Survey of Vibration Dampers

Updated 2025-02-13 Published 2020-09-24

Knowledge and practical experience on vibration dampers at the Nordic nuclear power plants has been collected here.

The main focus is vibration dampers suitable for piping applications, where both transient and steady state vibration are common problems that may be mitigated using vibration dampers.

Comparison of different types of dampers and their functions and capabilities including their advantages and disadvantages are highlighted, but also design and maintenance issues using vibration dampers to follow the special requirements at the nuclear power plants are described.

New method for investigating concrete structures in nuclear power plants

Nuclear power, which accounts for about 30% of Sweden's electricity production, plays a crucial role in delivering fossil-free electricity. As many nuclear power plants are approaching the end of their planned lifetime, it is crucial to extend their operating periods to meet current and future needs. Markus Nilsson at Lund University has spent four years investigating how non-linear ultrasonic methods can be used to detect and assess corrosion in concrete-embedded containment liners in nuclear power plants. The work has resulted in a doctoral thesis.

"Lifetime extension of nuclear power needs more focus"

The Life After 60 – Long Term Operation of Nuclear Power conference, hosted by Energiforsk last week, was fully booked. The importance of lifetime extension, the need for competence, and why green politicians acknowledge the necessity of nuclear power were three key topics that resonated throughout the event.
