An experiment on hydrogen combustion was performed on March 12, 2012 at the Karlsruhe Institute of Technology (Germany). In the HYKA A2 cylindrical vessel, with a volume of 220 m3, a homogeneous mixture of air (68 vol.%), steam (20 vol.%) and hydrogen (12 vol.%) was established at pressure 1.5 bar and temperature 92 ºC. The mixture was ignited at the bottom of the vessel in the centre, so that the flame propagated vertically upwards and horizontally in the outer direction. The maximum pressure was 5 bar and the maximum temperature 1018 ºC.

The Elsevier publishing company has published the book Nuclear Safety in Light Water Reactors under the editorship of Prof. Bal Raj Sehgal from the Royal Institute of Technology in Stockholm (Sweden). The book is the first one, in which all phenomena that occur during a severe accident in a nuclear power plant are considered. The project researcher I.Kljenak has contributed, together with two colleagues from IRSN (France) and KIT (Germany), the chapter about hydrogen behavior and control.

Within the Severe Accident Network of Excellence (SARNET2, 2009-2013), we have participated in benchmark exercises, which were organized using experiments on hydrogen deflagration that were performed in the ENACCEF experimental facility, located at the Centre National de la Recherche Scientifique in Orleans (France). The project group has simulated experiments with the lumped-parameter code CONTAIN.

THAI is a cylindrical experimental vessel, with a volume of 60 m3, located at Becker Technologies (Germany). Within the OECD THAI project, 29 experiments on hydrogen combustion were performed in the vessel (among them the test HD-22 that was performed at similar conditions as the UFPE experiment within the project). Within the 7th Framework Programme of the European Commission, 9 (nine) experiments on hydrogen combustion, performed at different pressures and temperatures, and with different compositions of the homogeneous atmosphere (the hydrogen and steam concentrations were varied) were simulated with the ASTEC lumped-parameter code.

A benchmark exercise for lumped-parameter codes was organized with the experiment on hydrogen combustion, proposed by the Jozef Stefan Institute and performed at the Karlsruhe Institute of Technology (Germany). Apart from the organiser (JSI), the following organisations also participated in the exercise: NUBIKI (Hungary), UJD SR (Slovakia), RSE (Italy), LEI (Lithuania) and AEP (Russian Federation). The following codes were used for the simulation of the experiment: ASTEC, COCOSYS, ECART and ANGAR. The benchmark confirmed the adequacy of the codes for simulation of hydrogen combustion in large volumes.
