ABSTRACT:
The emergency core cooling structure according to the present invention is provided with a water storage container which holds therein emergency cooling water to be supplied to a core region in a nuclear reactor in case of an emergency, for example, when the primary cooling water flows out from a reactor vessel, so as to maintain the temperature of the emergency cooling water in the upper portion of the water storage container in a level higher than the level of that of the emergency cooling water in the lower portion thereof, the lower portion of the water storage container, which is filled with the low-temperature cooling water, being communicated at all times with the core of the nuclear reactor by a means which has substantially no movable member. When the primary cooling water flows out, so that the pressure in a reactor vessel decreases, the emergency cooling water in the high-temperature region is boiled to expand to cause the low-temperature emergency cooling water in the lower portion of the water storage container to be raised, the resultant low-temperature emergency cooling water being supplied to the core region.
