Abstract: A chemical decontamination reagent containing a reducing agent, a reductive metal ion, and an inorganic acid is provided to remove a radioactive oxide layer on a metal surface. The reagent can dissolve the radioactive oxide layer on the metal surface effectively at a relatively low temperature and enables a simple process of contacting the reagent to the radioactive oxide, thus economically effective in terms of cost and time required for the process. Since the decontamination does not use a conventional organic chelating agent such as oxalic acid, but the reducing agent as a main substance, the residuals of the reducing agent remained after decontamination can be decomposed and removed with an oxidizing agent. Due to the easy decomposition with the chemical decontamination reagent, secondary wastes can be minimized and the radionuclides remained in the decontamination reagent solution can be removed effectively.

Abstract translation: 提供含有还原剂，还原性金属离子和无机酸的化学去污试剂以去除金属表面上的放射性氧化物层。 试剂可以在相对较低的温度下有效地溶解在金属表面上的放射性氧化物层，并且能够使试剂与放射性氧化物接触的简单过程，从而在该方法所需的成本和时间方面经济上有效。 由于去污不使用常规的有机螯合剂如草酸而是还原剂作为主要物质，所以在去污后残留的还原剂的残留物可以用氧化剂分解和除去。 由于化学去污剂容易分解，二次废物可以最小化，并且可以有效去除残留在去污试剂溶液中的放射性核素。

Abstract: The present invention provides an oxidative decontamination reagent for removal of the dense radioactive oxide layer on a metal surface, which comprises an oxidizing agent, a metal ion, and an inorganic acid. The oxidative decontamination reagent of the present invention is characteristically prepared by adding a metal ion to the conventional oxidative decontamination reagent containing an oxidizing agent and an inorganic acid. When the oxidative decontamination reagent of the present invention is used, electric potential of the metal parts of the primary system of the nuclear power plant can be regulated as passive potential owing to the added metal ion during the oxidative decontamination of the primary metal part of the nuclear power plant. Therefore, by maintaining electric potential of the metal part as passive potential, local corrosion can be inhibited and at the same time secondary waste can be significantly reduced.
