The following is a Georgia Power news release:

Major systems testing is underway at Georgia Power’s Vogtle 3 & 4 nuclear expansion project near Waynesboro, Georgia, as the site continues to transition from construction toward system operations. The latest phase of testing, Open Vessel Testing, will demonstrate how water flows from the key safety systems into the reactor vessel ensuring the paths are not blocked or constricted.

Open Vessel Testing will also confirm that the pumps, motors, valves, pipes and other components of the systems function as designed. It follows the Integrated Flush process, which began in August, to push water through system piping and mechanical components that feed into the Unit 3 reactor vessel and reactor coolant loops for the first time. Integrated Flush will clean and remove any foreign material ahead of the initial startup of the unit.
