ABSTRACT:
A device for collecting core melt from a reactor pressure vessel improves a flow of the core melt out of the reactor pressure vessel. A prechamber is disposed below the reactor pressure vessel and a spreading chamber for the core melt is disposed laterally next to the reactor pressure vessel. The spreading chamber is connected to the prechamber through a channel. A base unit forms a bottom region at least of the prechamber and is made of a material having high thermal conductivity.
