This comprehensive publication presents the outcomes of an IAEA-coordinated research project (CRP) focused on the application of computational fluid dynamics (CFD) codes for nuclear power plant design. The primary objective of this project was to thoroughly benchmark CFD codes, model options, and methodologies against CFD experimental data under single-phase flow conditions. In summary, this publication provides an overview of the current capabilities and applications of CFD codes in the field of nuclear power plant design, along with their present qualification level in meeting the specific requirements of this industry. It serves as a valuable resource for international experts involved in nuclear power plant design, CFD applications, and related experimentation and validation. The guidance provided in this publication is based on extensive inputs from renowned nuclear industry experts who have direct experience in addressing nuclear power plant design issues, utilizing CFD tools, and conducting relevant experimentation and validation.

The CRP aimed to evaluate the performance and reliability of CFD codes in simulating complex flow phenomena within nuclear power plants. It involved a wide range of experimental studies conducted at various research facilities worldwide. The experimental data was used to validate the CFD models and to improve their accuracy and reliability.

One of the key findings of the CRP was that CFD codes have become increasingly capable of accurately simulating the flow behavior in nuclear power plants. This has enabled designers to optimize the design of components and systems, reducing costs and improving safety. CFD codes have also been used to study a wide range of phenomena, including coolant flow, heat transfer, and nuclear reactor dynamics.

The CRP also identified areas where further research and development are needed to improve the application of CFD codes in nuclear power plant design. For example, there is a need for more advanced CFD models that can accurately simulate the behavior of complex fluids and materials at high temperatures and pressures. Additionally, there is a need for improved simulation techniques and algorithms that can handle large and complex datasets efficiently.

In conclusion, this comprehensive publication highlights the significant advancements in the application of CFD codes in nuclear power plant design. It provides valuable insights into the current capabilities and applications of CFD codes, as well as their present qualification level in meeting the specific requirements of this industry. The guidance provided in this publication is based on extensive inputs from international nuclear industry experts and is intended to support the continued development and improvement of CFD tools in nuclear power plant design.
