Removal of excess oxygen in a MOX fuel element during the irradiation is required to attain a high burn up of FBR fuel because the increase of the oxygen potential in a fuel element during the irradiation accelerates FCCI. The oxygen getter method is an alternative to the low O/M ratio pellet option. Preliminary surveillance suggested Zr and Ti were most expecting candidates. In this study, the compatibility of these candidate materials with MOX, UO $_{2}$ and FMS as well as their oxygen uptake abilities were evaluated.
