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.”

In this paper, a thermomechanical interaction of a ceramic breeder pebble bed and structural plate is studied based on a recently developed discrete numerical simulation code. The calculations take into account the coupling effect between structural wall deformation and pebble bed deformation, which greatly increases the computing time and complicates the computational procedures in determining the particle-wall contact characteristics. Specifically, the model is applied to a lithium orthosilicate packed bed for the evaluation of the deformation of a circular plate due to bed thermal expansion, while the results are compared with SCATOLA's experimental data. Numerical results using a fixed boundary condition show reasonable agreement with the experimental data. In addition, numerical simulations confirm an irreversible plate deformation after a thermal cycle run as observed in the experiments, although these experimentally observed deformations are larger than that of the numerical estimations. Moreover, numerical results of contact forces at contact points provide information concerning the mechanical integrity of the bed at a moderately high temperature.
