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.”

Neutral atom transport in the edge region of fusion plasmas is characterized by extreme geometrical complexity, mean-free-paths that vary from millimetres to metres over short distances, and many orders of magnitude variation in atom density. We have proposed and are developing an interface current integral transport method as a more practical alternative to the Monte Carlo method, which is currently used for such calculations. This particular formulation of interface current methodology is described, the accuracy of the several approximations that are made in implementing the methodology are evaluated by comparison with Monte Carlo, and correction factors and extensions of the methodology, which improve accuracy, are presented. The results are formulated so as to be generally applicable to any neutral particle transport application.
