A long-term hazard of geological disposal of nuclear waste results from a few long-living radioactive nuclides which may eventually migrate back to the biosphere. This study looks at the partitioning from spent fuel of the artificial elements Tc, Np, Pu, Am and Cm. In nuclear technology two main routes for reprocessing of spent nuclear fuel are considered: pyrochemical methods as dry processing, and aqueous partitioning by continuous, counter-current liquid-liquid extraction. In this present study the capabilities of the TRPO, CMPO and DIDPA processes are compared.
