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

Rådsansvarig Kärnkraft

Jag ansvarar för forskningsområde Kärnkraft och sex av de ingående programmen: Betong, Outlook & technology, ENSRIC (I&C), Vibrationer, Gino (interaktion mellan kärnkraft och nät) och Polymera material. Utöver det är jag programrådsansvarig för Svenskt centrum för hållbar vattenkraft, SVC. Under mitt arbetsliv som projektledare har jag hoppat hage mellan bygg- och energibranscherna med fokus på vattenkraft, kärnkraft och offentliga kultur- och idrottsfastigheter. Det är viktigt för mig att mitt arbete ger något tillbaka till samhället och övriga medborgare. Jag har bott i Stockholm länge, men är och förblir dalslänning.

Cavitation induced vibrations in orifice plates and a partially closed valve
This study aims to experimentally investigate flow-induced vibrations and cavitation in single-hole and multi-hole orifices and a partially closed Stafsjö valve. The goal is to provide experimental data for validating Computational Fluid Dynamics (CFD) models.
