What is the function of containment building?

A containment building is designed to encase nuclear reactors and other hazardous materials to prevent the release of radioactive substances into the environment. It provides a robust structure that can withstand extreme events, such as earthquakes or explosions, ensuring the safety of both the public and the environment. The building typically features reinforced concrete and multiple barriers to contain any potential leaks or emissions. Overall, its primary function is to maintain safety and security in nuclear operations.
