Abstract
Molten chloride salt fast reactors (MCFRs) will require UCl₃ dissolved in molten salt mixtures as fuel for nuclear fission. For infusing the salt with UCl3, bubbling HCl into NaCl-CaCl₂ in contact with U metal was investigated. The reaction was run up to 9 h and yielded U concentration up to 0.652 wt.%. Open circuit potential between a W electrode and Ag/AgCl reference electrode yielded a potential consistent with uranium existing as U(III) in the salt. This demonstrates that HCl can be a very effective chlorinating agent to infuse MCFR fuel with UCl₃ starting from U metal.
