Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

Radiation effects in beryllium as produced by fast neutrons and resulting in dimensional changes are reviewed. It is found that helium bubble swelling is the predominant mechanism; however, because of the intrinsic anisotropy of the dislocation structure, bubble swelling is expected to be anisotropic, accompanied by radiation-induced growth. The anisotropy of swelling and plastic deformation at the microscopic level of crystal grains eventually results in microcracking, and the total inelastic deformation should therefore not exceed about 1%.
