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.”

Technical Paper | Characterization of Radioactive Waste in France / Radioactive Waste Management | doi.org/10.13182/NT96-A35260

In France, specifications for long-lived isotopes, which are critical for the safety of intermediate storage and disposal on surface sites, have been fixed. Because a number of these nuclides are pure beta or alpha emitters, a reliable radiochemical inventory of these isotopes requires a rather sophisticated preparative chemistry before radiation measurement. In view of the initial complexity of matrices for various types of waste, the preparation steps constitute a technological limit to the characterization. Therefore, practices eventually developed for synthetic waste may prove insufficient when applied to real samples. For isotopes with half-lives >105 yr, such as 99Tc and 129I, a physicochemical technique, inductively coupled plasma/mass spectrometry, constitutes an attractive alternative to radiochemical procedures. However, the request for high performance and limitations in sample activity does not allow preparative treatments and chemical separations from interfering species to be minimized.
