Abstract

It was shown that when irradiated with neutrons, uranium hexafluoride decomposed to intermediate uranium fluorides (presumably UF5 and fluorine).The rateof decomposition was∼G = 0.5 mole/l00 ev or 0.21mole/hr per kw of power liberated in the gas. It was also shown that in addition to dissociation of UF6 during irradiation there was also recombination of the decomposition products. As a result, equilibrium concentrations of fluorine and UF6 are set up, and these depend on the strength of the radiation. When mixed with fluorine, uranium hexafluoride is a radiation-stable compound even at room temperature and may be used as a fuel in a nuclear reactor.
