Abstract
The activities on the validation of the ECART code against the eight Ingress of Coolant Event (ICE) tests performed in the upgraded ICE facility are discussed. These analyses have been carried out to extend the ECART validation to incidental sequences related to future fusion plants, specifically - in the case of ICE - versus Loss Of Coolant Accident (LOCA) in volumes with near vacuum conditions. The upgraded ICE facility consists of a boiler, injecting water at high pressure inside a low-pressure tank simulating the Plasma Chamber (PC). This PC is in turn connected to the Vacuum Vessel (VV) through the divertor, and to the pressure Suppression (ST) by means of several relief pipes. Finally, the VV is connected with the Drain Tank (DT). Eight tests were performed investigating different numbers of relief pipes, different initial PC and VV temperatures, and different injected water mass flow rates, pressures and temperatures. The ECART results show an overall good agreement with the experimental data, confirming that ECART is also a valuable tool for the safety analysis in future fusion plants, as already pointed out in previous works.
