Description

During a severe accident, hydrogen and steam are produced due to intensive temperature rise of the core. The hydrogen produced in the core can readily diffuse to various zones of the containment. If the hydrogen concentration reaches a prescribed threshold value at a specific location, it can result in deflagration and even detonation. A large temperature and pressure spike may occur to challenge the relevant safety system of the containment. In worst case scenario, safety system of the containment can be breached.
