Pebble Bed Modular Reactor

The Pebble Bed Modular Reactor (PBMR) is a type of nuclear reactor that uses thousands of small, spherical fuel particles called pebbles. These pebbles contain uranium fuel and are packed into a reactor core where they generate heat through nuclear fission. The design features continuous circulation of these pebbles, allowing for safer operation and easier fuel management. The reactor operates at high temperatures with a robust safety case, as its design minimizes the risk of accidents like overheating. PBMRs are considered efficient, scalable, and potentially safer sources of clean energy compared to traditional nuclear reactors.
