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.”

Large glass shells (≥ 1200 μm diameter) made by the traditional drop tower technique are usually thin walled (≤ 4 μm). Therefore, even the highest quality shells cannot hold more than ∼70 atmospheres (atm) of gas pressure. This report describes the strengthening of these shells by over-coating them with Glow Discharge Polymer (GDP). Glass shells overcoated with various thicknesses of GDP were permeation-filled and burst tested. It was found that tens of microns of GDP overcoating significantly increased the strength of the original glass shells. In particular, composite shells able to hold 200 atm of helium were made. The burst test survivors were tested against possible undetected microcracks by confirming that the half-life for the release of the gas from filled shells was consistent with the expected half-life for an intact shell.
