Abstract

Abstract: Kori 1, the first commercial reactor in Korea, was permanently shut down in 2017 and is preparing for decommissioning in the mid‐2020s. Although Kori 1 is shut down, some radiation sources remain in the system; as such, the dismantling workers are exposed to radiation until decommissioning is completed. Unexpected radiation events have been reported in some decommissioning nuclear power plants (NPPs), which resulted in additional radiation exposure to workers and significant financial losses due to delays in the decommissioning schedule. Hence, an appropriate radiation protection program must be established to minimize radiation exposure as well as the economic burden. In this study, radiation doses from precedent decommissioning NPPs worldwide are compared with those estimated from Kori 1 to determine dose reduction measures that can achieve radiation exposure as low as reasonably achievable to decommissioning workers. Abstract : Radiation doses from precedent decommissioning nuclear power plants worldwide are compared with radiation doses estimated from Kori 1, the first decommissioning‐planned reactor in Korea, to determine dose reduction measures that can achieve radiation exposure that is as low as reasonably achievable to decommissioning workers.
