Gamma Scanning of CANDU Fuel
Main Article Content
Abstract
A versatile gamma-scanning system with high spatial resolution, has been developed for the nondestructive measurement of fission-product distributions in used fuel elements and glass waste forms. The instrument permits real-time data acquisition and analysis. Gamma scanning is used to
characterize fuel for leaching and dry storage programs. In the fuel leaching studies, the gamma scanner has been able to detect a 3% loss of cesium from an intentionally defected fuel element. Burnup of Pickering and Bruce used fuel has been calculated from measurements of the average gamma scanning 137Cs activity.
