An innovative safety concept for a light water reactor has been developed at the KoreaAtomic Energy Research Institute. It is a unique concept that adopts both a fast heattransfer mechanism for a small containment and a changing mechanism of the coolinggeometry to take advantage of the potential, thermal, and dynamic energies of the coldwater in the containment. It can bring about rapid cooling of the containment and longtermcooling of the decay heat. By virtue of this innovative concept, nuclear fuel damageevents can be prevented. The ultimate heat transfer mechanism contributes to minimizationof the heat exchanger size and containment volume. A small containment canensure the underground construction, which can use river or seawater as an ultimate heatsink. The changing mechanism of the cooling geometry simplifies several safety systemsand unifies diverse functions. Simplicity of the present safety system does not require anyoperator actions during events or accidents. Therefore, the unique safety concept of PX canrealize both economic competitiveness and inherent safety.
