| 摘要 |
<p>The present invention relates to a method for separating together all the actinides (III), (IV), (V) and (VI) present in a highly acidic aqueous phase from the fission products, especially lanthanides, also present in said phase using a solvating extractant in a salting medium. Application in the treatment of irradiated nuclear fuel, mainly for recovering plutonium, neptunium, americium, curium, and optionally uranium present as traces, in a grouped manner but selectively regarding lanthanides, from a dissolution solution of an irradiated nuclear fuel downstream from a uranium extraction cycle.</p> |
