Torsional Vibrations in Steam Turbine Shaft Trains
A collection of practical experiences related to torsional vibrations in shaft trains is given. It also presents different kinds of measurement methods and deals with potential measurement & monitoring systems.
Furthermore, an overview on mitigation measures, which are divided in procedures and commercial systems, is given. Finally, a guide for conceptually detecting and solving torsional vibration problems is provided.

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.
