SWR 1000 integral and full scale tests of the passive safety systems

The SWR 1000 is an innovative boiling water reactor concept with passive safety systems. In order to verify the functionality of the passive components required for the transient and accident management, the test facility INKA (Integral-Versuchstand Karlstein) is build up in Karlstein (Germany). The INKA test facility is designed to test the full scaled Emergency and Containment Cooling Condenser under steady state conditions as well as to simulate different postulated SWR 1000 transients and Loss of Coolant Accidents in a down scaled setup. The goal of the experiments is to obtain the power characteristics of the components and to demonstrate the ability of the passive safety systems to transfer the plant into a safe and stable state in case of a transient or LOCA. In this paper the INKA test facility setup including the tested components and the vessels, simulating the SWR 1000 containment will be described.
