WASHINGTON (AP) — U.S. regulators are considering a plan to build the nation's first nuclear power plant in a generation.
The Nuclear Regulatory Commission is set to vote Thursday on Southern Co.'s request to build two new reactors at Plant Vogtle in Georgia.
If approved, the $14 billion reactors could begin operating as soon as 2016 and 2017.
The NRC last approved construction of a nuclear plant in 1978, a year before a partial meltdown of the Three Mile Island nuclear plant in Pennsylvania raised fears of a radiation release and brought new reactor orders nearly to a halt.
The planned reactors are the remnants of a once-anticipated building boom that the power industry dubbed the "nuclear renaissance."
President Barack Obama and other proponents say greater use of nuclear power could cut the nation's reliance on fossil fuels and create energy without producing emissions blamed for global warming. A new government permitting process strongly encourages utilities to use pre-approved reactor designs rather than building custom models, a strategy intended to make construction easier and less expensive.
Obama has offered the Vogtle project $8.3 billion in federal loan guarantees as part of its pledge to expandnuclear power.
The once hoped-for boom has been plagued by a series of problems, from the prolonged economic downturn to the sharp drop in the price of natural gas, due in part to improved drilling techniques that have allowed energy companies to tap previously unavailable underground shale formations.
The nuclear disaster in Japan after an earthquake and tsunami last year also increased scrutiny of the industry and led to a series of recommendations by the NRC to improve safety at the nation's 104 nuclear reactors. The changes are intended to make the plants better prepared for incidents they were not initially designed to handle, such as prolonged power blackouts or damage to multiple reactors at the same time.
The agency also has proposed increased protection against earthquakes, floods and fires.
The Vogtle project is considered by many observers as a major test of whether the industry can build nuclearplants without the endemic delays and cost overruns that plagued earlier rounds of building decades ago.
The NRC approved a new reactor design for the Vogtle plant in December. Utility companies in Florida and the Carolinas also plan new reactors that use the same design by Westinghouse Electric Co.
South Carolina Electric & Gas Co. is also seeking permission to build two reactors at an existing plant in South Carolina.
