Keywords:radioactive waste management, nuclear fuel cycle, nuclide separation, vitrification, waste loading, geological disposal

Following our series presentations of (1) to (6) at the 2018 spring meeting, in this paper, the relationship between the reduction of waste occupied area and concentration of Mo and PGM in response to changes in the fuel cycle conditions including nuclides separation will be investigated. And technical feasibility of Mo/PGM separation and vitrification process when it is introduced will be discussed.
