Research Highlights

  • We have developed a Langevin model for nuclear fission with 4 shape-degrees of freedom for the first time, and now going to apply it to understand various aspects of fission phenomena
  • We have developed a microscopic method to describe nuclear fission in terms of anti-symmetrized molecular dynamics, and are now able to validate many assumptions on nuclear fission from the viewpoint of a theory based on nuclear force
  • We proposed a new scheme to transmute long-lived fission products populated in nuclear power reactors to shorter (or stable) ones in terms of fast reactors. This projects was approved by MEXT starting from 2016 with a funding of 380M JPY for 4 years.
