한국어 초록

국내 최초의 상업원전인 고리1호기가 2017년 6월에 영구 정지되었다. 고리1호기 해체를 시작으로 한국은 원전 해체시장에 본격적으로 발을 내딛는다. 원자력발전소 해체를 위해서는 고려해야 할 사항들이 많으며, 방사선환경영향평가 또한 그 중 하나이다. 방사선환경영향평가의 목적은 주변주민의 건강과 안전을 도모하기 위해, 해체 전 및 해체 중에 해당 시설에서 방 출되는 방사성물질로부터 주변주민이 받는 피폭방사선량이 규제 제한치를 초과하지 않음을 확인하는 것이다. 현재 국내에는 해체시 방사선환경영향평가서를 작성하는데 필요한 세부지침이 미비한 상황으로, 다수의 원전 해체 경험을 보유한 미국의 해체시 방사선환경영향평가서를 비교·분석하여 국내 상황에 맞는 해체시 방사선환경영향평가 방안을 개발하였다.

영어 초록

Kori unit 1, the oldest commercial nuclear power plant in South Korea, was permanently shut down in June 2017. There are a lot of things to consider in decommissioning nuclear power plants, and one of them is the radiological environmental impact assessment. Performed to promote the health and safety of residents around the nuclear power plant, radiological environmental impact assessment aims to confirm that off-site radiological dose from radioactive material released from the facility does not exceed the regulatory criteria. There are three main parts of environmental impact assessment: predecommissioning environmental monitoring, environmental monitoring during decommissioning, and impact on nearby residents. At present, although the Korea Nuclear Safety Act stipulates that radiological environmental impact assessment resulting from decommissioning should be carried out, the details have not been specified. Therefore, this paper compares and analyzes guidelines for evaluation of radiological environmental impacts of nuclear power plants overseas, and presents a draft on the assessment of radiological dose resulting from decommissioning according to the Korean situation.
