As Probabilistic Safety Assessments (PSAs) are thoroughly conducted for the Site Operating States (SOSs)for a single unit, multi-unit Probabilistic Safety Assessments (MUPSAs) are ongoing worldwide to addressnew technical challenges or issues. In South Korea, the determination of the site operating states for asingle site requires a logical approach with reasonable assumptions due to the fact that there are 4e8operating units for each site. This paper suggests a simulation model that gives a reasonable expectationof the site operation states using the Monte-Carlo method as a stochastic approach and deterministicaspects such as operational policies. Statistical hypothesis tests were conducted so that the reliance ofthe simulation results can be guaranteed. In this study, 7 units of the Kori site were analysed as a casestudy. The result shows that the fraction of full power for all 7 units is nearly 0.45. For situations whenmore than two units are not in operation, the highest fraction combination was obtained for PlantOperation State (POS) 8, which is the stage of inspection and repairment. By entering various siteoperation scenarios, the simulation model can be used for the analysis of other site operation states.
