This report provides the results of our investigation about the new harmonized concept of hard energy path and soft energy path in the future hydrogen society, as a part of FBR cycle introduction scenario study in the JNC's "Feasibility Study on Commercialized Fast Reactor Cycle System". First, we considered that an environmental preservation policy and hydrogen utilization might be the current in the 21st century, then, investigated the supply-and-demand status of resources and energy in hydrogen society. Furthermore, the harmonized image of a nuclear fuel cycle and soft energy paths (distributed power supplies, fuel cell vehicle, chemical plant, etc.) was investigated. Nuclear fuel cycle is considered to contribute to the supply of the platinum group metals whose the increase in demand will be expected in hydrogen society in addition to production of the CO free energies (electric power, hydrogen, etc.) by nuclear energy. And the range of the supply-and-demand balance of the platinum group metals recovered from the reprocessed waste was calculated. Fufthermore, its radioactivity characteristics and the problem on the utilization of the recovered elements was evaluated. In order to propose the supply system of the resource and energy preserving the environment. We are going to study the infrastructure for the supply of recovered elements and CO free energy.
