Study of volume reduction technique for ion exchange resin using non-thermal inductively coupled plasma

摘要

The amount of radioactive ion exchange spent resins in the water cleaning systems of nuclear power plants is increasing. In this experiment, we examined the volume reduction technique for SKN-1 bead ion exchange resin using the non-thermal ICP(Inductively Coupled Plasma). Experimental results indicate a volume reduction ratio of 96% after 5 hours of plasma treatment with new SKN-1 and the amount of plasma exhaust gas was about two to three times as much as the volume of oxygen. The amount of cobalt scattered to theexhaust system was a mere 0.002%~0.005%. Thus, we obtained good results in effectively reducing the volume by non-thermal plasma.
