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.”

Radial particle transport in GAMMA 10 was investigated under a quasi-steady state condition plasma. The transport analysis was carried out with changing the boundary conditions, in order to reconstruct the density profile which is consistent with the measured data. From the above result, the best fit profile to the measured one was obtained with the diffusivity of 0.57 m2/s. The particle diffusivity in an additional gas puffing experiment was estimated. The result of the transport analysis was also compared with the diffusion coefficient expected from classical diffusion processes.
