Pipe Vibrations in Nuclear Power Plants

Vibration problems cause significant production and economic losses in nuclear power plants (NPP). In the end of 2009, high-pressure turbine valves of Forsmark 2 were mod-ified in order to increase the power output of the plant. The modified valves caused severe vibrations and roughly half of the planned energy production in 2010 was lost due to
