De-nitration process of Pu-U nitrate solution by the microwave heating was developed for the aim at non-proliferation of nuclear materials. After measuring the accurate temperature history in the heating process by a newly developed thermometer, the reaction mechanism was investigated at four points by using TG-DTA (Thermo gravity-differential thermal analysis) and X-ray diffraction analysis. From these results, the most likely processes on the dehydration, denitration and formation of oxide for de-nitration process of UO2(NO3)2 were suggested.
