Mark I Containment

Mark I Containment refers to the protective system used in certain nuclear reactors to contain and control radioactive materials. It is a reinforced structure surrounding the reactor core designed to contain any potential release of radioactive gases or materials during an accident. This containment acts as a barrier, preventing radioactive substances from escaping into the environment, thereby protecting public health and safety. The Mark I design uses thick steel and concrete to withstand high pressures and prevent leaks, ensuring that even in unlikely failure scenarios, radioactive release remains limited.
