Description

Japan launched an ambitious long-term program on partitioning and transmutation (P-T) called OMEGA in 1988. Under the program PNC has being carried out its R and D activities. A check and review process based on progress made was conducted in fall 1998 by STA (Science and Technology Agency). This report was prepared to submit the state of R and D activities on partitioning by solvent extraction program in PNC for seven years (1990-1997) to STA. The paper described the progress, the results and future plans on (a) improved PUREX process for the extraction of Np with Pu by valence control, (b) improved TRUEX process for the extraction of minor Actinides and (c) other potential solvents for the extraction of other long-lived FPs from spent fuels.
