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.”

Double-peaked energy spectra of deuterium-deuterium protons have been observed from laser implosion experiments at the University of Rochester. These spectra have been used to study implosion dynamics. The energy and broadening of the two peaks relate to distinct burn phases, shock coalescence, and compression. Data are obtained by unfolding the spectra. Using a model for changing target ρR conditions, the proton energy loss and the broadening of each peak determine the fuel compression and temperature for each burn phase. An ion temperature for the shock phase is determined from thermal broadening. The compression peak's energy broadening and separation from the shock peak is fit to an adiabatic temperature model. Preliminary data suggest that temperatures during both burns are 20% below that predicted by an extensive simulation code. Compressions are also lower than predicted.
