Surface and solid state analysis

The surface and solid state analysis (OFA) group (one of the two analytical groups of the division HOTLAB) operates a couple of analytical tools to examine the surface of radioactive material during post irradiation examination (PIE) and research projects.

PIEs are mostly related to Swiss light water reactor (LWR), which are including investigations on the complete fuel rod system. Also in the international world, OFA act on PIE activities with different partners.
In the field of research activities OFA collaborates predominantly with internal PSI organizations. Swissnuclear (SN) and the European Community (EC) are predominantly backers for projects related to safety issues and vendors questions in the field of new fuel types and cladding tube behavior at different service conditions in the reactors. The most important tool operated by the group are:
