| abstract |
The invention relates to a process for separating together all the actinides (III), (IV), (V) and (VI) present in a strongly acidic aqueous phase of the fission products, and in particular lanthanides, being also in this phase, by means of two extractants operating in disjoint chemical domains.Applications: reprocessing of irradiated nuclear fuels, in particular to recover plutonium, neptunium, americium, curium and, possibly, uranium present at trace state, grouped but selective for lanthanides, from a solution for dissolving an irradiated nuclear fuel, downstream of a uranium extraction cycle. |
