Device for capturing core melt from reactor pressure vessel

摘要

In order to improve the outflow channel for melt-down products, the device has an antechamber (11) located below the pressure vessel (1) and an expansion chamber (19) for the melt-down products located to one side of the pressure vessel (1). The expansion chamber (19) is connected to the antechamber by a channel (17). A base unit (9) forms the floor of at least the antechamber (11) and is made of a material with a high thermal conductivity.
