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 Thermal Hydraulics Laboratory in the Nuclear Engineering Department at the University of California, Berkeley constructed the Advanced Reactor Control and Operations (ARCO) facility in January 2018 to serve as an advanced reactor control room and operator support system test bed. ARCO is the control room for the Compact Integral Effects Test (CIET) facility that replicates primary-side flow paths and thermal hydraulic behavior of a Fluoride-salt-cooled High-temperature Reactor (FHR) using simulant fluids and scaling principles. ARCO and CIET together affords experimental operating scenarios for control strategy and user interface iterative design and evaluation for FHRs and, more generally, for advanced small modular nuclear reactor designs. Operating scenarios of primary importance for new reactor designs include rapid load-following, startup and shutdown, and multi-module operation. In addition, ARCO supports research and development of specific and new capabilities for nuclear plant control rooms. Specifically, these capabilities consist of new digital communication tools for operators, sophisticated and intuitive means of on-line data analysis, model-based fault detection for online health monitoring and prognostics, and control room cybersecurity strategies. In short, ARCO is a prototypical control system enhanced with operator support capabilities for advanced small modular nuclear reactors. This paper describes the design basis for ARCO and the forthcoming operator support systems operating alongside the CIET facility.
