Ageing phenomena Non-distractive testing Nuclear fuels reprocessing facilities RT TlBr
The nuclear fuels reprocessing facilities are required to perform appropriate maintenances for the ageing phenomena of the facilities. Development of non-destructive testing devices with high detection precision of the defects, small sizes, and lightweights are essential for testing the facilities. In this study, thallium bromide (TlBr) detectors, which have high absorption efficiency for gamma rays, are developed for the application to a radiographic testing (RT) device. The detector performance was evaluated using stainless steel materials used in the actual plant.
