摘要
The present invention relates to a method for producing a dry reprocessed fuel sintered body by a one-time oxidation / reduction process and the addition of a sintering accelerator, and an object thereof is to provide oxidation and reduction in an oxidation / reduction process when manufacturing a dry reprocessed fuel sintered body using spent fuel. The sintered compact is manufactured to have a small powder size and a large specific surface area to improve powder sinterability. It is to provide a method for producing a dry reprocessed fuel sintered body showing.;According to an aspect of the present invention, there is provided a method of manufacturing a nuclear fuel sintered body for use in a heavy water reactor type nuclear power plant by reprocessing spent fuel discharged after burning in a light water reactor type nuclear power plant using a single oxidation / reduction step; A fine grinding step for miniaturization to improve the sinterability of the powder; In order to promote the sinterability of the powder prior to molding, characterized in that consisting of a sintering promoter Nb 2 O 5 including the step of producing a sintering process.;Dry Reprocessing Nuclear Fuel, Oxidation, Reduction, Sintering Promoters, Additives
