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.”

Accuracy and abilities of the electron cyclotron emission (ECE) diagnostic system planned to be installed in the Wendelstein 7-X stellarator are analysed with help of ray-tracing simulations. For the expected plasma parameters, the spatial resolution of the standard low-field-side (lfs) X2-mode observation scheme is estimated to be sufficiently high, ~5%. Apart from the lfs scheme, the applicability of other complementary schemes is analyzed, in particular, high-field-side (hfs) X2-mode observation. It is shown that in combination with the standard lfs scheme, the hfs scheme can be very informative for the problem of distinguishing thermal and nonthermal contributions in the ECE spectrum.
