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.”

The INEEL has analyzed a variety of dust samples from operating experimental tokamaks: General Atomics' DIII-D, Massachusetts Institute of Technology's Alcator CMOD, and Princeton's TFTR. These dust samples were collected and analyzed because of the importance of dust to the safety of future fusion power plants and ITER. The dust may contain tritium, be activated, be chemically toxic, and chemically reactive. The INEEL has carried out numerous characterization procedures on the samples yielding information useful both to tokamak designers and to safety researchers. Two different methods were used for particle characterization: optical microscopy (count based) and laser based volumetric diffraction (mass based). Surface area of the dust samples was measured using Brunauer, Emmett, and Teller, BET1, a gas adsorption technique.
The purpose of this paper is to present the correlation between our particle size measurements and our surface area measurements for tokamak dust.
