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.”

Gas nuclear transmutation effects in aluminum nitride were studied by the isotope tailoring method. In this method, nearly identical materials with two different radio-isotopes of nitrogen-14 (Al14N) and 15(Al15N) were prepared. The Al14N and Al15N specimens were irradiated in the JOYO fast reactor and the HFIR thermal reactor. The results were analyzed and compared to accumulated irradiation data from JMTR and JOYO. The data clearly shows the effects of gas nuclear transmutation on the linear dimension change.
