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 potential value of probabilistic risk assessment (PRA) tools to fusion safety and economic issues is discussed. The main results and implications of a systematic examination of these general issues via PRA tools are reported. It is concluded that PRA methodology, tools, and thinking are useful to fusion research in the process of further improving fusion concepts and ideas. The MARS and STARFIRE designs are examined for possible answers to questions posed by using PRA tools. Several general magnetic-fusion design insights result from the study, including the following: 1. possible fault interactions must be minimized by decoupling fault conditions 2. the reliability of the vacuum boundary appears vital to maximizing facility availability and minimizing safety risk 3. economic analyses appear to be incomplete without consideration of potential availability loss from forced outages. A modification to PRA formalism called the “fault interaction matrix” is introduced. The fault interaction matrix contains information concerning what initial fault condition could lead to another fault condition, with what frequency. Thus, the fault interaction matrix represents a way to present and measure the degree to which a designer has decoupled possible fault conditions in his design. Such decoupling is crucial to enhancing fusion safety and facility availability.
