Spent Resin Treatment Test in the ATR Fugen Nuclear Power Station Using Low Pressure Oxygen ICP

Low-pressure oxygen plasma processing using ICP (Inductively coupled plasma) is the technology that takes volume reduction and stabilizing treatment of an organic material such as ion exchange resin mildly. We evaluated, for example, treatment performance such as the volume reduction, the weight reduction, and γ specter, H-3,C-14 for the spent ion exchange resin which has actually been produced in the ATR Fugen power station. As a result, a volume reduction rate was achieved not less than 90% (1/10), and a weight reduction rate not less than 95% (1/20). Co −60 was held not less than 0.998 in a processing chamber. In addition, distribution to an effluent gas was not more than 10⁻⁶.
