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.”

A phase-shifting diffraction interferometer provides full surface mapping of National Ignition Facility (NIF) ablator capsules for surface finish and isolated defects. To integrate this new instrument into the NIF metrology work flow, the measurement must be both quick and accurate. In this work, we developed automated processing algorithms to streamline a large number of manual steps. This enables the process time to be reduced from 1½ days to 2 h per shell, thus meeting the NIF throughput requirement of 20 capsules/week. We also developed methods to quantitatively report the isolated defects and surface roughness in formats that can be benchmarked against the NIF specifications.
