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.”

The complexity of Compact Stellarator (CS) coils made from brittle A15 SC alloys results in a challenging design. Three options of manufacturing the ARIES-CS coils are discussed. The first two options use high performance Nb3Sn superconductor, one with the wind-and-react method, the second with react-and-wind. The magnet protection design philosophies are different for the two winding methods. Wind-and-react uses high conductor current with external dump, while react-and-wind uses low conductor current with internal dump. The use of non-uniform internal quench is explored as a means to minimizing the requirements for internal dump for the case of react-and-wind. Cooling of the superconductor is also fundamentally different in the two cases, as the hydraulic path of the react-and-wind option requires low velocity He in a sheathed Rutherford-like cable, cooled by a heat exchanger in accessible regions. In the third design option, HTS superconductors are deposited directly on the structure, minimizing conductor movement. Coil protection techniques will be described.
