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.”

Plasma deposition techniques have been examined for production of air-stable films consisting principally of beryllium and carbon. By plasma polymerization of diethylberyllium, films have been made with Be content above 50%, O content near 1%, excellent composition uniformity and reasonable surface smoothness. It appears necessary, for oxygen stability, to deposit these films at T>250°C; at that temperature, the Be is incorporated, at least in part, as a carbide; the measured film densities—2.1–2.5 g/cm3, are near that of Be2C. Permeability to H2 is sufficent to allow microballon filling at 105°C without subsequent loss of H2 at room temperature. Combined sputtering of Be and deposition of a methane plasma polymer has been found similarly effective in forming beryllium/carbon films with Be content above 50 at. % and O content near 1%. These films have not been as extensively studied.
