After irradia- tion, the samples were characterized using XAFS technique at the MRCAT beamline at APS. Since the ion-irradi- ation damage zone is only a few μm from the surface, the samples were tilted to three different angles (90°C, 45°C, and 25°C) to the X‑ray beam to study radiation damage at different depths.The experimental procedure is summarized in Figure 1. A typical K-edge absorption spectra for an irra- diated zircaloy specimen (25°C to the X-ray) is shown in Figure 2. Further data analysis and interpretation of the X-ray Absorption Fine Structure data are needed.This research was conducted primarily by Kun Mo and Jeff Terry, and facilitated in large part by staff in the Nuclear Engineering Division at ANL and Illinois Institute of Technology, includingYinbkin Miao (ANL), Sumit Bhattacharya (ANL), Laura M. Jamison (ANL), Bei Ye (ANL),Walid Mohamed (ANL), DiYun (ANL), Abdellatif  M. Yacout (ANL), Daniel Velázquez (IIT), and Rachel Seibert (IIT). Future Activities The experiment is completed. Data processing and results analysis will be finished in FY 2016.
