Nuclear power can be considered to be an extremely important energy source that should be utilized for a carbon neutral society. However, a major challenge in sustainable use of nuclear power is the problem of radioactive waste disposal. Especially in a country with a small land country like Japan, recycling of geological disposal sites is a major issue. Needless to say, the handling of high-level liquid waste is an important issue in this regard. On these backgrounds, the Harima Synchrotron Radiation RI Laboratory of JAEA (SPring-8), started to study the feasibility of radiation power generation as a bridge technology for the management of long-lived alpha-nuclides such as Am on the ground. We will introduce the initial experiments on power generation from 60 keV gamma-ray of Am, conceptual design of a new separation method by oxidation of Am with multiphoton excitation, and future research development in this presentation.
