초록

1978년에 고리 1호기의 건설이 완공된 이래로 원자력 발전 플랜트의 건설 프로젝트는 국내 외로 점차 확대되고 있다. 그러나 일부 원자력 발전 플랜트의 건설 현장에서는 리스크 관리 능력의 부족으로 인하여 공기 지연과 공사비 손실의 문제점들을 가지고 있다. 특히, 원자력 발전 플랜트 내 원자로격납건물의 시공은 타 시공 단계에 비해 긴 공정기간으로 인하여 전문기술과 대규모 자원이 요구됨에 따라 많은 리스크 요인들이 산재될 수 있다. 따라서 원자로격납 건물의 시공에서 예상되는 리스크 요인들을 분석하여 전체 프로젝트의 안정적인 수행 방향을 제시하는 연구가 필요하다. 그러므로 본 연구는 원자로격납건물 시공의 리스크 요인들을 평가하고자 한다. 이를 위하여 본 연구는 36명의 소수 전문가 집단을 대상으로 하는 설문조사방법을 활용하였다. 24개의 리스크 요인들은 공정, 원가, 안전, 품질을 기준으로 분류되었으며, 이에 대한 평가 결과는 계층 분석방법을 활용하여 분석하였다. 이를 바탕으로 각 기준별로 분류된 리스크 요인들은 중요도와 우선순위를 산정하고 원자력 발전 플랜트의 시공 리스크 요인을 분석하는데 계층분석 방법의 적용성을 확인하였다. 본 연구의 결과는 원자로격납건물의 시공 단계에서 리스크 관리를 위한 기초 자료로 활용될 수 있을 것이다.

Since the construction of Kori 1 was completed in 1978, the construction projects for nuclear power plant are increasingly expanded into domestic and foreign sites. However, some of construction sites of nuclear power plant have the problems of process delay and cost loss due to lack of ability of risk management. The construction of reactor containment building in nuclear power plant is especially dotted with many risk factors because it needs professional skills and large-scale resources due to long duration compared with different construction phase. Therefore, it needs the study that analyzes risk factors expected in construction of reactor containment building and suggests way of stable performance of projects. So, this study assesses risk factors of construction of reactor containment building. For the objectives, this study uses survey for group of minority specialists of 36 experts. The risks of 24 factors is classified by criterions of process, cost, safety, and quality and the results of assessment is analyzed by analytic hierarchy process. As the results, the importance and priority of risk factors classified by each criterion were calculated and the applicability of analytic hierarchy process was identified to analyze risk factors of nuclear power plant construction. These will be baseline data for risk management in construction phase of reactor containment building.
