Activities in the field of partitioning of minor actinides at the Institute for Transuranium Elements in Karlsruhe
At the European Institute for Transuranium Elements, different forms of waste have accumulated over the last 15 years which contain gramme amounts of Am-241, Am-243, Np-237 and Cm-244. In view of the financial value of the minor actinides contained in the waste, equipment has been set up for their recovery. Am-241 is separated from filtrates of MOX fuel fabrication by precipitation, and Np, Am, Cm by HPLC, in water-shielded cells. The recovery of minor actinides in spent testing fuels is being developed. A group separation of actinides and lanthanides by liquid-liquid extraction is foreseen. A comparative study evaluating TRPO vs. CMPO by using high level wastes from LWR reprocessing has been made. In a cooperation with INET, Beijing, two batteries of centrifugal extractors will be set up. In order to improve lanthanide/actinide separation, a laser enhanced extraction technique is being studied.
