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.”

Three-dimensional Monte Carlo analyses were performed for the three-legged beam ports of the laser fusion reactor SENRI-I. The validity of two devices for attenuating neutron flux was examined, and it was shown that the fast neutron flux attenuation of 1.4 × 105 can be reached by adopting these two devices in combination. The effectiveness of variance reduction techniques was also examined. It was determined that path length stretching was useful when it was used for neutron groups above 1 MeV. Adopting adjoint flux-dependent Russian roulette weight cutoff also seemed useful.
