ALKALINE DISSOLUTION OF FUEL RODS OF RESEARCH REACTORS WITH A DISPERSION FUEL COMPOSITION

The results of studies are presented to determine the possibility of removing the aluminum matrix of dispersion fuel rods by alkaline dissolution, followed by the transfer of insoluble compounds of nuclear materials and fission products for processing according to the scheme currently adopted at FSUE "PO "Mayak". The distribution of uranium, aluminum, and silicon along the technological streams formed at the stage of alkaline dissolution is estimated, and the advantages and disadvantages of the proposed operation are discussed.
