Uranium Isotope Exchange between Uranium Hexafluoride and Uranium Pentafluoride
Journal of Nuclear Science and Technology, 1995 To aim at a better understanding of the uranium isotope exchange reaction between gaseous UF6 and solid UF5 experiments were done with natural UF6 gas and solid UF5 containing 3% 235U under different pressures of UF6. The experimental results suggest a two-process reaction with an initial rapid increase of 235UF6 in the gas phase followed by its slight
