NSUF 25-5468: X-ray diffraction and eddy current study of irradiation growth in zirconium alloys

We propose to perform Frequency Scanning Eddy Current Eddy Current and transmission synchrotron X-ray Diffraction measurements on the same set of pre-irradiated zirconium alloy specimens. Specimens will be measured for electrical conductivity using the eddy current technique and XRD patterns will be analyzed for irradiation-induced microstructure changes that result in irradiation growth. Results from the two types of measurements will be compared to determine functional relationships between electrical conductivity and irradiation growth microstructural and macroscopic parameters; if successful, this technology will enable poolside characterization of the factors contributing to irradiation growth. We expect this work to be completed within 11 months from the award date. Research results will be published in the open literature.
