Pressurized-water reactor emergency core cooling system

Patent ·
OSTI ID:7209790
A pressurized-water reactor emergency core cooling system, in the event of a loss-of-coolant accident, has means for introducing at least one-quarter of the emergency cooling water supply directly into the open space formed between and around the control rod guide tubes of the reactor's upper guide and support structure above the reactor's core and within the pressure vessel. The water introduced is under pressure and is done in such a way as to form a wide-area spray screen filling the open space with the sprayed water as completely as possible.
