Many developed countries have focused on the nuclear energy among all the available energy sources in world because of its low pollution rate in comparison with the others. Nuclear power plant (NPP) site selection is a key phase of an NPP construction process and can have a positive effect on the level of safety and operational cost of the NPP during its lifetime. There are several criteria for selecting best site for an NPP that are described in International Atomic Energy Agency’s (IAEA) safety standards and guidelines of nuclear regulatory bodies located in different countries. In current study, a three-stage approach has been developed for selecting best sites for NPPs. In the first two stages, some areas have been put aside, based on exclusion and avoidance criteria respectively using ArcGIS software. In the third stage, based on suitability criteria, a developed mathematical programming model suggests best sites among candidate sites achieved in stage one and two, which have been considered in the objectives and chance constraints. Given that dependency of results on land parameters, Bushehr Province, which the only NPP in Iran is operating in that province, has been selected as the region of interest (ROI). For resolving the uncertainty, it’s assumed that stochastic parameters have normal distributions. Furthermore, in order to solve the bi-objective model, Ԑ-constraint method is used in GAMS framework. Results show potential of the province in energy field. By using GIS and decreasing number of candidate sites, the complexity of the mathematical model has been decreased and there is no need to use heuristic or metaheuristic algorithms, which don’t assure optimal solutions. Also, by using ArcGIS software, the area has been evaluated continuously and distance-related criteria have been analyzed with high degree of accuracy. Following the results achieved by solving mathematical model, increasing safety and increasing capacity of electricity production, have been analyzed from economic point of view. Some of the innovations in the current study are consideration of several criteria to site NPPs and making the problem practical; developing a three-stage approach and a mathematical model in the study area and consideration of a province in Iran for case study.
