Thorium reactors are a type of nuclear reactor that use thorium as a fuel source instead of the more common uranium. Thorium is more abundant and produces less long-lived radioactive waste. In these reactors, thorium-232 absorbs neutrons and transforms into uranium-233, which can then be used to generate energy. One of the key advantages of thorium reactors is their potential for enhanced safety. They operate at lower pressures and temperatures compared to traditional reactors, reducing the risk of catastrophic failures. Additionally, thorium reactors can be designed to be more efficient, potentially leading to a more sustainable energy future.
