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 design of a new type of neutral beam injector that recovers the energy of the unneutralized part of the beam, developed at Cadarache Laboratory, is presented. The experimental work done since 1987 is also reviewed. In a recent joint Japan Atomic Energy Research Institute (JAERI)/Commissariat à l'Energie Atomique experiment, the injector was operated with extracted deuterium ion beams of up to 85 keV/35 A and 100 keV/14 A by utilizing a plasma generator developed at JAERI that supplies up to a 94% monoatomic ion content. From energy recovery measurements, an improvement in the injector electrical power efficiency by up to 25% for a 100-keV deuterium beam operated with a 6 × 1015 mol/cm2 neutralizer gas target thickness is deduced.
