCESSING OF CERAMIC NUCLEAR FUEL Russian patent published in 1995 - IPC

FIELD: nuclear technology. SUBSTANCE: upper part of vertical apparatus for reprocessing of ceramic nuclear fuel has branch pipes for loading of fuel and removal of oxidized fuel and lower part of apparatus includes gas distribution device for supply of gas mixture. Part of apparatus body above gas distribution device and branch pipe for loading of fuel are manufactured in the form of truncated cones widening downwards. Maximum productivity of equipment is achieved at apparatus angle of 2-8 deg at cone vertex, at angle exceeding 11 dwg no increment of productivity is obtained. EFFECT: increased productivity of equipment with keeping of geometrical dimensions specified by conditions of nuclear safety, enhanced efficiency thanks to automatic maintenance of constant volume of fuel in equipment. 2 cl, 1 dwg
