The US has approved construction of two atomic reactors in the country, making them the first to be built in America in more than three decades despite objections from the nation’s top nuclear regulator.
Commissioners of the Nuclear Regulatory Commission (NRC) voted 4-1 to approve the construction of two 1,100 megawatt Westinghouse-Toshiba AP1000 at power generator at Vogtle in Georgia. The site for the proposed plant already has two old reactors.
Only one member of the five-person NRC, Chairman Gregory Jaczko, dissented, citing safety concerns following a triple meltdown last year at the Fukushima Daiichi plant in Japan.
He argued that the new licences don’t go far enough in requiring the builders to incorporate lessons learnt from the Japanese nuclear disaster last year.
“In a 4-1 vote, the Commission found the staff’s review adequate to make the necessary regulatory safety and environmental findings, clearing the way for the NRC’s Office of New Reactors to issue the COLs (combined licences),” an official release said.
The Commission imposed a condition on the COLs requiring inspection and testing of squib valves, important components of the new reactors’ passive cooling system, it said.
The NRC certified Westinghouse’s amended AP1000 design on December 30, 2011. The AP1000 is an electric pressurised-water reactor that includes passive safety features that would cool down the reactor after an accident without the need for electricity or human intervention, it said.
The NRC decision in this regard is a significant one. Though the last new nuclear reactors came up in 1996; this is for the first time that NRC issued a licence to build a new reactor after 1978.
The US froze the construction of nuclear power plants after the partial core meltdown at Three Mile Island in 1979.
Congressman Joe Barton, Chairman Emeritus of the House Energy and Commerce Committee, applauded the NRC’s decision.
“For the first time since parachute pants and shoulder pads were all the rage, construction will soon begin on two new nuclear reactors,” he said.
