초록
The Kori-1 Nuclear Power Plant (NPP) in Korea, WH 2-Loop Pressurized Water Reactor(PWR), was permanently ceased on June 18, 2017. Prior to commencing the main decommissioningactivities, a full system chemical decontamination operation (FSCDO) of primary systems will beperformed to secure the safety of workers and to minimize the quantity of radioactive waste. In this study,the radioactivity inventory deposited in the reactor coolant system (RCS) during the decommissioning ofKori Unit 1 was investigated. The prediction results obtained from CRUDTRAN code and the measuredvalues using survey meters in fields were compared and analysed. As a conclusion, the predicted valuesusing CRUDTRAN code can be accepted with about 30% conservatism and applied for the full systemchemical decontamination operation.
