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 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. 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 heat flux split is one of the important technical issues in dual-cooled annular fuel. The inner and outer diameters of an annular pellet should be carefully controlled because they determine the inner and outer gap sizes and thereby influence the balance in a heat flux split. The outer diameter of a sintered annular pellet can be controlled to a final uniform size by a centerless grinding. However, it is difficult and unproductive to grind the inner surface of all annular pellets. To obtain a uniform inner diameter among annular pellets and to minimize a diametric tolerance without inner surface grinding, we applied a rigid rod-inserted sintering process to the annular pellet fabrication. An annular compact was first compacted with a double-acting press and then sintered with a precisely machined rigid rod inserted. The rigid rod can prevent an inhomogeneous deformation of the inner surface during sintering, and thus it controls the inner diameter of the sintered annular pellets and reduces the inner diametric tolerance of a sintered annular pellet without inner surface grinding.
