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.”

Coldfusion of deuterium by electrolysis of heavy water onto a palladium (or titanium) cathode has been reported. Contrary to the assumption of Fleischmann and Pons that electrochemically compressed D+ exists inside the palladium cathode, the observations of Jones et al. can be partially explained by the simultaneous presence of deuteride D− and the highly mobile positive deuterium ion D+. The opposite charges reduce the intranuclear distance and enhance the tunneling fusion rate. Furthermore alloying of lithium with palladium can stabilize a negatively charged deuteride ion due to the salinelike character of lithium deuteride. The enormous pressure (or fugacity), achieved by the applied electrochemical potential (1030 atm), is a virtual pressure that would have existed in equilibrium with palladium deuteride (PdDx). It is speculated that nuclear fusion occurs at the surface, and the PdDx serves as a reservoir for the supply of deuteride ions.
