A Liquid Fluoride Thorium Reactor (LFTR) is a type of nuclear reactor that uses thorium as fuel instead of the more common uranium. In this design, thorium is converted into uranium-233 through a process called breeding. The reactor uses a liquid fluoride salt as both the coolant and the fuel, allowing for efficient heat transfer and improved safety. LFTRs operate at higher temperatures than traditional reactors, which can lead to greater efficiency in electricity generation. Additionally, they produce less long-lived radioactive waste and have a lower risk of nuclear proliferation, making them a promising alternative for sustainable energy production.
