Feasibility study of oxygen getter materials for FBR MOX fuel, 3; Evaluation for the titanium roll pellet method

Morihira, Masayuki 

Cladding inner corrosion is one of the life control factors of FBR MOX fuels. Because excess oxygen during fission brings the corrosion, oxygen getter option was proposed and a feasibility study has been conducted. In the previous study, an option was proposed to locate getter titanium in the lower end of the upper axial blanket region of a fuel element. Also the titanium roll pellet method was proposed to reduce the smear density of the getter titanium to absorb the swelling during the oxidation. In this study, producibility of titanium roll pellets and their oxidation behavior were evaluated.
