The aim of this report is to review the current understanding and research on hydrogen in LWRs. The main reactions through which hydrogen is produced are assessed, together with their timings. An estimate of the amount of hydrogen produced by each reaction is given, in order to assess their relative contribution to the hazard. An overview is then given of the state of knowledge of the most important phenomena taking place during its transport from the place of production, the phenomena which control hydrogen combustion, and the consequences of combustion under various conditions. Specific research work is recommended in each sector presented. The last topics reviewed are hydrogen detection and the prevention/mitigation of pressure and temperature loads on containment structures and safety related equipment caused by hydrogen combustion.
