Survey of pump and pump unit vibration
This project aims to collect the knowledge and experience of vibrations in pump and pump unit systems. The information is assembled in this report and can be used to increase awareness of which pump vibration problems that may arise and how to best avoid them when working with maintenance and quality assurance both during the commissioning phase of new equipment, as well as in a long-term operational perspective. The report is based on interviews with three Swedish and two Finnish nuclear power plants.

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.
