The GO-VIKING consortium met on 20–21 November 2025 at Ghent University (UGent) for a two-day Progress Meeting to assess scientific developments and coordinate the next stages of the project. Hosted in Ghent (Belgium), the meeting brought together experts from across Europe to discuss advances in modelling, experiments, and the understanding of flow-induced vibrations (FIV) in nuclear systems.
Day 1 – Project updates and technical developments
The meeting opened with welcome remarks from A. Papukchiev (GRS) and K. Zwijsen (NRG PALLAS), followed by organisational matters introduced by J. Degroote (UGent). The GO-VIKING Project Office, represented by R. Canu (LGI) and G. Niedermeyer (GRS), then provided an overview of ongoing coordination and reporting activities.
Updates continued with progress in education, training, and dissemination from VKI, ENEN and LGI, before moving into the project’s core technical work. Partners from GRS, IPP, NRG PALLAS, UGent, and TUD presented advances in fast-running methods, uncertainty quantification, synthetic turbulence modelling, model order reduction for AMOVI, applications of AniPFM, and calibration approaches for the Cantilevered Rod case.
After the lunch break, discussions shifted toward fuel assemblies and steam generators, with contributions from Framatome, IPP, NRG PALLAS and EDF. Significant attention was dedicated to the GOKSTAD and AMOVI campaigns, with updates from VKI, EDF, NRG PALLAS, VCU and IPP on high- and medium-resolution simulations.
Day 2 – Multiphase flow focus
The second day concentrated on FIV in multiphase flows, led by EDF. Partners from ASNR and NRG PALLAS presented joint updates on modelling strategies and simulation progress, as well as the experimental developments into ongoing work in the TREFLE and TITAN experiments.
The meeting concluded with a dedicated Project Management Board session evaluating the current status of the consortiums progress and the next steps to take in the final 6 months of the project
Moving forward
The Ghent Progress Meeting demonstrated the strong collaboration across the consortium and the steady progress being made across all technical areas. With significant advances in high-fidelity simulations, experimental data generation, and methodological development, GO-VIKING will continue to work towards providing reliable tools and best practices for analysing flow-induced vibrations in nuclear systems.
