Definitions
- Fission products may alternatively or additionally be extracted from the ionic liquid by the addition of an organic solvent. Addition of an organic species results in the precipitation of fission product compounds.
- the precipitate can be filtered from the ionic liquid and calcined to convert to oxide prior to a vitrification step. Cleaned ionic liquid can then be recycled to the electrorefiner.
- the decomposition product is separated together with at least one other decomposition product from the contaminants. Separation is effected by volatilisation during the heating process. In one embodiment of the invention the partial decomposition product is separated from the at least one other decomposition product by distillation.
- the ionic liquid is heated under reduced pressure to a temperature within the range of 200°C to 300°C.
- l-methyl-3-ethylimidazolium is heated at a temperature from 220°C to 250°C for 2-3 hours at pressures below 2mmHg.
- 1 -methylimidizole and 1 -ethylimidizole can be separated by distillation to allow for regeneration of the specific ionic liquid l-methyl-3-ethylimidazolium chloride. It should be understood that separation is not required for processes which operate on a mixture of l-methyl-3-ethylimidazolium chloride, 1,3-dimethylimidazolium chloride and 1,3-diethylimidazolium chloride.
- fission product residue is calcined to convert it into a stable waste form.
- fission product residue is reacted with boric acid to convert it into a suitable form for disposal.
