NRC approves first new nuclear plant in a generation

(Reuters) - Regulators on Thursday approved plans to build the first new nuclear power plant in more than 30 years in spite of objections of the panel's chairman who cited safety concerns stemming from Japan's disastrous 2011 Fukushima disaster.

The Nuclear Regulatory Commission voted 4-1 to allow Atlanta-based Southern Co to build and operate two new nuclear power reactors at its existing Vogtle nuclear power plant in Georgia. The units will cost Southern and partners about $14 billion and enter service as soon as 2016 and 2017.

NRC Chairman Gregory Jaczko cast an extraordinary dissenting vote, citing the Fukushima nuclear disaster in Japan in March 2011 that spurred the NRC to review whether existing and new U.S. reactors could withstand natural disasters like earthquakes and floods.

"I cannot support issuing this license as if Fukushima never happened." Jaczko said. "I believe it requires some type of binding commitment that the Fukushima enhancements that are currently projected and currently planned to be made would be made before the operation of the facility."

The Obama administration has offered Southern and its partners $8.3 billion in federal loan guarantees as an incentive.

The new plant will use AP1000 reactors built by Westinghouse Electric, a standardized design approved by the NRC in December that will be the foundation for several other proposed nuclear plants. Westinghouse is majority owned by Japanese multinational Toshiba Corp.

SLOW NUCLEAR "RENAISSANCE"

There have been no nuclear power plants in the United States since the partial meltdown of the reactor core of the Three Mile Island plant in Pennsylvania in 1979, which caused construction costs for nuclear plants to skyrocket and stopped dozens of planned plants in their tracks.

Southern's Vogtle project is the first in a queue of permits filed by U.S. utilities, like Scana Corp, that were once predicted to usher in a "renaissance" of nuclear power. Nuclear power accounts for about 20 percent of U.S. electric generation.

Interest in building new nuclear plants had risen about a decade ago when natural gas prices were soaring and experts thought the U.S. Congress would place first-ever limits on emissions of carbon dioxide and other greenhouse gases.

But the case for widespread U.S. nuclear plant construction has eroded due to abundant natural gas supplies, slow electricity demand in a weak U.S. economy, lack of financing and uncertainty following the Fukushima disaster.

New nuclear plants are "more questionable because there are economic factors right now which favor gas-fueled power plants and the fact that the economy is only growing slowly means that nationally the need for new generation is lower than people were expecting in 2007," said Michael Golay, a professor at the Massachusetts Institute of Technology.

A 1,000-megawatt natural gas plant takes a few years to permit and build and costs up to $1 billion for the most efficient, combined-cycle model. A similar-sized nuclear reactor however could take five to 10 years to develop and build and cost in excess of $5 billion.

Industry experts say building interest is centered in Southeast states like Georgia, the Carolinas, Virginia, Alabama and Florida, where land is plentiful and a population shift from northern states has boosted electricity demand.
