Key Points

  • This research aims to develop an optical method for monitoring reactor power using Cherenkov emission.
  • Commercial camera records Cherenkov light for monitoring reactor power.
  • Video data is synchronized with reactor console data and calibrated to correct sensor saturation at high power levels.
  • Optical monitoring provides a complementary signal for spatial integration.
  • Cherenkov-derived estimates significantly reduce high-power noise compared to traditional detectors.
  • The nonlinear calibration effectively addresses sensor saturation issues.
  • Optical monitoring allows for integrated spatial data collection.

Abstract

• A commercial camera records Cherenkov light for reactor power monitoring. • Video-derived blue intensity is synchronized with reactor console data. • Nonlinear calibration corrects sensor saturation at high reactor power. • Cherenkov-derived estimates reduce high-power noise versus detectors. • Optical monitoring provides a spatially integrated complementary signal.
