Slag-free process for plasma reduction of uranium from oxide raw material

摘要

The results of large-scale experiments on plasma carbotbermal reduction of uranium from oxide raw material are presented. The results of experiments are analysed on the basis of thermodynamic research of system U-C-O, in particular influences of solid solutions and role of the plasma heat-carrier on an output of products and on technological parameters of the process. It is shown that refining of uranium up to a level of the requirements of the certificate is achieved with use of electron-plasma heating. The economic and ecological aspects of production of natural and regenerated uranium from oxide raw material are considered at which there is reducing nuclear fuel cycle and also scientific and technical concepts of organization of new production.
