A multi-regression model was developed to estimate the decommissioning cost for Kori unit 1 using foreign nuclear power plant (NPP) decommissioning cost data. First, the decommissioning cost data were collected for 13 boiling water reactors and 16 pressurized water reactors and converted into the values as of November 2019. Then, for the regression model, the decommissioning cost was chosen as the dependent variable, and two variables were selected as independent variables: a contamination factor that was designed to reflect the operational characteristics of the decommissioned NPP and the decommissioning period. A statistical package in the R language was used to derive the regression model. Finally, the regression model was applied to estimate the decommissioning cost for Kori unit 1. The estimated decommissioning cost for Kori unit 1 was 663.40~928.32 million US dollars (782,812~1,095,418 million Korean won).

The metal waste generated during nuclear power plant decommissioning constitutes a large proportion of the total radioactive waste. This study investigates the current status of domestic and international regulatory requirements for clearance and the clearance experience of domestic institutions. The RESRAD-RECYCLE code was used for analyzing the clearance of the metal wastes generated during actual nuclear power plant decommissioning, and assessment of the exposure dose of twenty-six scenarios was carried out. The evaluation results will be useful in preliminary analysis of clearance and recycling during nuclear power plant decommissioning. As a next step, the effects of reducing disposal costs by clearance can be studied.

한국원자력연구원은 연구로 1, 2호기와 우라늄변환시설의 해체활동에서 얻어진 해체 경험과 그간에 쌓인 해체활동에 관한 정보 그리고 해체 대상 시설의 특성자료를 통하여 해체 작업 시 발생하는 유닛 생산성(Unit Productivity)을 자동으로 산출하는 시스템(DEWOCS)을 개발하였다. DEWOCS를 통한 해체작업시 발생하는 유닛의 해체작업 생산성 평가 인자 값은 해체 엔지니어링 시스템의 개발 및 향후 이루어질 원자력발전소를 비롯한 원자력시설의 해체 사업에서 계획 및 해체 설계에 기초자료로써 활용될 것이다.

원자력 발전소의 해체는 방대한 방사성폐기물을 일시적으로 발생시킬 뿐만 아니라 원전 건설비용의 10% 에 해당하는 많은 비용이 소요된다. 또한 해체 부지의 재활용 여부는 원전 신규부지의 확보에도 큰 영향을 준다. 대규모 원자력 추진국으로써, 원자력 발전소의 폐로조치 방안들을 체계적으로 검토하여 국내 폐로조치 방안 및 대책을 종합적으로 수립해야할 시점이 되었다. 따라서 본 연구에서는 고리 1호기를 대상으로 하여 DECON, SAFSTOR-1, SAFSTOR-2 (10년), SAFSTOR-2 (30년), SAFSTOR-2 (51.38년), ENTOMB-1, ENTOMB-2 및 ENTOMB-3등의 폐로방안을 설정하고, 미국에서 원전 폐로비용 평가에 사용 실적이 있는 전산 프로그램을 이용하여 각각의 폐로조치 방안별로 소요비용을 분석하였다. 또한 각 폐로조치 방안의 경제성 비교를 위해서 각각의 폐로조치 방안에 대해 할인된 비용의 결과를 분석하였다.

Regulatory systems for decommissioning of nuclear power plants in several countries, such as Japan, United States of America, Germany, United Kingdom, France, and Republic of Korea, are surveyed. In the survey, regulatory policies, legislations, licensing process, inspection and public involvements for decommissioning are identified and compared. Afterwards, the survey results will be utilized as a reference to establish the improvement directions of domestic regulatory system.

The licensees are to submit the decommissioning plan to regulatory body to decommission nuclear facilities. The standard review plan(SRP) of decommissioning is used to confirm and evaluate the decommissioning plan by the related regulations and standards. The licensees who want to decommission the nuclear facilities are required to submit the decommissioning plan according to Acts 31 of Atomic Energy Law. In this study, the items of reports and documents submitting to regulatory body were reviewed deliberately, and finally the major sub-items of decommissioning plan were established.
