    The HYRICI project conducted during 2007 and 2008 was divided in two different research topics in the field of severe accident investigations: hydrogen distribution and the pressure and thermal loads caused by hydrogen combustion in the containment, and the coolability of ex-vessel particle beds formed after the discharge of molten corium into a deep water pool. Computational fluid dynamics codes were utilized in the hydrogen risk analysis. The evaluation of particle bed coolability consisted of both experimental and numerical studies. Experimentally, the effect of lateral bottom inflow into the particle bed was investigated in the STYX 10-13 test series. The project was connected to two international research programmes.
