This was the annual seminar of the Energiforsk research programme Vibrations in Nuclear Applications. The seminar was a hybrid event offering both virtual participation and physical participation at Fortums office in Espoo, on the 6th of November.
Results from recent research projects on vibrations in nuclear applications was presented during the seminar by both organisations and researchers.
The purpose of Energiforsk's Vibrations R&D programme is to increase the knowledge within the nuclear field on how to best manage issues related to vibrations. This recurring seminar is one of the ways in which we contribute to increasing the knowledge of measurement, analysis, and mitigation of vibrations in key components in the nuclear power plant.
