FIELD: chemistry.
SUBSTANCE: invention consists in coarsening the sediment grain by integrating an organic component in its composition in the precipitation of the peroxide compounds of uranium and plutonium in the presence of amino acids, in using thermal decomposition products of amino acids in the reduction process, with their complete removal into the gas phase due to thermal treatment in a gas stream containing vapours of formic acid.
EFFECT: invention allows to simplify and improve the safety of the technological process.
