| Sumario: | South Africa is being confronted with an irregular power supply, leading to persistent load shedding due to aged and unreliable coal-fired power plants. Connected with coal as a generating source for electricity from fossil fuels are environmental concerns such as emissions of greenhouse gases and climate change impacts. Nuclear energy can allay the country’s dependence on coal as a source of energy. This article, therefore, reviews the feasibility of nuclear energy using a multicriteria analysis technique. A combination of Strengths, weaknesses, Opportunities, and Threats (SWOT) analysis and Analytical Hierarchy Process (AHP) was used to evaluate the external and internal factors that could either positively or negatively affect the country’s nuclear energy expansion drive. From the analysis, the country’s enabling laws and regulatory framework recorded the highest score of 39.2% under the strengths for the sector. In the case of the weaknesses, the high cost of construction and long construction framework recorded the highest weight, of 50.47%. Energy export and demand under the opportunities recorded a weight of 52.09%, ranking it as the highest opportunity for the sector. Seismic events were identified as the biggest threat for nuclear power expansion in the country, and the experts assigned a weight of 42.5% to this factor. |
