Seidelberger, E

In a nuclear reactor, a line for supplying emergency coolant is connected directly to the reactor pressure vessel and equipped in the interior of the latter with an emergency coolant flow-directing device whose exit runs parallel to the wall of the pressure vessel in a direction toward the lower edge of the core. The invention provides, particularly in pressurized-water reactors, more rapid flooding of the reactor core in case of a loss-of-coolant accident. 3 claims, 3 figures.
