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.”

The first wall and the divertor in present-day or next step thermonuclear fusion devices are exposed to intense fluxes of charged and neutral particles, in addition the plasma facing materials and components are subjected to radiation in a wide spectral range. These processes, in general referred to as `plasma wall interaction' will have strong influence on the plasma performance, and moreover, they have major impact on the degradation and on the lifetime of the plasma facing armour and the joining interface between the plasma facing material and the heat sink. Beside physical and chemical sputtering processes, thermal fatigue damage due to cyclic heat fluxes during normal operation and intense thermal shocks caused by severe thermal transients are of serious concern for the engineers which develop reliable wall components. In addition, the material and component degradation due to high fluxes of energetic neutrons is another critical issue in D-T-burning fusion devices which requires further extensive research activities. This paper represents a tutorial focussed on the development and characterization of plasma facing components for thermonuclear fusion devices.
