The energy resolved neutron imaging system RADEN, installed at the Japan Proton Accelerator Complex (J-PARC), utilizes short-pulsed neutrons in the energy range from meV to keV by means of the time-of-flight method. The wide neutron energy range makes it possible to adjust neutron attenuation of a sample to suit a particular measurement by selecting the neutron energy range. The Core Material Melting and Relocation (CMMR) experiments have been performed to investigate core melt accidents in the Fukushima-Daiichi (1F) Nuclear Power Plant. Some amount of boride was found to be contained in simulated melted core material. The authors show the status of the development of a method utilizing energy-resolved neutrons, and demonstrate some measurements of boron-containing samples, including simulated melted core material.
