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.”

Compact, tight aspect ratio toroidal configurations offer a set of properties favorable for fusion ignition experiments. High magnetic fields support high particle densities, which increase the fusion reaction rate and improve the plasma purity, as well as high plasma currents, which provide strong ohmic heating and keep the plasma beta low to improve stability. Low temperature D-T ignition. To ≤ 15 ke V, at relatively low levels of fusion α-particle heating compared to the ohmic heating, Pα/POH ≤ 2, then becomes possible, using predominantly ohmic heating. This minimizes the degradation of plasma confinement caused by injected heating and high beta and also reduces the need for complex divertor systems.
