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 conventional electrorefiners to treat a metallic spent fuel equipped with a steel cathode have a sticking characteristic that hinders their overall processing efficiency. The critical question in order to enhance their throughput is how to decrease the sticking coefficient of the cathode. In order to realize this purpose, the conventional steel cathode was replaced with a graphite one. The graphite cathode exhibited self-scraping behavior in which the electrodeposited uranium dendrite falls from the cathode surface on its own without any kind of mechanical operation such as a scraping and rotation of the electrode. This self-scraping phenomenon of the graphite cathode was interpreted to be due to the formation of a uranium graphite intercalation compound. In this self-scraping mechanism, uranium atoms elongate at the graphite's outermost layer by an intercalation reaction, so the deposited uranium dendrite falls off spontaneously as the gravitational force exceeds the bonding strength of the layers. Based on our preliminary work, a self-scraping should increase the efficiency of an electrorefiner due to the elimination of a mechanical scraping as well as the electrolytic stripping steps of the cathode.
