The Munich Accelerator for Fission Fragments MAFF is under design at the new research reactor FRM-II.

After a short overview of MAFF, we will outline the safety concept of this instrument with emphasis on the reactor part, not the post-accelerator part. As MAFF is one among many instruments sharing the FRM-II, a main general safety goal is minimizing the feedback of potential failures to the reactor. In particular, in-pile parts of MAFF must not affect reactor safety. This causes constraints, e.g. for the layout of the target/ion source assembly.

Some potential failure szenarios will be discussed as well as techniques for radioactivity handling.
