ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

At the Kyoto University Critical Assembly (KUCA), critical irradiation experiments on 237Np and 241Am foils are carried out in the neutron hard spectrum core. For nuclear transmutation of minor actinides, special attention is paid to determining 237Np and 241Am fission reaction rates and to 237Np capture reaction rates in the KUCA hard spectrum core. In the back-to-back (BTB) fission chamber, two nuclide foils (test: 237Np or 241Am; reference: 235U) are set closely to each other to measure the aforementioned fission reaction rates. Interestingly, the experimental 237Np and 241Am fission and capture reaction rates are attained by critical irradiation at low W reactor power for 1 h in the core and are successfully deduced through signals from the BTB fission chamber (fission) and the gamma-ray detection (capture) after the irradiation, respectively, together with MCNP calculations.
