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 problems of the three-dimensional (3D) plasma confinement systems optimization based on choice of a proper topology of the module B lines on magnetic surface is considered. This approach developed in recent years is connected with the fact that in spite of the 3D structure of the confining magnetic field in the stellarator and mirror with quadrupole stabilizers, an essential properties of the equilibrium and the guiding center drift depend mainly on module B distribution on magnetic surfaces. Selecting the system with the “quasisymmetric” distribution of module B one could to avoid or to make weaker unfavourable effects of the 3-D systems: the island structure and large neoclassical transport. The theoretical base for this approach is discussed.
