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.”

Recently, pre-ionization experiments using thermal electron emission from LaB6 cathode and electron heating by 2 kW@14.5 GHz Klystron installed at cusp and plug cell respectively have been carried out in Hanbit mirror device. Charge exchange collision between ion and neutral atom has been concerned as an important mechanism of ion energy loss in the Hanbit discharges, hence the high pressure of neutral particles is one of the most reasonable cause of low ion temperature. In this work, we investigate low pressure operation mode with help of the pre-ionization to enhance the ion temperature. The ion temperature and temperature anisotropy are measured and also inferred by ELA(End Loss Analyzer) for central cell plasma. We also characterize RF heating properties for different regimes of /c0i using simulation code for electromagnetic waves.
