Optical pyrometry measurement on oxidized zirconium alloy nuclear material cladding
Abstract
International audience ; In order to improve the safety of nuclear power plant, loss-of-coolant accident experiments areimplemented in research reactor. In this framework, we develop an optical pyrometry device to measuresurface temperature (700-1200°C) of Zircaloy cladding without contact. The whole set-up of thesimplified device (under air, without radiation) and the measurement procedure including data treatmentbased on bichromatic pyrometry are presented, as well as results for various temperature levels.Temperature retrieval based on the hypothesis of emissivity ratio equal to a constant, is scanned over alarge wavelength range. A constant surface temperature is obtained on the spectral range ofmeasurement, confirming the relevancy of emissivity hypothesis. Differences between this non-contacttemperature measurement and a complementary thermocouple temperature measurement are alsodiscussed.
