Georgia nuclear plant begins splitting atoms for first time

A nuclear power plant in Georgia has begun splitting atoms in one of its two new reactors, Georgia Power said Monday, a key step toward reaching commercial operation at the first new nuclear reactors built from scratch in decades in the United States.

The unit of Atlanta-based Southern Co. said operators reached self-sustaining nuclear fission inside the reactor at Plant Vogtle, southeast of Augusta. That makes the intense heat that will be used to produce steam and spin turbines to generate electricity.

A third and a fourth reactor were approved for construction at Vogtle by the Georgia Public Service Commission in 2009, and the third reactor was supposed to start generating power in 2016. The company now says Unit 3 could begin commercial operation in May or June.
