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.”

A systematic study of magnetic designs has been carried out for three-cell choke coil quadrupole-stabilized tandem mirror reactors, comparable in size to the (octopole) MINIMARS design. In these designs, a single-mirror cell at each end of the machine serves as an end plug, thermal barrier, and magnetohydrodynamic anchor. The multiple functions of the end plugs make it difficult to simultaneously optimize the physics properties of the plasma (stability, radial confinement, and good particle drift orbits). Two different design approaches have been studied using recently developed magnetic optimization techniques. Typical physics figures of merit are given and critical issues discussed for each design. When the various constraints associated with the high-field choke coil are taken into account, it is found that an acceptable design is beyond the reach of present technology.
