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 capabilities of new methods of fusion alpha-particle diagnostics based on nuclear reactions are discussed. Particularly, the resonant capture reactions between confined fast alpha particles and low-Z artificial impurities in the plasma is examined. In this case, the intensity of the decay gamma rays is proportional to the alpha-particle concentration at resonance energy. Another method is based on Doppler shape analysis of the 4.44-MeV gamma-ray spectra from the 9Be(α, n1γ)12C reaction. Results of an in-beam study of this diagnostic reaction are given. Some questions concerning the gamma spectrometer, a collimator, and a radiation shield are discussed. Estimates of the reaction rates and signal values in the Tokamak Fusion Test Reactor, T-14, Compact Ignition Tokamak (CIT), and International Thermonuclear Experimental Reactor (ITER) are presented. In conclusion, the use of gamma spectroscopy in the diagnostics fusion protons in deuterium-deuterium plasma is examined.
