The SWR 1000 fuel pool coolers are tubular heat exchangers. They are installed on the fuel pool wall around the spent fuel storage racks. Fuel pool water is cooled by means of natural convection. Forced circulation flow of closed-cooling water exists on the tube side of each heat exchanger. The penetrations of the cooling water supply lines through the fuel pool liner are all located above the pool water surface. This ensures that the fuel pool cannot lose water in the event of a pipe break. Integration of the cooling components inside the fuel pool ensures only noncontaminated piping within the reactor building. The fuel pool cooling system consists of two redundant cooling trains. Each cooling train comprises four heat exchangers connected in parallel. The system must ensure adequate heat removal both during normal plant operation and in the event of any postulated accident. To verify proper functioning of the component, full-scale, steadystate tests were performed at the INKA (Integral Teststand Karlstein) test facility in Karlstein Germany. The characteristic diagram for heat transfer capacity of the component as a function of cooling water temperature and fuel pool water temperature obtained from these experiments will be presented in this paper.

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. [less ▲]
