Abstract EN
Temperature and strain monitoring will be implemented in the envisioned French geological repository for high- and intermediate-level long-lived nuclear wastes.
Raman and Brillouin scatterings in optical fibers are efficient industrial methods to provide distributed temperature and strain measurements.
Gamma radiation and hydrogen release from nuclear wastes can however affect the measurements.
An industrial qualification process is successfully proposed and implemented.
Induced measurement uncertainties and their physical origins are quantified.
The optical fiber composition influence is assessed.
Based on radiation-hard fibers and carbon-primary coatings, we showed that the proposed system can provide accurate temperature and strain measurements up to 0.5 MGy and 100% hydrogen concentration in the atmosphere, over 200 m distance range.
The selected system was successfully implemented in the Andra underground laboratory, in one-to-one scale mockup of future cells, into concrete liners.
We demonstrated the efficiency of simultaneous Raman and Brillouin scattering measurements to provide both strain and temperature distributed measurements.
We showed that 1.3 μm working wavelength is in favor of hazardous environment monitoring.
