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.”

Adsorption of H2O on the -Al2O3 (0001) surface was studied by means of a first-principles calculation based on density functional theory (DFT). We also investigated the behavior of the isotope exchange by substituting a protium atom with deuterium or tritium. The oxygen atom of H2O adsorbs on the Al atom of the outermost surface layer, the entire water molecule is slanted at the direction of a hollow site, and a molecular plane is nearly parallel to the surface. The adsorbed states are mostly due to coupling of lone-pair electrons of H2O with the empty p orbitals of the Al atom of surface. The behavior of dissociation for H2O is clarified from molecular dynamics simulations, indicating that the second neighbor oxygen atom is more preferable adsorption site for dissociation than the nearest neighbor oxygen atom on the surface.
