Hydrogen posses a major threat to containment integrity in the case of a severe accident in a nuclear power plant. Reliable analysis of severe accident situations and optimisation of mitigation designs are essential for enhancing safety and avoiding unnecessary conservatism. To ensure this, the analytical tools being developed by many organisations world-wide must be validated on an experimental data base which covers relevant aspects of the hydrogen problem: sources, distribution, deflagration, detonation. The experimental and analytical work performed in this project contributes to the data base in the fields of slow to fast deflagration. It addresses especially the aspects of hydrogen combustion in complex, multi-compartment configurations on large, plant typical scale and with premixed, inhomogeneous gas mixtures. Advanced models, deflagration criteria and numerical tools developed by the partners will be validated against experiments which will result in qualified tools with well defined ranges of applicability for hydrogen risk assessment of nuclear power plants.
