Web1 mei 2024 · In addition, the number density of the observed dislocation loops increases with increasing the helium injection ratio at 300 °C, rather than 450-°C irradiation. This result indicates that irradiation hardening increases with increasing the helium injection ratio at 300 °C, which is consistent with our recent report. WebVarying the helium injection point permitted the localization of the leak to a single 30/sup 0/ toroidal sector of the vessel. The more » exact location of the leak was found from inside the vessel by spraying helium on suspect regions, while sweeping the contents of the cooling channels to the foreline of a Varian Contraflow leak detector with a 0.1 Pa m/sup 3//s …
