1.Advanced ORIENT Cycle Under the Adv.-ORIENT Cycle concept where spent nuclear fuel is recognized as artificial vein of ore, separation and utilization researches have been carried out for rare metal fission products and all of the actinides.In the concept, REs, from 4f/5f separation, were nothing radioactive wastes but be the secondary resources.Tertiary pyridine resin (TPR), composing a nitrogen atom in six-membered ring, was successfully applied for 4f/5f separation using MOX spent fuel irradiated (143.8GWd/t) at the fast experimental reactor "Joyo".Catalytic electrolytic extraction (CEE), utilizing under potential deposition with forming of undissolvable metal solid solution in acidic media, can effectively separate PGMs,Tc and Re from HLLW.Those co-deposits were, dense and mechanically stable, showing electrochemically high catalytic reactivity on electrolytic H2 production.2.Après ORIENT Après ORIENT will newly propose transmutation of highly radioactive FPs into valuable, but non-radioactive rare metal elements by (n,γ) reaction succeeded by β-decay,ZFPA (n,γ) Z FPA+1 → Z+1NRMA+1 + β-Current transmutation target FP elements are Tc, Ru, Rh and some REs.Preliminary calculation with the conditions of even at higher energy fast neutron spectra with high neutron flux suggests the high transmutation possibility for the pairs of FPTc→Ru as well as among REs hike FPTb→Dy.In the case of transmutation of FP Ba to La (RE), optimization study is underway.
