Mixed uranium oxide and plutonium oxide powder is produced from uranyl nitrate and plutonium nitrate mixed solution by the microwave heating denitration method in the spent fuel reprocessing process. Since the microwave heating method is accompanied by a boiling phenomenon, it is necessary to fully grasp the operating conditions in order to avoid flashing and spilling in the mass production of denitrification technology for the future. In this research, it was clarified that the heat transfer coefficient became lower as the dielectric constant increased. The dominant factor of the blowing up phenomena is supposed to be generation of the innumerable bubble rather than bubble's growth.

The microwave heating denitration method is used in the spent fuel reprocessing process. In order to develop the mass production of denitrification technology for the future, it is necessary to fully grasp the operating conditions to avoid flashing and overflow phenomena of solution. In this research, the conditions of the generation of flashing are evaluated using the potassium chloride aqueous solution as the simulated solution, and the concentration of potassium chloride and the microwave output as parameters. It is found that it is difficult to occur the flashing phenomenon as the concentration of potassium chloride increases.

To investigate the influence of the dielectric properties of a solution or a spacer on the heating process of the solution, a low dielectric Teflon or an airogel having a very low dielectric property almost equivalent to air was placed as a spacer directly below the vessel. And the influence of the geometry and the dielectric properties of the sample and the spacer on the heating properties of the sample were evaluated. The heating efficiency obtained by the experiment tended to decrease as the spacer height increased. It was confirmed that the heating efficiency obtained by the electromagnetic analysis almost agreed with the experimental results by a support height of 50 mm. When Teflon was used as a spacer, microwaves entered from the bottom of the solution, whereas when airogel was used as a spacer, microwaves tended to enter from the top of the solution, and it was clarified that the dielectric characteristics of the spacer were the heating characteristics of the sample.
