METHOD OF OXIDIZING PROCESSING (VOLOXIDATION) OF IRRADIATED NUCLEAR FUEL Russian patent published in 2017 - IPC G21C19/42

Abstract RU 2619583 C1

FIELD: chemistry.

SUBSTANCE: essence of the invention consists in the simultaneous action on the fuel composition of theoxidation-active components CO₂-containing gas-phase system, while limiting the concentration of nitrogen dioxide, oxygen, nitric acid in it.

EFFECT: invention makes it possible to reduce the separation of cesium from the effluent gas stream to a level of less than 0,1 percent when more than 99,8 percent of tritium is removed during the process of the fragmentation of SNF.
