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.”

An instrumentation of X-ray absorption spectroscopy (XAS) was developed to measure the areal density of any element with an atomic number Z > 17. In contrast to X-ray fluorescence, which is affected by spatial dopant nonuniformity, an element can be accurately measured by XAS regardless of its own distribution or the presence of other elements in a sample. Furthermore, no reference standard is needed to achieve ±3% 1 accuracy. This method has been used to measure the average contents of specific elements in a variety of inertial confinement fusion and high energy density targets. It validates the average dopant concentration measured by contact radiography and differential radiography.
