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 High-Yield Lithium-Injection Fusion Energy (HYLIFE)-II conceptual reactor design uses stationary and oscillating slab jets, or liquid sheets, of molten Flibe (Li2BeF4) to shield the chamber first walls from damaging neutrons, ions, and target debris. A lattice of stationary liquid sheets with the beams propagating through the lattice openings is used to protect chamber front and back walls. Extremely smooth sheets are required to effectively shield the chamber first walls without clipping the driver beams. Surface ripple and its growth are therefore a major concern in liquid protection design.
In this study, a non-intrusive technique for directly visualizing and measuring the instantaneous free-surface geometry has been developed. Mean free-surface geometry and surface geometry fluctuation results for turbulent water sheets issuing vertically downwards into atmospheric pressure air are presented at Reynolds numbers based upon the nozzle thickness of 34000, at distances up to 25 nozzle thicknesses (25δ) downstream of the nozzle exit.
