Nuclide separation technology and engineering application of radioactive oil for NPPs
Radioactive oil is one of the organic "difficult wastes" produced by the operation of nuclear power plants.
This study aims to develop a nuclide separation and treatment technology for radioactive waste oil and explore engineering application.
First of all, a set of radioactive oil nuclide separation and purification treatment engineering equipments was developed and applied to obtain test samples collected from one NPP. Then a nuclide separation and purification process based on the oxidative aging method were developed. Finally, the high-purity germanium for nuclide γ spectrometer was employed to measure 58Co, 60Co, 54Mn, 110mAg, 137Cs, 134Cs, 124Sb, 125Sb, 59Fe, 95Zr, 95N, etc., γ nuclides, low background liquid scintillation counter was applied to the measurement of 3H and 14C, and high sensitive automatic liquid scintillation counter was used to measure 55Fe and 63Ni. Total α and total β were obtained by using low background α/β measuring instrument.
