METHOD OF DISSOLVING MOX FUEL Russian patent published in 2012 - IPC C01G43/00 C01G56/00 G21C19/42

Abstract RU 2451639 C1

FIELD: chemistry.

SUBSTANCE: invention relates to methods of dissolving fuel which is a mixture of uranium and plutonium oxides. The method involves dissolving MOX fuel in a nitric acid solution which also contains fluoride and gadolinium ions with the following concentrations: nitric acid (6-9) mol/l, sodium fluoride (0.05-0.08) mol/l and gadolinium nitrate in terms of gadolinium (1.3-1.5) g/l.

EFFECT: invention enables complete dissolution of mixed uranium-plutonium fuel without formation of residues and nuclear safety of the dissolution process.
