A pebble bed reactor is a type of nuclear reactor that uses small spherical fuel elements, or "pebbles," to generate heat through nuclear fission. These pebbles are made of a mixture of uranium and graphite, and they are designed to withstand high temperatures and prevent the release of radioactive materials even in the event of a meltdown. The pebbles are continuously cycled through the reactor core, allowing for efficient heat transfer and reducing the risk of overheating. Pebble bed reactors are known for their inherent safety features and potential for high thermal efficiency. **
