ABSTRACT
Recently, plant construction throughout the world, including nuclear power plant
construction, has grown significantly. The scale of Korea’s nuclear power plant construction
in particular, has increased gradually since it won a contract for a nuclear
power plant construction project in the United Arab Emirates in 2009. However,
time and monetary resources have been lost in some nuclear power plant construction
sites due to lack of risk management ability. The need to prevent losses at nuclear
power plant construction sites has become more urgent because it demands professional
skills and large-scale resources. Therefore, in this study, the Analytic Hierarchy
Process (AHP) and Fuzzy Analytic Hierarchy Process (FAHP) were applied in
order to make comparisons between decision-making methods, to assess the potential
risks at nuclear power plant construction sites. To suggest the appropriate choice
between two decision-making methods, a survey was carried out. From the results,
the importance and the priority of 24 risk factors, classified by process, cost, safety,
and quality, were analyzed. The FAHP was identified as a suitable method for risk
assessment of nuclear power plant construction, compared with risk assessment using
the AHP. These risk factors will be able to serve as baseline data for risk management
in nuclear power plant construction projects.
