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.”

Fissile fuel producing blankets for both D-D and D-T fusion reactors are designed based on a slurry concept. In the designs, the blanket is composed of a slurry of ThO2 particles carried by heavy water. The slurry serves both to cool the reactor and to breed fissile fuel. Neutronic and photonic calculations showed that the slurry blankets achieved performance comparable to alternative concepts (moltensalts, fixed fertile material). For the slurry concept to be useful for a D-T reactor, a neutron multiplier needed to be used. The fast fission rate in the slurry blankets was small. Fission of the bred fissile material can be limited by removal of the ThO2 particles for processing after 5–10 days of irradiation.
