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 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. 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.”

Simulation of reactor antineutrino signatures is vital to verify the experimental measurements of antineutrinos emitted from a reactor. It also provides an insight into detector configurations required to monitor different reactor types and potential fuel diversion scenarios. In this study, we perform simulations of antineutrino signatures for light water reactors (LWRs) using the industry standard reactor simulation tools, CASMO-4 and SIMULATE-3. Three different LWR reactors have been modeled, and several diversion scenarios involving uranium dioxide and mixed-oxide fuel have been simulated. The simulation results are also benchmarked with the antineutrino counts measured by the SONGS1 antineutrino detector that was used to monitor the operation of San Onofre Nuclear Generating Station (SONGS), unit 2, cycle 13, during the period 2004-2005. Three-dimensional simulations of the reactor cores have been performed for improved accuracy of the detector response. The dependence of the antineutrino rate on the reactor type, fuel loading pattern, and amount of fresh fuel have also been analyzed.
