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.”

The adsorption behavior of H2O on Li2O surface was studied by ultra violet photo electron spectroscopy (UPS). Valence-band spectra of Li2O single crystal which was exposed to different pressures of H2O vapor were recorded. After exposure of H2O, variation of the spectra was observed. The observed spectra were interpreted on the basis of ab-initio quantum chemical calculation of the electronic structure of Li2O surface which was covered with –OH. The adsorbate-induced features were assigned as the orbital of surface –OH. The surface condition was varied by Ar ion sputtering and heat treatment under D2 gas. The difference of adsorption behavior of H2O in the surface condition was discussed.
