Containment structure

Definition

A containment structure is a vital component of a nuclear reactor designed to confine radioactive materials in the event of an accident or leak. This robust structure typically consists of reinforced concrete and steel, ensuring that any potential release of radiation is minimized and contained within the reactor facility. The effectiveness of a containment structure is crucial for the overall safety of nuclear operations and impacts waste management strategies.
