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 Inertial Fusion Reactor KOYO, proposed by ILE Osaka was completed in its first phase study in 1992, and recent updates including new features have been released up to now. It is based on potentially key achievements in Inertial Fusion Energy (IFE) physics: development to achieve required laser efficiency, implosion stability and gain, pellet fabrication, chamber maintenance, engineering feasibilities, and cost of electricity.
Neutron (target) emission profiles are reported assuming direct drive compressed targets (500 g.cm-3), which have been described with different approaches in stationary transport models. A full three-dimensional description of the reactor has been used to perform the neutronic analysis. Neutron spectra and flucnecs are calculated, and compared with previous one-dimensional results showing the differences in using both approaches. Some figures indicating the neutron flux expected through deep penetrations impinging on the final optics are also presented, representing its coincidence at long distances with the uncollided flux.
The reported consequences are those related to the activation of the materials: shallow land burial (SLB) and recycling. Those radiological responses have been studied for the SiC tubes (components of the blanket), graphite (reflector), and ferritic steel HT-9 (structural wall).
