摘要： The invention resides in an apparatus for the decontamination of radioactivated metallic waste by the electrolytic oxidation-reduction with an aqueous nitric acid solution containing trivalent cerium ions, i.e. the step of converting the trivalent cerium ions into tetravalent cerium ions through electrolytic oxidation and the step of dissolving the surface layer of the radioactivated metallic waste by oxidizing it with the electrolytic solution now vested with the oxidative power of the freshly produced tetravalent cerium ions and, at the same time, effecting regeneration of the tetravalent cerium ions. The main objects of this invention are to provide a high decontamination efficiency and suppression of the amount of secondary waste to be generated to the minimum by the apparatus which is capable of thoroughly dissolving the surface layer of the object under treatment without reference to size and shapes, the very factors that prevent the conventional methods of decontamination from fulfilling their functions indiscriminately, thereby lowering the level of radioactivity to a point where the object will be handled as safely as ordinary industrial waste.
摘要翻译：本发明涉及一种用含有三价铈离子的含硝酸水溶液进行电解氧化还原的放射性活化金属废物去污的装置，即通过电解氧化将三价铈离子转化成四价铈离子的步骤，通过用现有的新产生的四价铈离子的氧化能量赋予的电解液氧化放射性活化的金属废物的表面层，并同时进行四价铈离子的再生来溶解。本发明的主要目的是通过能够彻底溶解被处理物体的表面层而不参考尺寸和形状的设备，提供高的去污效率和抑制二次废物产生的最小量。，防止常规消毒方法不加区别地实现其功能的因素，从而将放射性水平降低到与普通工业废物一样安全处理的程度。
