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.”

Methods for incorporating magnetohydrodynamic equilibria and internal instabilities into tokamak transport codes are reviewed with emphasis on how the models may be extended to reactor plasmas. Instabilities are characterized from a computational view as being either intermittent or continuous modes. Intermittent disturbances are treated adiabatically whereas saturated instabilities can be handled through enhanced transport coefficients. The m = 1/n = 1 mode serves as an example of how the character of an instability can change as we proceed from low-beta resistive plasmas to high-beta collisionless plasmas. The implications for reactor thermal dynamics of finite-beta-induced transport are discussed in terms of Impurity Studies Experiment-B observations and analysis.
