Safety assessment for decommissioning worker

Abstract

Nuclear power plants have a licensed lifetime. Nowadays, as the number of globally aged nuclear power plants increases, the need for research on the decommissioning of nuclear power plants is increasing. Unlike the decommissioning of other infrastructures, the decommissioning of nuclear power plants has a risk of radiation. Therefore, safety evaluation of dismantling worker about radiation is required. This study proposes a framework for evaluating the safety of workers during the decommissioning process of nuclear power plants and conducted a case study on Kori nuclear power plant unit 1 based on the proposed framework. It is expected that the risk information obtained from the evaluation can be used for developing a guideline for the dismantling worker to minimize potential risk.
