Vibrations in Nuclear Applications

The Vibrations in Nuclear Power programme produce and provide knowledge on operational problems related to vibrations. This knowledge is valuable in maintaining safe, efficient operation and in decision processes for investments.

Reports

Vibrations in components in a Nuclear power plant can result in production distribution and loss of income from the facility. However, there is lacking knowledge within this field amongst manufacturers and consultancies on how to best manage these issues. The research in this programme is foremost dedicated to providing research and knowledge on the most recent developments and equipment testing for piping, generators, and turbines.

The programme's main focus areas are:

Digitalised vibration management
Technical challenges
Implementation and knowledge transfer

Karin Westling

Research Area Director Nuclear Power and Programme Manager Hydropower

I’m the Head of Nuclear Research and oversee six of our programs: Concrete, Outlook & Technology, ENSRIC (I&C), Vibrations, Gino (interaction between nuclear power and the grid), and Polymeric Materials. I also serve as the program council lead for the Swedish Centre for Sustainable Hydropower (SVC). Throughout my career as a project manager, I’ve moved between the construction and energy sectors, focusing on hydropower, nuclear power, and public buildings for culture and sports. It’s important to me that my work contributes to society and benefits others. I’ve lived in Stockholm for many years, but I’ll always be a Dalsland native at heart.

Grid-induced mechanical stress on the turbine-generator shaft
Grid disturbances increasingly challenge the mechanical integrity of nuclear power plant turbines, as the Nordic power system evolves with more renewables and power electronics. This study aims to identify which grid events most affect turbine-generator mechanical integrity, evaluate risk factors and assess monitoring and protection solutions.

Cavitation induced vibrations in valves
Cavitation and flow-induced vibrations in valves are critical issues in piping systems, particularly in nuclear power plants, where reliability and structural integrity are essential. These phenomena can lead to fatigue damage, erosion, and reduced operational safety.
