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.”

Energetic particle effects on MHD stability of a tandem mirror plasma is studied theoretically. An algebraic dispersion equation with respect to eigenfrequency is derived from a radial eigenmode equation for flute-mode perturbations with an appropriate boundary condition, in which the effects of energetically drifting ions are taken into account. The dispersion equation describes interactions between curvature-driven interchange modes and drift modes driven by energetically drifting ions. In the absence of wave-particle interactions for energetically drifting ions, the dispersion equation is solved numerically, and a stable region formed due to the charge uncovering effects of energetically drifting ions is shown in a parameter space related with the number density and magnetic drift frequency of energetically drifting ions.
