CAYCE — South Carolina Electric & Gas Company and its partners placed the first of three containment vessel rings June 2 for the Unit 2 nuclear reactor, one of the first nuclear units being built in the United States in 30 years.
Ring 1 was placed on top of the Unit 2 containment vessel bottom head. Now that the first ring is set, the remaining two rings will follow. All rings are fabricated with multiple levels of steel plates. The final component of the containment vessel will be the top head.
When complete, the containment vessel, which will house the reactor vessel, will weigh about 4,000 tons and stand more than 200 feet with a 130 foot-diameter.
About 2,500 Chicago Bridge & Iron and Westinghouse personnel and subcontractor personnel are currently involved in constructing two new reactors at V.C. Summer in Fairfield County, where Unit 1 has operated safely and reliably for more than 30 years.
The new nuclear project should peak at about 3,000-3,500 workers during certain points of construction. The two 1,117-megawatt AP1000 units will add 600 to 800 permanent jobs when operational. Once the two units are complete, SCE&G anticipates its generation mix will be about 30 percent nuclear, 30 percent natural gas, and 30 percent scrubbed coal, with the balance in hydro, solar and biomass.
