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.”

The fatigue and creep-fatigue response of OFHC copper with three different grain sizes has been studied. Tests were carried out at room temperature and hold times were applied at maximum tensile and compressive strain to simulate the creep effect. The results show that fatigue life decreases with increasing grain size for a fixed applied strain range. Hold times resulted in a major reduction in the number of cycles to failure. This reduction was largest at the lowest strain amplitudes and the longest fatigue lives, the region of most interest for component design. The large reduction in fatigue life is apparently due to a change in the crack initiation mode from transgranular in continuous cycle fatigue to intergranular in creep-fatigue conditions.
