WHAT IS GO-VIKING
It is only possible to avoid inevitable and irreversible climate changes if massive and immediate reductions in greenhouse gas emissions are made (IPCC, 2021). Nuclear safety is one of the ten priority actions to be performed to accelerate the energy system transformation and to reach future low-carbon energy system.
As nuclear power plants in Europe are ageing, extending their lifetime provides the necessary time for the transition to a low-carbon energy system. Flow-induced vibrations may cause failure in main nuclear steam supply system components such as fuel assemblies and steam generators. An in-depth understanding and prediction of FIV phenomena will assure the safe operation of the existing plants, especially those involved in long-term operation programs.
The GO-VIKING project aims to improve the safety of contemporary reactors and the design evaluation of new concepts, as well as to generate and disseminate knowledge on flow-induced vibrations among nowadays and upcoming stakeholders in the nuclear field.
HOW WE CONTRIBUTE TO NUCLEAR SAFETY
The increased knowledge on flow-induced vibration phenomena together with the state-of-the-art experimental program and the high-resolution numerical tools, that are enhanced and validated within the GO-VIKING project, are expected to contribute to the improvement of the design, operation, and safety of nuclear power plants, in particular through: Improved plant operation and availability, Enhanced plant safety and reduced exposure, Accurate and efficient tools and methods, Increased structural integrity of key plant components, Community building and networking between academia and industry.
TRAINING AND EDUCATION
The project will make new experimental results available as well as improved methods and numerical tools for the evaluation of flow-induced vibrations. The generated expertise within GO-VIKING will be synthesized in new industrial best-practice guidelines, most of them being also relevant for many non-nuclear industries. To reach a widespread application of the research results, GO-VIKING will develop educational material and trainings for young scientists, master and PhD students on Fluid-Structure Interaction related to nuclear applications, based on the contents provided by GO-VIKING experts. The design of the syllabus and course structures and the new scientific achievements in the field of nuclear engineering will also be adapted to young professionals in the nuclear field.
Educational and training content will be made available in the future, stay informed and subscribe to our newsletter!
