An extended site search can be used within the framework of container development. In this context, the application of a new development methodology also allows for concept planning independent of a host rock. The methodical approach will be shown in this presentation, and it will contribute to maintaining and extending the state of the art in science and technology in the process of repository searches. The aim is continuous further work on the topic of repository container development.
Further investigations of the reorientation behaviour of hydride precipitates in cladding tubes from zircaloy-2 under interim storage conditions have been carried out. The results show that, even below tolerated temperature and stress states, reorientation occurs when the hydrogen contents are low. The hydrides in some cases extended through a wall in the experiments. This shows the need for further investigation regarding alloys that take up small hydrogen amounts.
