ATLANTA, July 14, 2020 /PRNewswire/ -- Closed Vessel Testing has been completed for Vogtle Unit 3 at Georgia Power's nuclear expansion project near Waynesboro, Ga., marking continued progress with critical testing. The completion of this milestone prepares Unit 3 for cold hydro testing, which is required ahead of initial fuel load.
Closed Vessel Testing verifies the pipes and valves in the Unit 3 reactor coolant system were installed as designed and helps ensure safety systems function properly. To carry out Closed Vessel Testing on the plant's passive safety systems, workers installed the reactor vessel head as well as the lower and upper reactor internals and flow restrictors. These will be used during hot functional testing to mimic flow through the reactor core.
The passive safety systems are unique to the AP1000 design and require no operator actions. These systems use only natural forces such as gravity, natural circulation and compressed gas to achieve their safety function. No pumps, fans, diesel engines, chillers or other active machinery are used, except for a few simple valves that automatically align and activate the passive safety systems.
"The completion of Closed Vessel Testing is a major milestone for the project, as we continue to make progress with critical testing and in our transition from construction towards system operations," said Glen Chick, Executive Vice President of Vogtle 3 & 4 Construction.
2020 Key Milestones Achieved
With more than 7,000 workers on site, and more than 800 permanent jobs available once the units begin operating, Vogtle 3 & 4 is currently the largest jobs-producing construction project in the state of Georgia.
Benefits to Customers
The new Vogtle units, with regulatory-approved in-service dates of November 2021 for Unit 3 and November 2022 for Unit 4, are an essential part of Georgia Power's commitment to deliver safe, clean, reliable and affordable energy for customers. Once operating, the two new units at Plant Vogtle will be able to power more than 500,000 homes and businesses and provide customers with a new carbon-free energy source that is expected to put downward pressure on rates for 60 to 80 years. A diverse fuel mix, including nuclear, is also essential to maintaining a reliable and affordable energy infrastructure that attracts new investment, supports economic growth and creates jobs.
New Aerial Photos Highlight Progress
