<p>In the reprocessing of irradiated nuclear fuel, fluorination of the fuel is carried out by feeding the fuel to an ionised gas plasma and then contacting the resultant excited species with a fluorinating agent, for example, fluorine, so as to effect fluorination. The ionised gas plasma is an inductively-coupled plasma or a microwave plasma, and the fuel is fed to the plasma in the form of a slurry or a powder fluidised by a gas. Where the slurry is formed from LWR fuel, a variety of volatile and involatile fission product fluorides and actinide fluorides is produced, so enabling the separation of UF6 from the involatile fission product fluorides.</p> |
