Challenge of Various Developments on Nuclear Energy Study

The center is open to researchers all over the world for the collaborative studies using irradiated-materials and actinide elements, as the most leading center in the related research field for more than 50 years since the foundation.

The center has worked on a variety of research topics, understanding the degradation mechanisms of light water reactor materials, developing advanced fission and fusion reactor materials, separating and analyzing nuclear waste, the condensed matter physics of actinide compounds with 5f electrons, developing advanced nuclear fuel, and absolute dating.

The center has established research partnerships with world-class research institutes with research reactors in other countries, which promote the collaboration on neutron irraidation and the sharing of personnel and technologies. The unique characteristics of the center have been strengthened, where state-of-the-art post-irradiation experimental techniques are available very close to a hot laboratory with a huge capacity for nuclear fuel and radioisotope elements.
