THE MELT REFINING OF IRRADIATED URANIUM: APPLICATION TO EBR-II FAST REACTOR FUEL. VIII. THE BEHAVIOR OF RARE EARTHS, YTTRIUM, BARIUM, STRONTIUM, AND CESIUM

Melt refining of synthetic EBR-II alloy in oxide crucibles at temperatures between 1200 and 1400 ts C under an inert atmosphere resulted in a separation of rare-earth elements, yttrium, and alkaline-earth elements from ingot fractions. The rate of cerium removal is shown to behave as a first-order reaction. Cesium is quantitatively volatilized from highly irradiated uranium fuels refined at 1200 ts C for 4 hr. (auth)
