When the nuclear energy capacity of Japan is reduced, the characteristics of nuclear energy systems are assessed based on the nuclear fuel cycle schemes with the suppositions of long-term nuclear energy scenarios including after 2030. The deployment of fast reactors and recycling of spent fuels have enough merits from the viewpoints of spent fuel management and radioactive waste management according to the assessment in this study.

Plutonium balance of quality and quantity and an increase of MOX spent fuel are important factor for the future fuel cycle. In order to substantiate these countermeasures, we examined the solution by the fast reactor cycle and evaluated the effectiveness of introducing the fast reactor cycle from the viewpoint of nuclear fuel cycle material balance analysis. In this report, we report the possibility of multiple recycling of light water reactors, the effect of reducing the MOX fuel storage amount when using light water reactors and fast reactors in combination, and the effective use of geological disposal facilities.

Around 2050, which is a target year for carbon neutrality, the total population of Japan is predicted to decline to the level of the high economic growth period of the 1960s, and the working-age population ratio is also predicted to decrease from about 70% to about 50%. Since there is concern that economic and industrial activities will slow down due to this impact, measures to maintain the technological base and supply chain in the nuclear industry were examined and evaluated from a perspective of nuclear fuel cycle scenario analysis.
