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.”

Two experiments directed to a search the experimental conditions for the creation of the hot plasma bunch with β~1 at the multimirror trap GOL-3-II are described. In the first one the hydrogen cloud of 0.5 m length and ~1016 density cm−3 was heated in a short (~ 0.5 m) section with relatively small magnetic field placed in the 12-m solenoid with 9 T magnetic field in mirrors. Plasma pressure was measured by diamagnetic loops and reached βvac ≈0.4. In the second experiment the dense bunch is created by pellet (LiD, (CH2)n) injection into the electron-beam-heated plasma. After beginning of the beam injection the pellet is evaporated and ionized, then dense plasma is magnetized and as result dense bunch (ne=1016-1017cm−3) with abrupt edges is created. After heating the bunch has expansion velocity up to 3·107cm/s.
