Partitioning of neptunium, technetium and iodine
The partitioning of neptunium (Np), the most abundant but least radioactive of the minor actinides, would be relatively quick to do. Studies carried out at the ATALANTE pilot facility have shown that, by making minor changes to the PUREX process used at La Hague for extracting uranium and plutonium, it would be possible to partition this actinide. It would also be possible to separate the iodine (I) and the technetium (Tc), isotopes I-129 and Tc-99 of which are long-lived fission products.
