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.”

We are performing research and development to increase production quantity and yield for Inertial Fusion Energy targets for laser fusion. A key component of the laser fusion target is an approximately 4 mm diameter foam shell. To facilitate large-scale production, research into optimization of foam shell gelation and hardening times to reduce non-concentricity of the foam shell is underway. Additionally, we are examining methods to modify the current laboratory bench scale process for initial foam shell formation, various fluid exchanges, and sealcoat chemistry into a continuous process in collaboration with Schafer Corporation. The proposed process utilizes porous tubing sections to perform fluid exchanges in a long (200 m-1 km) continuous path of tubing extending from the triple orifice generator currently used to encapsulate and form the foam shell.Real-time process control has been applied to the triple orifice generator to control the diameter of the foam shell. The system makes use of a pair of photodiode sensors in a closed loop feedback control system incorporating a variable speed process pump. Empirical results indicate the process control loop is capable of identifying wet shell diameters to an approximate standard deviation of 80 to 90 m, on par with characterization results indicating true shell diameter standard deviations of 30-80 m.
