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.”

About 70 single-rod quench tests with fresh and preoxidized Zircaloy specimens are carried out at Forschungszentrum Karlsruhe with water and steam as quench media. A number of mechanical effects are observed on the cladding of the test rods by posttest examination; the most important ones are the occurrence of through-wall cracks mainly for thick oxide scales and a severe degradation of the -phase for water-quenched and steam-cooled tests.Calculations of some tests are done with the WSPAN one-dimensional rod mechanics code. This code calculates a very high stress pulse in the oxide scale occurring at the phase transition in the oxide phase. With the assumption of purely elastic behavior of the -phase at the high strain rates occurring at the phase transition, the cracking in the -phase and the formation of through-wall cracks can be understood.
