Background

The development of innovative reactor systems requires accurate predictions of thermal-hydraulics phenomena involved. Given the characteristics of fluids employed, the very specific thermal and fluid dynamic conditions and strict safety regulations, purposely developed physical models and Computational Fluid Dynamics techniques are needed. While different research programs within this scope came to important conclusions and provided new reliable tools for the design of innovative reactors, a number of thermal-hydraulics issues are still to be clarified.

Successful research in this field requires the performance of experiments and the use of experimental results do develop new physical models and computational methods. Moreover, experimental results and models developed must be disseminated between researchers. Information exchange should address the many common thermal-hydraulic issues that can be identified which are of central importance in different innovative reactor systems. These are of course core design and coupled kinetics/thermal-hydraulic simulations but also more fundamental subjects such as the development of advanced experimental techniques and reliable numerical models for multiphase flow and turbulent convection in liquid metals and supercritical water.

This workshop is intended to provide the research community with an opportunity to exchange ideas, discuss results from both experimental and numerical investigations, assess development of computational fluid dynamics codes for advanced reactor systems and to clarify advanced reactor thermal-hydraulics issues. Further, the workshop will be an occasion for exchange information about research programs in order to establish future collaboration and to plan new research projects both in a European framework and worldwide.
