In order to improve the data accuracy of neutron-capture cross sections of minor actinides (MAs) and long-lived fission products (LLFPs), a new experimental instrument named "Accurate Neutron-Nucleus Reaction measurement Instrument (ANNRI)" has been constructed in the Materials and Life science experimental Facility (MLF) at the Japan Proton Accelerator Research Complex (J-PARC), and measurements of neutron-capture cross sections of MAs, LLFPs and some stable isotopes with high intensity pulsed neutrons have been started. The analyses for Cm, Cm, Am and Np were finished; those for I, Pd, Tc, Zr and some stable isotopes are in progress. These results will make significant contributions in the field of developing innovative nuclear systems.
