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.”

Recent experimental results of power and particle control in JT-60U with W-shaped pumped divertor are presented. Backflow of carbon impurities towards x point is decreased by the dome as well as by the gas puff from the main plasma. Heat load on divertor plates is reduced by the detached plasma at high density and radiative plasma by neon seeding. Effective helium exhaust is demonstrated for helium-beam-injected plasmas. Results of high-confinement experiments are also shown. Strongly heated ELMy H-mode plasmas are sustained during 9 s without increasing the impurity contamination. High QDTeq ~ 1 is obtained in the low Ip regime of the reversed shear plasmas. Progress in the negative-ion-based neutral beam injection experiments is finally introduced
