Nuclear power plant cables are classified into CLASS 1E cables used in electrical equipment and systems and NON-CLASS 1E cables used in Non-Nuclear Safety systems in reactors and control rooms. They are used inside power plant buildings in the event of a nuclear reactor accident to prevent radiation leak into the surrounding environment by tripping nuclear reactors and isolating, cooling, and removing heat from the containment vessel.
