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.”

ARIES-I incorporates modest extrapolation of existing physics with advanced technology in the fusion-powercore design. The ARIES-I design implements a modular approach to fusion-power-core assembly and maintenance. The removal and installation of components is performed more quickly using a modular design by eliminating subtasks which are performed in a hot-cell while the reactor resumes operation and goes back on-line. The maintenance scenario for ARIES-I has been outlined and the major tasks have been identified.
