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.”

Differences in technical concepts for direct disposal of spent fuel and for disposal of high-level waste (HLW) from reprocessing are discussed. The preferred emplacement sites for spent-fuel elements are drifts instead of boreholes, which are used for vitrified HLW. The nuclide inventories of uranium and plutonium are considerably higher with direct disposal. The impact of these conceptual differences on the long-term safety of a repository in a salt formation is investigated.The deterministically calculated radiation exposures for direct disposal and for disposal of reprocessed waste are both within the limits of the German licensing criterion. Furthermore, the differences in the radiation exposures are low, so from this point of view, neither concept is preferable. This result is surprising because the higher inventories of uranium and plutonium in the concept of direct disposal have a negligible influence on radiation exposure. It is shown that the layout temperature of a repository is a parameter influencing long-term safety, where higher layout temperatures are favorable.
