The ISP-47 programme was carried out in two steps: Step 1 was dedicated to code validation using test data from the separate effects facility TOSQAN (7 m3 volume) and the larger-scale MISTRA facility (100 m3 volume). In the TOSQAN tests, wall condensation, steam injection in air or air/helium atmospheres, and buoyancy were addressed under well-controlled initial conditions in a simple geometry. The interactions of phenomena such as condensation/stratification and turbulence/buoyancy were addressed in the MISTRA tests. Both TOSQAN and MISTRA were specifically designed to produce data for CFD codes with state-of-the-art instrumentation. The TOSQAN benchmark was open, whereas the MISTRA benchmark was blind. Step 2 was devoted to code validation using an experiment in the multi-compartment ThAI facility (60 m3 volume) with different steam and helium injection phases, transient stratification and mixing conditions in the atmosphere, development of natural convection, wall condensate distribution, fog formation, and transient thermal response of heat-conducting walls. From this experiment, detailed measurement data on velocity, temperature and gas concentration fields are provided for detailed code validation. The ThAI benchmark covered three sets of calculations: completely blind, partly blind and open.
