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.”

This paper describes the thermal and mechanical influence of a single level conceptual deep geological repository (DGR) in a hypothetical crystalline host rock geosphere on the ground surface. Sensitivity studies are performed to investigate the influence of Young’s modulus for the rock, the depth of the repository and the convective heat transfer coefficient applied at the ground surface. The influence of the mechanical boundary condition applied on the far-field vertical surfaces is also studied. For the cases evaluated, the presence of the conceptual DGR does not have any significant influence on the surface temperature. There is a general slow uplift of the ground surface due to thermal expansion over an area larger than the repository footprint, with a maximum uplift of about 28 cm occurring above the centre of the repository occurring after about 3,400 years. No mechanical damage to the rock comprising the ground surface is anticipated.
