METHOD OF PROCESSING IRRADIATED FUEL Russian patent published in 2012 - IPC G21F9/30

Abstract RU 2459299 C1

FIELD: power engineering.

SUBSTANCE: proposed method consists in thermal oxidative of irradiated fuel from uranium dioxide and comprises separating fuel elements into fragments, and oxidative treatment of said fragments by gas-air mix in two steps: first, by mix of air and carbon dioxide at 400-650°C, and, second, by steam-air mix at 350-450°C. Both steps are implemented at continuous or intermittent mechanical activation of reaction stock.

EFFECT: higher yield of tritium, reduced sublimation of cesium compounds.
