CN-275-88 The Impact of Adding Two Nuclear Reactors to Saudi Arabia National Grid in Reduction of Carbon Dioxide Emissions Ezzat Elmoujarkach 1 , Yahya Alzahrani 1 , Mohammed Siddig 1 , Abdulsalam Alhawsawi 1 1 King Abdulaziz University – Department of Nuclear Engineering, Jeddah, Saudi Arabia Corresponding Presenter: Ezzat Elmoujarkach Abstract In this work, an analytic study has been conducting to carry out the effect of adding two nuclear power plants to the total mix power in Saudi Arabia electrical national grid. Ultimately, Saudi Arabia planning to bullied two nuclear reactors to be operational in 2030 according to the country vision 2030. The average estimate of 1000-1600 MWh is expected of each nuclear reactor. The total CO2 emission of Saudi Arabia is calculated to be 815.72 million tons per year with current estimations that this emission will be increased with the years. Furthermore, introducing two nuclear reactors to the national grid will help in the reduction of the depending on the country over the fossil fuel reducing the total CO2 emission by 1.07%. This paper presents a detailed of the effect of a power plant in the reduction of CO2 in the country. Introduction With the advancement of technology, our lives have been more dependent on energy from powering up factories, charging phones, to communicating with each other. The demand for energy has increased drastically in the past few years, and predictions show that this demand will get higher, as shown in Figure (1). This increment is believed to be caused by the global population growth and changing the lifestyle that results in higher energy demand. Figure 1 The increase in energy demand worldwide [1]
