A major step toward building Plant Vogtle’s Unit 3 nuclear reactor was completed this week after workers spent 41 consecutive hours pouring concrete to form the unit’s 6-foot-thick foundation.

Workers pumped concrete through the night during a 41-hour pour to form the basemat foundation for Plant Vogtle's Unit 3 reactor.

The pouring of specially designed “nuclear concrete” was scheduled to occur last fall but was postponed to allow the U.S. Nuclear Regulatory Commission to rule on license amendments for the project’s design.

The concrete, known as basemat, will serve as the foundation for all of the nuclear island structures, including the containment vessel and the shield building. It covered an area about 250 feet long and 160 feet wide at its widest point.

A similar pour was completed Monday at South Carolina Electric & Gas Company’s V.C. Summer Plant, which – like Vogtle – is undergoing an expansion involving two Westinghouse AP1000 reactors.

The pours at both projects included efforts by an Augusta company – Ashmore Concrete Pumping Inc. – which was also helping pour the final roof sections this week at the mixed oxide fuel facility at Savannah River Site.

“It has been a great week for the nuclear construction field, and it has all happened in our area,” said the company’s president, Jerry Ashmore Jr.

Vogtle’s units 3 and 4 are expected to begin commercial operation during the fourth quarter of 2017 and 2018, respectively.

And another thought to this story is

Ashmore sent their concrete pump to Japan to help with the containment of the nuclear power plant there after the tsunami! Don't know all of the details but I am sure it took the Antonov Russian cargo jet to take it there!

Nuclear Concrete

Sounds very expensive!

lateness costs

The basemat pour was only a year late, so not much to crow about. How much did the delay cost the rate payers saddled with a pay-in-advance fees? Now, the more-complicated construction starts and watch closely to monitor further delays and cost increases with the $15-billion project. Georgians have assumed all risk and the company none, thanks to a radical Georgia legislature which doesn't believe in the free market.
