ABSTRACT:
A nuclear reactor system having a water-cooled reactor includes a reactor containment. A shielding pit inside the reactor containment has a lower region with an outlet opening formed therein. A reactor pressure vessel is disposed in the shielding pit. A moderating cell is disposed downstream of the outlet opening and has a device for slowing down and diverting a melt flowing through the outlet opening. A catch basin is disposed downstream of the moderating cell for receiving a melt and a supply of water. A method for operating a nuclear reactor system includes covering the bottom of the catch basin with water during normal operation of the reactor, and maintaining the water in the catch basin at a surface level being lower than the lowermost region of the bottom of the shielding pit.
