Progress report on research and development activities in 1982 of the Institut fuer Reaktorentwicklung

The contributions to the Fast Breeder Project comprise theoretical and experimental investigations on the dynamic behaviour of fast breeder reactors during operation and hypothetic incidents, investigations of effects of local cooling failures in the reactor core in consideration of possible failure propagation mechanisms, the detection of such processes as well as the performance of risk-oriented analyses. The work on the Project Nuclear Safety of Lightwater Rectors involves analyses of the reactor pressure vessel and of the containment structures under incident conditions, work on the behaviour of fuel rods during a loss-of-coolant incident as well as investigations of two-phase flows. Regarding the new main subject of investigations in the Nuclear Fusion Project the IRE will at first contribute in the fields of design and analysis of highly loaded components. (orig./GL)
