XRay Radiography for Post Irradiation Examination on Fuel Rods

The Xray radiograph is one method for post irradiation examination on fuel rods. It is used to observe position change of UO2 pellets in fuel cladding. The fuel rod possessed high radioactivity slightness shape. The laboratory structure, image facility, experiment parameter were introduced. The results showed that the designed facility was suitable for post irradiation examination on fuel rods.
