Abstract

The purpose of this study is to deduct the structural damage / work process risks factors which can be occurred during the decommissioning in the NPP containment concrete structure. To achieve these purpose, risk profile specified in the construction industry is analyzed, and the work process of NPP decommissioning and the construction project were matched based on the similarity of each works. Accordingly, human and physical risk factors are classified. Finally, the risk associated with the building structure and work process was classified as per their process activities, and risk typology explaining the disaster which put the structure, equipments, machine and workers in serious danger was developed.

건설해체공사와 유사한 특성을 갖는 원전 제염해체공사에서 구조적 리스크 관리는 매우 중요하다(DOE). 하지만 제염해체작업 중 발생할 수 있는 구조적 재난재해 및 위험요소는 크게 고려하지 않고 있다. 이로 인해, 구조적 재난 및 재해에 의해 발생할 수 있는 작업자 리스크 역시 체계적으로 정립되어 있지 않다. 또한, 재난 및 재해 그리고 리스크 분류체계는 작업의 특성(작업프로세스, 활용장비, 작업 위치 등)별로 분류되어 있지 않아 실제 해체공사를 위한 매뉴얼로 활용하기에 무리가 있다. 따라서 차폐 콘크리트 구조물 제염해체공사의 건설해체공사와의 유사성을 기반으로 작업의 특성별로 분류한 리스크를 도출하는 것은 원자력 발전소 해체공사 리스크 관리에 필수적으로 판단한다.
