| Abstract Scope |
EUROFER97 is expected to show minor swelling and fuel retention, but quantitative data at large damage doses are scarce. In this study, EUROFER97 samples were irradiated with MeV Au and Fe ions to high damage doses of 50 and 100 dpa between 100 and 400°C.
X-ray diffraction (XRD) analysis shows that irradiation creates tensile lattice stress in the range of up to 0.3 GPa and increased microstrain of up to 10-4. Annealing at 600°C completely relieves lattice stress but not the microstrain. After XRD, samples were exposed to a D plasma at 100°C and low energy (< 5 eV/D) to decorate the created defects with D. D depth profiles were measured using 3He nuclear reaction analysis. At 50 dpa and 100°C irradiation temperature maximum D concentration is only 100 appm which is a factor of two smaller than for 0.6 dpa. At 300°C the D concentration reaches values of non-irradiated Eurofer97. |
