A protective oxide layer forms on the material surfaces of a nuclear power plant during operation due to high temperature. This study addresses the challenge of developing effective chemical decontamination technology for domestic CANDU-type reactors, specifically focusing on the pressurized heavy water reactor (PHWR) system. The Korea Atomic Energy Research Institute has previously introduced the 'HyBRID' (hydrazine-based reductive metal ion decontamination) process for pressurized water reactors, which notably omits the use of organic acids or chelating agents. To adapt and enhance this technology for PHWR systems, we investigated the role of copper (Cu) in the dissolution of magnetite, a prominent oxide layer in nuclear power plants. Our findings reveal that the redox cycle of copper in conjunction with hydrazine and magnetite demonstrates a notably effective dissolution behavior. This study presents a crucial step toward optimizing decontamination procedures in nuclear reactors. [ABSTRACT FROM AUTHOR] |
