A Southern Co. executive laid the blame for some of the problems with two new reactors in Georgia at the feet of Louisiana welders in a story on Bloomberg.com.

Some components of the plant reactors were built at CB&I’s Lake Charles factory, which the company acquired along with Baton Rouge-based Shaw Group. But some of the welds on work there couldn’t meet stringent construction requirements and had to be redone.

Many of the welders at the Chicago Bridge & Iron factory in Lake Charles, where components of the reactors are built, were “used to work on oil rigs,” Joseph “Buzz” Miller, with Southern’s nuclear division, told Bloomberg News. The problems have since been addressed.

Miller’s comments were part of an analysis on what killed the country’s “climate-saving nuclear renaissance.”
