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.”

A new model describing the transfer of neutrons to and from nuclei embedded in a lattice was recently proposed. The coupling between the nuclei and lattice phonons is now explored, focusing on the question of whether it is possible under any conditions for anomalously large energy transfer to or from the lattice to occur during a neutron transfer reaction. By studying the gamma line shape, no anomalies are expected for a ground-state lattice or for a thermal lattice. Under certain conditions, the frequency of aphonon mode can be shifted significantly in a neutron transfer reaction; phonons initially present in that mode are shifted in frequency during the reaction. This effect produces an anomalous energy shift in the event that the mode is initially strongly excited.
