Open Vessel Testing, a major systems testing milestone, has been completed for Unit 3 at Georgia Power's Vogtle 3 & 4 nuclear expansion project near Waynesboro, Georgia, marking one of the most significant accomplishments in the project to date.
Open Vessel Testing has successfully demonstrated how water flows from the key safety systems into the reactor vessel ensuring the paths are not blocked or constricted. It also prepares Unit 3 for cold hydro testing and hot functional testing – both critical tests required ahead of initial fuel load. The milestone has confirmed that the pumps, motors, valves, pipes and other components of the systems function as designed.
