We are developing 30 MeV X-band (11.424 GHz) electron linac based neutron source for nuclear data study for the Fukushima nuclear plant accident. We should now accumulate more precise nuclear data of U, Pu, and MA (Cm, Am, etc.) especially in epithermal (0.1-10 eV) neutrons for the near future analysis. We are going to install the neutron source into the core space of the experimental nuclear reactor Yayoi, which is now under the decommission procedure. We already have a basic design of 50 kW class S-band linac based neutron source for future on-site analysis in Fukushima and commercial medical RI production.
