| titleOfInvention | Method for decontaminating metal surface in cooling system of nuclear reactor |
| abstract | A method for decontaminating a metal surface in a cooling system of a nuclear reactor includes performing a plurality of processing cycles, and each processing cycle includes an oxidation step in which a metal oxide including a radioactive isotope on a metal surface is contacted with an aqueous solution of a permanganate oxidant ; After the oxidation step is a decontamination step, wherein the metal oxide is contacted with an aqueous organic acid solution, the organic acid is selected from the group consisting of oxalic acid, formic acid, citric acid, tartaric acid, picolinic acid, gluconic acid, glyoxylic acid and the above mixture Group, causing at least a portion of the metal oxide to dissolve with the radioisotope; and a cleaning step in which at least the radioisotope is fixed to the ion exchange resin; wherein the oxidation step includes the same or different processing cycles, and at least one acidic oxidation step and at least one are sequentially performed An alkaline oxidation step; and a plurality of processing cycles therein including at least one processing cycle including a high temperature oxidation step, wherein the permanganate oxidant solution is maintained at at least 100 ° C, and at least one reactor coolant pump is used to circulate and heat the main ring Oxidation solution in the circuit, for waste heat removal system Control during the high temperature oxidation step an oxidant solution temperature. |
