Abstract Scope |
Advanced reactors require structural materials that can withstand levels of stress, temperature, and irradiation that have never been experienced before. Accordingly, one of the dominant failure mechanisms of structural components is expected to be irradiation creep. This demands an explicit focus on testing candidate materials under representative environments. The Michigan Ion Beam Laboratory has developed an ion irradiation creep testing rig that can subject thin (30 μm) samples to tensile stresses up to 316 MPa, temperatures up to 500°C, and doses up to 0.4 dpa. Furthermore, in-service loading conditions may not be constant, requiring the ability to investigate irradiation creep fatigue environments. Recent developments on the installation of a miniature tensile rig onto the accelerator beamline will also be presented. These facilities will enable the generation of multi-dimensional datasets investigating the irradiation creep dependence on either stress or temperature within a single experiment, thus accelerating understanding in nuclear materials science. |
