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.”

Synthetic zeolite is the candidate material of the separation column of the gas chromatograph for the hydrogen isotope analysis. Mordenite (MOR) is one of the zeolite, and has been reported that the MOR column can separate hydrogen isotope at about 200K. So, the present authors have investigated the adsorption capacities of H2 and D2 on MOR at various temperatures, and have predicted the adsorption isotherms of HD, HT, DT and T2. In this work, the adsorption capacities of tritium on MOR at 77K and 87K were investigated, and they were compared with the predicted isotherms. The observed isotherm at 87K agreed with the predicted isotherm well in low pressure region. However, at 77K, the adsorption capacity at low pressure region was smaller than that of D2.
