Zirconium Oxide Thickness Measurement Using FTIR Zirconium Oxide Thickness Measurement Using Fourier Transform Infrared Spectroscopy (FTIR) Problem Statement Samples from nuclear stations can be significantly irradiated and therefore a source of dose for workers during post-service component examinations, especially when metallurgical operations are required. Increasingly, materials that have been irradiated in the core of CANDU nuclear reactors are being submitted to Kinectrics for analysis. In particular, analysis of oxide thickness of zirconium-based metals has been requested as a means of determining in-core residency times. A non-destructive solution that allows for oxide measurements with minimal worker dose has been developed and demonstrated. The Fourier Transform Infrared spectro
