Advanced nuclear fuel refers to innovative materials designed to enhance the efficiency and safety of nuclear reactors. These fuels can include a variety of compositions, such as uranium, plutonium, or thorium, often combined with other elements to improve performance. The goal is to produce more energy while generating less waste and reducing the risk of accidents. One significant type of advanced nuclear fuel is MOX (mixed oxide fuel), which blends plutonium with uranium dioxide. This fuel allows for the recycling of nuclear waste and can be used in existing reactors, contributing to a more sustainable nuclear energy cycle. Advanced fuels are crucial for the future of nuclear power, aiming to meet growing energy demands responsibly.
