Appraisal of Nuclear Energy as an Alternative Option in South Africa’s Energy Scenario: A Multicriteria Analysis

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 c...
