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.”

The plasma generated in a spherical pinch device consists of a linear discharge along the diameter of a spherical vessel and of an implosion that compresses the linear plasma. Because the linear discharge by itself is found to emit pulses of soft X rays, this phenomenon is investigated by considering a spatially uniform plasma subjected to an electric field. With an appropriate change of variables, a one-dimensional time-independent Boltzmann Fokker-Planck equation is transformed into a confluent hypergeometric equation. The electron distribution function is then calculated in closed form together with the density current to obtain the X-ray spectra from such plasmas.
