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 ARIES team is presently studying a fusion power plant based on the spherical tokamak (ST) concept. This paper addresses the key nuclear issues for spherical tokamaks and illustrates the impact of the neutronics factors on the ARIES-ST design. A three-dimensional analysis was carried out for an interim design to determine the key nuclear parameters. Preceding the 3-D analysis, a series of parametric 1-D analyses were performed to guide the design toward the final configuration. Comparing the 1-D and 3-D results, important differences were identified and attributed mainly to the angular distribution of the incident source neutrons on the first wall. Those differences are unique to spherical tokamaks.
