The Tritium Laboratory Karlsruhe (TLK) is developing processes, devices and measurement techniques for the fuel cycle of fusion reactors. Several tritium processing components from tritium operations of experimental and infrastructure facilities of TLK have reached the end of their useful lives, are no longer useable or are to be reconditioned for future use. These components are in the process of post-service examination to determine the condition of the working materials inside these components and the changes that have resulted from operation with hydrogen isotopes, predominantly tritium. Another important aspect is the preparation of some of these components, particularly metal hydride storage beds, for safe disposal. The results are of importance for the design, operation and particularly decommissioning of components of present and future tritium facilities and processing plants, such as JET and ITER. The activities are ongoing and the results to date are presented together with plans for future work.
