Minor actinide (MA) transmutation by ADS (accelerator driven system) is studied for volume and radioactivity reduction of high-level radioactive waste. Candidate of the MA transmutation fuel is nitride, and it is important to acquire physical properties of the MA-bearing nitride fuel. Melting point is one of the crucial thermophysical properties, however measuring melting point of nitride fuel is difficult because of its high melting point and high radioactivity. So, this study focus on measuring melting point by combination of laser local heating and measuring spectral emissivity that is able to measure without contact and container. Considering scalability, the measuring system with spectrometer have been constructed. Samples are ZrN as the inert matrix and (Er,Zr)N solid solution as surrogate fuel material. High pressure vessel filled with pure nitrogen gas and preheating by CW laser enabls to measure with minimal oxidation and cracking by thermal shock. Measuring by spectrometer enabls to obtain thermal emission spectrum and calculate spectral radiance of sample.
