Cavitation induced vibrations in orifice plates and a partially closed valve
Cavitation-induced vibrations in orifice plates and partially closed valves can lead to significant operational challenges and potential damage in the nuclear power plant. Cavitation can cause vibrations and erosion, compromising the integrity of critical components. Understanding and mitigating these effects is essential for maintaining safe and efficient operations.

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.
