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 Tritium Emissions Reduction Facility (TERF) is an automated process that continuously removes tritium from process gases before they are discharged to the atmosphere. Key control parameters include: temperature, pressure, flow, oxygen content, total combustibles, moisture concentrations and tritium concentrations. The procurement of an industrial, microprocessor-based Distributed Process Control System was justified for TERF due to the critical nature and complexity of the system. A detailed performance specification was prepared and submitted to industrial companies who had demonstrated past success in the field of process control and instrumentation. The contract was awarded to the Foxboro Company, of Foxboro, Ma., who developed the new Intelligent Automation (I/A) Distributed Process Control System. A primary goal of the design team was that the control system increase TERF reliability and availability by automatically controlling system operation and by assisting the operator in the diagnosis of problems, preventative maintenance, alarming, report generation, and long term storage of data. The comprehensive continuous monitoring of the TERF process provided by the Foxboro I/A Distributed System is expected to: (1) optimize the system operating parameters and control the process better than was previously possible, (2) provide more alerts and alarms to aid operators in diagnosing and responding to problems, and (3) record and organize process data more effectively than before.
