Abstract. The energy-dependence of neutrons were measured through a 3-mm thick 316 stainless-steel with homogeneous temperatures from room temperature to about 500 degrees Celsius to investigate whether molybdenum contained in 316 stainless-steel was available as a sensor material for neutron resonance thermometry. Dips in the energy spectra around the 44.8 eV resonance of molybdenum were broadened with the increasing temperature, and a calibration line from width to temperature was obtained. A neutron measurement was also carried out for a 316 stainless-steel plate having a temperature distribution. By analyzing the width of the resonance at each position, a reasonable temperature distribution was obtained. Molybdenum contained in 316 stainless-steel was found to be useful for neutron resonance thermometry.
