In the framework of the German Reactor Safety Programme, as well as many large nuclear components, three full-scale pressure vessels areavailable. With them, the capability of modified and newly-developed NDE techniques has been demonstrated under in-situ conditions. It is shown how different techniques such as ultrasonics, potential drop and acoustic emission can detect and characterise various defect configurations.
