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.”

According to the recent low gas-puff experiments in Hanbit magnetic mirror device, the achievable ion temperature is limited largely by neutral content. For discharges with the low gas-puff with the pre-ionization technique, higher ion temperature is estimated compared to the high gas-puff case. Neutral transport and corresponding particle balance in this low gas-puff discharges in Hanbit are analyzed with the two dimensional Monte-Carlo simulation code coupled with a simple parallel plasma confinement formula. The radial ion temperature and power loss profiles are also derived. The global particle balance is between the plasma pumping and the recycling processes, hence the initially puffed amount of gas has negligible contribution to the total particle source.
