Nordic earthquake experts convene in Espoo
Since
the Fukushima accident, Nordic nuclear power plant areas have given
greater priority to understanding the safety implications of seismic
events. VTT and various Nordic players are co-developing new methods of
making seismic hazard estimates of anticipated earthquakes in
Fennoscandia.
Little
source modelling-based measurement data is available on earthquakes in
stable continental areas. On 8 May 2015, VTT Technical Research Centre
of Finland Ltd will organise a workshop aimed at identifying and sharing
the relevant Nordic data.
An
upcoming four-year project will also involve updating existing
earthquake source modelling techniques and developing new ground motion
simulation models for stable continental regions, particularly the
Fennoscandian Shield.
A thorough empirical analysis has been conducted. However, a lack of empirical observations of ground motion close to actual, high-magnitude earthquakes in Fennoscandia has impeded our understanding of the seismic load caused by a potential earthquake close to a nuclear power plant. Recent developments in calculation methods are enabling the formation of calculation models that generate realistic estimates of earthquake loads.
The project’s network of experts will focus on areas at low risk of seismic activity in the Nordic countries and further strengthen cooperation between VTT and Uppsala University in seismic source modelling.
In this project, the partners of VTT will be Aalto University, the University of Helsinki, Uppsala University, GEUS Geological Survey of Denmark and the Nordic leader in technical consulting, ÅF. The project will be funded by NKS Nordic Nuclear Safety Research.
The project’s long-term goal will be to expand cooperation of this kind to cover the Baltic countries.

The
project results will not only provide the background information
required for the safety assessment of nuclear power plants, but will
also be important with regard to final disposal repositories for nuclear
waste. In addition, the results will be useful for the National Nuclear
Power Plant Safety Research (SAFIR2018) programme’s NEST project.
The “Potential of numerical methods to supplement empirical earthquake observations” workshop will be held on 8 May 10 a.m. – 1 p.m. in Espoo, at the address Tekniikantie 1, Otaniemi.
