The experimental program included single component/system tests of the Emergency Condenser, the Containment Cooling Condenser and the Passive Core Flooding System. Integral system tests, including also the Passive Pressure Pulse Transmitter, will be performed to simulate transients and Loss of Coolant Accident scenarios at the test facility. The INKA test facility represents the KERENA Containment with a volume scaling of 1£¿:£¿24. Component heights and levels are in full scale. The reactor pressure vessel is simulated by the accumulator vessel of the large valve test facility of Karlstein¡ªa vessel with a design pressure of 11£¿MPa and a storage capacity of 125£¿m3. The vessel is fed by a benson boiler with a maximum power supply of 22£¿MW. The INKA multi compartment pressure suppression Containment meets the requirements of modern and existing BWR designs. As a result of the large power supply at the facility, INKA is capable of simulating various accident scenarios, including a full train of passive systems, starting with the initiating event¡ªfor example pipe rupture. 1. Introduction The KERENA is a medium-capacity boiling water reactor (BWR). It combines passive safety systems with active safety equipment of service-proven design. The passive systems utilize basic laws of physics, such as gravity and natural convection, enabling them to function without electric power or actuation by electric instrumentation and control (I&C) equipmentThey are designed to bring the plant to a safe and stable condition without the aid of active systems. Furthermore, the passive safety features reduce the number of active systems, significantly reducing costs, while providing a safe, reliable, and economically competitive plant design [1, 2]. The Integral Test Facility Karlstein (INKA) test facility was designed and erected to experimentally analyze the passive safety systems of KERENA. Therefore, all passive safety features necessary to simulated accident scenarios (loss of coolant accident [LOCA] and non-LOCA) are included in the design. The following section gives a brief description of these passive systems. The INKA setup simulates the KERENA Containment in a 1£¿:£¿24 scale. Component size and levels are full scale in order to match the driving forces for natural circulation in systems.
