Abstract :
Many of the early nuclear facilities were designed and constructed in the world. The design and construction of these stations did not consider many of the necessary standards, this could cause the emergence of many uncontrollable risks. Determining the location of the nuclear power plant is considered one of the most central criteria in the decision to establish nuclear power plants, as the selection of the location requires a comprehensive review of all the influences that may affect the nuclear plant. This paper will review the criteria for locating nuclear power plants and contemporary developments which can be considered in the appropriate decisions - making process to determine the appropriate sites for the construction of nuclear power plants. To achieve the objectives of this study, a review of the nuclear events that occurred from the use of nuclear weapons in 1945 AD to the Ukrainian crisis in 2022 will be conducted. Through these reviews, the most important criteria will be inferred and with an indication of the timeline for the emergence of these criteria and what new criteria can be added in the process of building and determining the location of the nuclear plants. Keywords: Nuclear Power Plants; Nuclear Accidents; Ukrainian Crisis; Hierarchical Model.
