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 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. 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.”

Glass shells made from the pyrolysis of silicon-doped glow discharge polymers (Si-GDP) are particularly interesting for many noncryogenic target applications. We investigated the possibility of developing millimeter glass shells with >10-m-thick walls to achieve a half-life of several months. Although previous studies have already demonstrated their feasibility, important developments are still needed to finely understand the role each step plays on the final glass shell's properties. The adjustment of plasma deposition parameters and pyrolysis conditions allowed us to control shell shrinkage and defect formation. In the case of 7.4 at. % Si-GDP slowly pyrolyzed, we obtained spherical and smooth glass shells with near 100% yield. We also demonstrated that adjusting sintering temperature can produce fully dense glass shells from 2.2 to 2.4 g/cm3 . Finally, deuterium pressurized capsules >3 MPa with a half-life of 8 months are obtained.
