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.”

For metal hydride bed disposal, tritium can be exchanged or replaced with deuterium or protium through successive dilution and removal. Analytical expressions are derived to describe the batch isotopic exchange process for metal hydrides with and without isotopic separation by the hydride. For the case without isotopic separation and the hydride being desorbed to the same gas inventory each exchange cycle, simple mathematical expressions are obtained. These equations can be used to estimate the number of exchange cycles needed to reduce the tritium content of a hydride to the desired inventory. Isotopic exchange predictions agreed with experimental results for La-Ni-Al alloys and titanium hydrides.
