Abstract

Application of Raman DTS to nuclear structure monitoring requires good knowledge of the metrological performance of this new technology. Periodical checks of the temperature readings will also be required on site, in zones that will no longer be accessible after installation. A novel, in-situ thermal cartridge was developed in order to calibrate and periodically check such measuring systems. This paper presents this innovative device and discusses the DTS-unit performance claimed by manufacturers.
