Desorption of Implanted Deuterium in Heavy Ion-Irradiated Zry-2

چکیده
To understand the degradation behavior of light water reactor (LWR) fuel-cladding tubes under neutron irradiation, a detailed mechanism hydrogen pickup related to point defect formation (i.e., a-component and c-component dislocation loops) dissolution precipitates must be elucidated. In this study, 3.2 MeV Ni3+ ion irradiation was conducted on Zircaloy-2 samples at room temperature. Thermal desorption spectroscopy is used evaluate deuterium with without irradiation. A conventional transmission electron microscope spherical aberration-corrected high-resolution analytical are observe microstructure. The experimental results indicate that radiation-induced loops hydrides form in act as major trapping sites lower (400–600 °C) higher (700–900 °C)-temperature regions, respectively. These show microstructural changes sinks formed by necessary for LWR during operation.

متن کاملAvoiding preamorphization damage in MeV heavy ion-implanted silicon
Implantation of 1.0 MeV ‘isIn in Si results in secondary-defect formation during subsequent 900 “C annealing if the total number of displaced Si atoms is greater than 1.6~ lOi’/ cm’, achieved with a dose near 1.5 X 10i3/cm2. We demonstrate, though, that higher total In doses can be introduced without forming secondary defects by repetitive subthreshold implants each followed by an anneal to rem...
