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.”

Hydrogen production with a fast breeder reactor (FBR) may be attractive as a long-term energy source with nuclear fuel breeding. The thermochemical and electrolytic hybrid process is one of the hydrogen production methods using a sulfuric acid cycle with the maximum temperature at 500°C, which can be supplied by a sodium-cooled FBR. In this study, a hydrogen production plant with the thermochemical and electrolytic hybrid process has been designed, and the hydrogen production efficiency has been evaluated. The structural materials of the components in the system are steels such as high-Si cast iron, which has good toughness against sulfuric acid. High hydrogen production efficiency of 44% (high heating value) is achieved assuming development of high-efficiency electrolysis.
