اهمیت چرخه سوخت بسته در دستیابی به انرژی هسته‌ای پایدار و تجدیدپذیر در ایران

Energy security is one of the most important factors in the sustainable development of societies. Fulfillment of goals such as economic development, increasing social well-being, and improving the quality of life depend on providing energy and guaranteeing stable and reliable, clean, and affordable resources. In recent years, the use of renewable resources has received a lot of attention to diversify their energy portfolio, reduce the harmful effects on the environment, and achieve sustainable energy. From this point of view, with the proper establishment of the nuclear fuel cycle, nuclear energy can be considered as renewable and sustainable energy in the energy portfolio and compensate for the lack of non-renewable energy in the future. The purpose of this paper is to explain the importance of a closed fuel cycle in achieving sustainable and renewable nuclear energy. Also, due to the not-very favorable situation of uranium and thorium resources in Iran, the lack of extensive international cooperation, the existence of sanctions in the provision of raw materials for nuclear fuel production, and the impossibility of guaranteeing the supply of fuel needed for nuclear energy production, the need to pay more attention to establishing a closed fuel cycle and using fast breeder reactors is proven. Paying attention to this important issue will achieve goals such as reducing the need for natural uranium, reducing the cost of nuclear waste, improving the efficiency of nuclear power plants, and producing materials required for the use of radiation in industry, medicine, and health.
