Reliability of NDT results of vessel and component programs (FKS, HDR, PISC, GB)

In the reactor safety projects “integrity of components”, PISC, HDR and “full size vessel” many components with defects and lower bound structure conditions are available. Relevant loading states are simulated. These projects guarantee the further development of all NDT tools, the possibility to prove and to improve the capability of the techniques for the definition of defects, and for the determination of the state of the material (toughness) and the loading conditions. The relevant safety significance of NDT for the description, especially of the area of end of life of a component is demonstrated in such a way.
