Global warming giving nuclear a good name

MIDDLETOWN, PENNSYLVANIA - The nation's worst nuclear power-plant accident was unfolding on Pennsylvania's Three Mile Island when an industry economist took the rostrum at a nearby business luncheon.

It did not go well.

Those in the standing-room-only crowd listened raptly to economist Doug Biden's thoughts about cheap, reliable nuclear power, but Biden could not calm their nerves or answer their pointed questions: Should they join the tens of thousands of people fleeing south-central Pennsylvania? Should they let their children drink locally produced milk?

Three decades later, fears of an atomic catastrophe have been largely supplanted by fears about global warming, easing nuclear energy into the same sentence as wind and solar power. Dogged by price spikes and an environmental assault on carbon-dioxide emissions, fossil fuels are the new clean-energy pariah.

"There's a lot of support for nuclear now, and most of that support is borne out of a concern for the desire to have emissions-free energy sources," said Biden, who still lobbies for power companies as the president of the Electric Power Generation Association in Pennsylvania.

Policymakers in numerous states are warming to nuclear power, even in states where the facilities are banned. Nuclear reactors generate one-fifth of the nation's power.

In light of last year's oil-price spikes, some see nuclear as a stable, homegrown energy source. Others see it as a way to meet carbon-reduction goals.

Public interest is emerging, too: A Gallup Poll released in recent days shows that 59 percent favor the use of nuclear power, the highest percentage since Gallup first asked the question in 1994.

If the U.S. nuclear industry is hitting a new high point, March 28 marked the anniversary of its low point. Thirty years ago, the malfunction of Three Mile Island's Unit 2 put its perils and shortcomings under the world's microscope.

No one was seriously injured in the accident, in which a small amount of radiation was released into the air above the Susquehanna River island, 12 miles south of Harrisburg. Studies of area residents have not conclusively linked higher rates of cancer to radiation exposure.

Since then, the U.S. Nuclear Regulatory Commission has not granted one license for a nuclear power plant. The industry says it has made major safety advances, but huge obstacles remain.

It takes years to license and build a reactor. Construction costs billions of dollars. The nation has no long-term storage site for the 2,000 tons of radioactive waste being produced annually by the 104 reactors operating in 31 states.

While some environmental groups grudgingly accept nuclear power as part of the energy landscape, others continue to oppose it. When waste costs and government subsidies are counted, nuclear is no more effective than a combination of efficiency measures, desert solar stations, wind power and geothermal energy, they say.

In March, President Barack Obama called for a cap on greenhouse-gas emissions that almost certainly would raise the cost to operate coal- and gas-fired plants. It was another arrow in the quiver of nuclear-power advocates who argue that there is no other reliable source of power that is free of greenhouse-gas emissions such as carbon dioxide.

In the past two years, 26 applications for new reactors have arrived at the Nuclear Regulatory Commission, which expects to issue a license no sooner than 2011. No such application was filed in the 28 years after the Third Mile Island accident.

In red states and blue states, public officials are paving the way for new reactors to move in. Even lawmakers in Kentucky and Oklahoma, which are rich in fossil fuels, are advancing bills that effectively would lift a moratorium on nuclear power.

"It makes sense to at least have other options out there," Oklahoma House Speaker Chris Benge said.

Republican Charlie Crist of Florida and Democrats Ed Rendell of Pennsylvania and Martin O'Malley of Maryland, governors who get high marks from environmental groups, all support proposals for new reactors in their states.

"By no means is (nuclear power) the sole answer to our energy problems, but I think it actually has a definitive place in the whole array of things we need to do to reach our goals of producing enough to meet demand," Rendell said.

In the past year, the Florida Public Service Commission approved four new reactors, including two at a proposed Progress Energy Inc. plant along central Florida's Gulf Coast.

Bill Johnson, chief executive of the Raleigh, N.C.-based utility, said the proposal met two important criteria for public acceptance: It dovetailed with Crist's anti-global-warming agenda and the desire for reasonably priced power.

Down the Susquehanna River from Rendell's office in the Pennsylvania Capitol, the destroyed Third Mile Island Unit 2 remains sealed.

Its core was shipped away years ago, and what is left inside the containment building remains highly radioactive.

Next to it is Unit 1, now owned by Exelon Corp. and still churning out electricity. Three Mile Island would even make a fine place to build another reactor — were it not for the memory of the 1979 accident.

"I think, politically, that would be difficult," Biden said.
