Construction on the site started two years ago with about $4 billion already spent.
Chu told reporters Wednesday after touring the construction site at Plant Vogtle that completing the $14 billion project on time and within its budget would tell other power companies that new nuclear plants make "a good investment."
Chu's visit to east Georgia comes a week after the Nuclear Regulatory Commission approved a license for the Southern Co. to build a third and fourth reactor at Plant Vogtle. They will be the first commercial reactors built in the U.S. in more than 30 years.
