Feature Extraction & Identification Techniques for the Alignment of Perturbation Simulations with Power Plant Measurements

  • 1. Institute of Communication and Computer Systems National Technical University of Athens
  • 2. Chalmers University of Technology


•We propose a methodology for the comparison of measured and simulated neutron noise signals in nuclear power plants
•The key components of the proposed methodology are:
1.Auto-Power Spectral Density ofplant measurements in order to identify possible perturbation frequencies
2.Cross-Power Spectral Density between plant measurements and simulated data in order to identify possible perturbations
•Reactor core used in this study is a German 4-loop pre-KONVOI Pressurized Water Reactor
