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.”

In the GAMMA10 tandem mirror, ion cyclotron range of frequency (ICRF) waves are effectively used for the plasma production and heating. Alfvén ion cyclotron (AIC) modes are spontaneously excited due to the strong heating. Stability boundary for the AIC modes is analyzed by introducing the effective mirror ratio. It is shown that the AIC modes become more unstable with smaller mirror ratio. The pitch angle scattering of the high energy ions due to the AIC mode are clearly observed.
