Gathering expertise On Vibration ImpaKt In Nuclear power Generation

Project description

Advanced modelling of flow-induced vibrations to improve nuclear power plant operation and safety

Nuclear power plants use water to cool the reactor core and generate steam, necessary for the turbine driving the generators for electricity production. The water flow interacts with the structures (fuel rods, steam generator tubes), which may start to vibrate. Flow-induced vibrations (FIV) in nuclear plants can lead to material wear and even breach of the radioactive confinement. Therefore, the prediction and analysis of such phenomena is of great importance. The EU-funded GO-VIKING project will improve the understanding of FIV in nuclear fuel assemblies and steam generators. The team will generate new experimental and high-resolution numerical data, develop methods and synthesise guidelines to improve the prediction and analysis of FIV in nuclear reactors. Project outcomes will help enhance the operation, safety and reliability of nuclear power plants.

Objective

The Gathering expertise On Vibration ImpaKt In Nuclear power Generation (GO-VIKING) project takes over from the VIKING initiative that started in 2020 as an in-kind collaborative effort of European vendors, utilities, technical safety organizations, universities, and research organizations to improve the understanding and the prediction of flow-induced vibration (FIV) phenomena, relevant to nuclear power reactors. Preventive measures against FIV should be taken in the component design and during the operation of the nuclear steam supply system (NSSS) to avoid structural wear, damage or even incidental or accidental scenarios with potential radioactivity release to the environment. The overall objective of GO-VIKING is to increase the expertise and improve the tools and skills of the European nuclear stakeholders for the analysis of complex FIV phenomena in order to maintain and enhance nuclear plant safety. This will be accomplished by:
- Generation of high-resolution numerical and experimental data of FIV in single and multiphase flows.
- Development and validation of high- and medium-resolution, as well as fast-running practical tools for the FIV analysis
- Implementation of efficient methods for uncertainty propagation in the FIV results
- Synthesis of best practice guidelines for FIV analysis in accordance with the needs of the stakeholders
- Targeted training of graduates and young experts as well as practitioners from stakeholders in FIV-related phenomena and modelling techniques
The GO-VIKING project will improve the safety of contemporary reactors and the design evaluation of new concepts by making available new experimental results and improved numerical approaches for the evaluation of FIV. These will allow the nuclear operators to enhance the prediction of FIV phenomena in key NSSS components, and the vendors to improve the design of the relevant equipment, thus leading to increased reliability, availability, and safety of the European NPPs.
