| Abstract(in English) | The mixed oxide (MOX) fuels are produced from the Pu/U mixed nitrate solution obtained from the spent nuclear fuel as a part of the nuclear fuel cycle. In Japan, the water evaporation and the de-nitration of the Pu/U mixed nitrate solution have been carried out by using the microwave heating. In this process, however, further improvements of heating uniformity and efficiency are eagerly required for the mass production. The electric constants of the Pu/U mixed nitrate solution change along with the phase transition caused by heating. Therefore, in microwave heating, it is very important to know the power absorption characteristics of the Pu/U mixed nitrate solution in each phase state. In this study, the electric power absorption of the medium in each phase state is investigated by using the FDTD method. |
