摘要：

The efficiency of voloxidation of mixed nitride uranium-plutonium spent nuclear fuel (MNUP SNF) for the separation of the fuel composition from the fuel rod cladding and removal of H-3 and C-14 was estimated. It was shown that the completeness of SNF separation from fuel rod cladding under optimal conditions is at the level of 98-99%. The residual content of tritium in the voloxidized fuel does not exceed 0.2% of its content in the original SNF sample; radiocarbon is removed by 98%.
