Fast Reactor

A fast reactor is a type of nuclear reactor that uses high-energy, fast-moving neutrons to sustain the nuclear fission process. Unlike traditional reactors that use slow neutrons and rely on materials like water for cooling and moderation, fast reactors use a coolant such as liquid metal (e.g., sodium) to transfer heat without slowing the neutrons. This allows them to efficiently utilize a wider range of nuclear fuels, including waste from other reactors, reducing nuclear waste and potentially producing more fuel. Fast reactors are considered promising for advanced nuclear energy due to their fuel efficiency and waste management advantages.
