Decontamination activities to remove radioactive corrosion products present as surface contaminationare very important in terms of worker exposure management. In addition, it is deemed necessary to select adecontamination method that takes into account the type of compound during decommissioning. Chemicaldecontamination technology is widely used as a decontamination method to remove contaminants stuck to the surfacewhen decommissioning a nuclear power plant, and physical decontamination technology is used as a supplement oralternative to chemical decontamination. The types of compounds in possible corrosion products were derived asconsiderations for selecting chemical decontamination technology. The evaluation target was alloy steel, which is thematerial of the main components of the primary system, and information on the main components was referred tothe Mill Test Certificate data. Since the coolant system uses light water (H2O), it was considered as an environmentcontaining hydrogen (H) and oxygen (O) in addition to the components that make up the metal material, and wasevaluated using the TPP Diagram module in the HSC Chemistry code.
