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 TJ-II device is a medium-size (R0 = 1.5 m, 〈ap〉 = 0.2 to 0.25 m, B0 = 1 T) helical-axis stellarator to be built at the CIEMAT site in Madrid. Its main characteristics are (a) potential for high-beta operation; (b) flexibility, i.e., its rotational transform can be varied over a wide range and its shear to some extent; and (c) bean-shaped plasma cross section. The latest understanding of TJ-II physics in the fields of electron cyclotron resonance heating, transport, and magnetohydrodynamics, and the engineering solutions introduced in its final design are discussed.
