Abstract

Leading waste disposal countries, such as Sweden, Switzerland, and the United Kingdom, conduct safety assessments across all stages of High-Level Radioactive Waste Deep Geological Disposal Facilities-from planning and site selection to construction, operation, closure, and post-closure management. As safety assessments are repeatedly performed at each stage, generating vast amounts of diverse data over extended periods, it is essential to construct a database for safety assessment and establish a data management system. In this study, the safety assessment data management systems of leading countries, were analyzed, categorizing them into 1) input and reference data for safety assessments, 2) guidelines for data management, 3) organizational structures for data management, and 4) computer systems for data management. While each country exhibited differences in specific aspects, commonalities included the classification of safety assessment input data based on disposal system components, the establishment of organizations to supply, use, and manage this data, and the implementation of quality management systems guided by instructions and manuals. These cases highlight the importance of data management systems and document management systems for securing the safety and enhancing the reliability of High-Level Radioactive Waste Disposal Facilities. To achieve this, the classification of input data that can be flexibly and effectively utilized, ensuring the consistency and traceability of input data, and establishing a quality management system for input data and document management are necessary.

스웨덴, 스위스, 영국 등 폐기물 처분 선도국들은 고준위방사성폐기물 심층처분시설의 계획, 부지선정, 건설, 운영, 폐쇄, 그리고 폐쇄 후 관리 전 단계에서 안전성평가를 수행하고 있다. 안전성평가는 각 단계에서 반복적으로 이루어지며, 장기간에 걸쳐 다양하고 방대한 양의 데이터를 생성하므로, 안전성평가 자료를 위한 데이터베이스를 구축하고 효과적으로 관리하기 위한 자료관리체계를 구축하는 것이 필수적이다. 본 연구에서는 폐기물 처분 분야에서 선도적인 국가의 안전성평가 자료관리체계를 1) 안전성평가 입력 및 참조자료, 2) 자료관리 지침, 3) 자료관리 조직, 그리고 4) 자료관리 전산시스템으로 구분하여 분석하였다. 각 국가는 특정 부분에서는 차이를 보였지만, 안전성평가 입력자료를 처분 시스템 구성 요소를 기반으로 분류하고, 이를 제공, 사용, 관리하는 조직을 설립하며, 지침 및 매뉴얼에 따라 품질관리 체계를 구현하는 등 공통적인 특성을 보이고 있다. 이러한 사례들은 고준위방사성폐기물 처분시설의 안전성을 확보하고 신뢰성을 향상시키기 위해 효과적으로 데이터 관리 시스템과 문서 관리 시스템을 구축하는 것이 중요하다는 것을 시사한다. 이를 위해서는 유연하게 활용 가능한 입력자료의 분류, 입력자료의 일관성과 추적성 보장, 그리고 입력자료와 문서관리를 위한 품질관리 체계를 수립하는 것이 필요하다.
