The second of two 300-ton “deaerator” components to be used in the construction of Plant Vogtle’s new reactors was barged up the Savannah River last week and then transported by truck to the Burke County nuclear site.
The 148-foot-long deaerator functions like a water purifier, eliminating dissolved gases such as carbon dioxide and oxygen from feedwater before it gets to a boiler and its pipeline. Deaeration prevents corrosion, helping to reduce plant maintenance and operating costs.
The steel component, manufactured in South Korea, arrived at the Port of Savannah aboard a cargo ship. It was loaded onto a barge and pushed up the river to Georgia Power’s Plant McIntosh.
From there, the deaerator and transporter were rolled off the barge together and pulled by truck for the two-day, 75-mile trip to the site, a Southern Nuclear spokesman said.
The Unit 3 deaerator arrived at the site in February.
The Vogtle expansion involves building two Westinghouse AP1000 reactors. The units are scheduled to begin commercial operation in the fourth quarters of 2017 and 2018, according to the most recent projections filed with the Georgia Public Service Commission.
