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.”

Ion-driven permeation of deuterium was studied through an iron (0.1 mm thickness) coated with a SiO2 of about 30 nm thick. A flux ratio of permeation/incident for the Fe sample ranged from 7.6 × 10−5 at 373 K to 1.4 × 10−3 at 673 K for the incident ion flux of 6.4 × 10−18 ions m−2S−1 at the ion energy of 0.3 keV. The permeation flux through the back coated sample is lowered by a factor of 1 or 2 orders of magnitude than the case of the Fe sample. The activation energy(0.2eV) of the permeation of these two samples are almost same. As for the front coated sample, the different energy and incident ion flux dependences were observed. Investigations of the SiO2 coating property under deuterium ion implantation by XPS showed that the coating on the front surface could easily sputtered away during the experiments. Thus, the surface after removing of the coating has a special condition that changes the properties of permeation.
