Computer simulation of incident scenarios

Multi-phase flows play an important role in reactor safety research, e.g. for predicting the behavior of complex water-steam mixture flows in incident scenarios.
The theoretical models for the fundamental phenomena involved are validated at the TOPFLOW facility of the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), where flows at pressures and temperatures similar to those in a nuclear reactor can be studied by means of innovative imaging measurement technology.
For example, to describe a postulated loss-of-coolant accident and assess the effectiveness of safety systems, high-resolution CFD codes are used. The models developed for this are examined in single-effect tests and large-scale experiments, some of which are conducted in Germany.
