Nuclear Power Plants



According to regional, national and international regulations, Nuclear Power Plants (NPP) need to be able to mitigate potential effects of an earthquake. 

Such mitigation can be achieved by utilising specific instrumentation for monitoring the earthquake ground motions and the response of the plant features to these motions. 

This type of instrumentation is called Seismic Monitoring System (SMS). Main functions of the SMS are: 
  • Detection of any (significant) earthquake at plant location
  • Provide data records of acceleration at defined locations
  • Perform OBE/SSE exceedance evaluation
  • Provide a report to the plant operator after an event
  • Periodical self test execution
GeoSIG delivers complete SMSs for the NPP applications. These systems;
  • Comply fully or exceed regional, national and international nuclear regulatory requirements
  • Come with comprehensive certification and documentation, which can as well be supplied from
  • scratch for any particular requirement.
  • Include powerful industrial computer for complex data processing based on different algorithms including response spectra analysis
  • Perform automatic analysis and evaluation of the earthquake impact on monitored structures
  • Provide comprehensive and fast notification and reporting features
  • Warrant the robustness, reliability and functionality to serve it main purpose
  • Include self diagnostic and testing features to assure continuous system readiness to act once in a life
  • Present simplicity of operation, maintenance and upgrade 
Selected NPPs Instrumented with GeoSIG Instruments
In the past decades, GeoSIG Instruments have been delivered to more than 70 NPP's in more than 15 countries worldwide. Some of the NPP's around the world, which are instrumented with GeoSIG Instruments, are listed below.
