Abstract

The article presents a method for comparing NPP siting sites using methods of expert evaluation of parametric criteria. For a generalised assessment of sites, the following factors with corresponding criteria are proposed: economic factor: criteria — “Energy transmission networks”, “Operating costs», “Impacts on the economy»; social factor: criteria — “Transport network”, “Legal aspects”, “Impact of tourism”, “Land ownership rights”, “Historical sites”, “Public recognition”: safety factor: criteria — “Geology and seismology”, “Population density”, “Impacts on the location area”, “Cooling water”, “Meteorology”, “Hydrology”, “Topography”, “Land use”, “Proximity to wetlands”, “Evacuation routes”, “Proximity to hazardous facilities”. In this case, the expert assessment is carried out by each expert using the method of pairwise comparison of preferences, the criteria of alternatives are considered by experts comprehensively and taken into account in the pairwise comparison. This method allows for the assessment and comparison of new nuclear objects siting sites in a short time without significant financial costs. The example of the AP1000 new reactor construction project shows the process of comparing sites out of three proposed ones. The article presents an approach to comparing NPP siting sites using methods of expert evaluation of parametric criteria. At the initial stage of comparison, the proposed method is used for a generalised analysis of alternatives, without a detailed consideration and comparison of all criteria by relevant groups of factors — technical, technological, socio-economic, etc. At the same time, each expert makes an expert assessment by the method of pairwise comparison of preferences, the criteria of alternatives are considered by experts comprehensively and taken into account in the pairwise comparison. This method allows conducting a preliminary generalised comparative expert analysis and formulating recommendations for the assessment of new reactor siting sites in a short time without significant financial costs, based on numerical characteristics. Using the example of the AP1000 new reactor construction project, the paper demonstrates the comparison process based on numerical assessments of three proposed sites. The analysis shows that alternative A1, the Khmelnytskyi NPP site, is the best option.
