Neutron radiography (nR) and neutron computed tomography (nCT) are useful techniques for imaging hydrogen in metals. We have performed quantitative nR to characterize hydride rim structures on Zircaloy cladding [nR H in Zircaloy], for example. The videos below show hydrogen lens or blisters on Zircaloy cladding (first two videos) and a “city scape” of Zircaloy tubing and bars with hydrogen. The videos are 3-D reconstructions of nCT measurements performed at the High Flux Isotope Reactor at ORNL using IMAGING. This work was done in collaboration with Dr. Hassina Bilheux and Dr. Jean-Christophe Bilheux. This project was sponsored by the US DOE NEUP.
