Thermal hydraulics is recognised as key to the development of next-generation reactor systems. EU-funded researchers have developed new physical models and improved numerical analysis tools as well as their application to address cross-cutting issues.
The nuclear reactor design has gone through four generations. Compared to the second generation (Gen II), Gen III ensures a higher safety level. However, Gen III nuclear reactors do not meet the requirements of a longer-term nuclear power development.
