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.Get San Diego local news, weather forecasts, sports and lifestyle stories to your inbox.The cost of the third and fourth reactors was originally supposed to be $14 billion. The reactors are now supposed to cost more than $30 billion.
The latest set of delays at Unit 3 included a pipe part of a critical backup cooling system that was vibrating during startup testing. Construction workers had failed to install supports called for on blueprints. The company has also said it had to repair a slowly dripping valve and diagnose a problem involving water flow through reactor coolant pumps.
Georgia Power said Unit 3 would continue startup testing to show that its cooling system and steam supply system will work at the intense heat and pressure that a nuclear reactor creates. After that, operators are supposed to link the reactor to the electrical grid and gradually raise it to full power.
