The European Seismic Hazard Model 2020 (ESHM20) succeeds the 2013 model (ESHM13) using the same approach of state-of-the art procedures homogeneously applied to the entire pan-European region, without country-border issues. The models are not intended as sitespecific hazard models, they are not applicable to annual probabilities of exceedance below 2·10-4 and do not replace national hazard models. For Fennoscandia, the update only increases the earthquake data set by eight events, but the seismic source zones were updated, there was a complete change of ground motions models and the logic tree was significantly expanded.

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.
Exploring vibrations in power plants with Professor Rainer Nordmann
Energiforsk and Professor Rainer Nordmann have arranged a one-day-lecture tour of Sweden and Finland on turbogenerator vibrations.
Pump course in the Netherlands strengthened the Nordic nuclear power competence
– I appreciate that we were given the opportunity via Energiforsk to design a course that suited our purposes and hope more colleagues will have the opportunity to take it, says Lena Skoglund.
