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.”

A pulsed fusion reactor potentially influences many commercial plant design provisions. Provisions related to turbine fatigue performance are among those considered important. They are evaluated by varying several design/operating parameters, separately and in combination, to present tradeoffs among them. These parameters include pulse length and capacity of the thermal storage system. A very simple and fast running temperature/stress representation of the turbine is used for evaluations. Results for wet-steam turbines indicate that requirements for thermal storage are quite large (steam flow between 40 and 80% of full steam flow). Modeling assumptions, design options, and important operating considerations are highlighted.
