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.”

Bifurcation phenomena with confinement improvement in toroidal plasmas are briefly reviewed. After a general discussion of the formation mechanisms of improved confinement modes, the electron internal transport barrier commonly observed in stellarators is chosen here as the main subject with focus on the following aspects: the bifurcation property, the scenario of bifurcation with confinement improvement, and the confinement features. Several works to investigate the relationship between rational surfaces and barrier formation are introduced as examples to show the relation between magnetic topology and the bifurcation property. The roles of stellarators, which have a wide variety of configurations, for understanding bifurcation phenomena are discussed.
