Core Catcher Cooling Structures

Safety barrier for the reactor

Siempelkamp supplies the cooling structures of the core catcher for the EPR™ reactor, a generation III+ reactor type with a block output of around 1,600 MWe. Construction projects are currently being realized or have already been completed in the United Kingdom as well as in Finland, France and China.

The core catcher supplements the primary safety systems of the EPR™ reactor, whose task is the reliable prevention, avoidance and management of nuclear wastes. In the event that all of these systems fail completely and there is a meltdown of the reactor's core, the core catcher is used to catch and permanently cool the molten material before it can reach the foundation. Thus, the containment is maintained as the ultimate safety barrier. The core catcher is a complex structure made up of a large number of individual cooling elements consisting of ductile cast iron and a steel structure.

For this safety component, too, Siempelkamp supplies the whole package: cast iron elements, steel structure and assembly by the experienced Siempelkamp service team.
