Rock-bottom natural gas prices keep nuclear energy from being competitive

To all those who may be concerned that the catastrophic events at Japan's Fukushima Dai-ichi nuclear plant will derail the heralded renaissance of nuclear power in the U.S.: You can relax.

The reason is simple: There is no renaissance.

Not even Exelon Corp., the nation's biggest nuclear generation company, has been expecting a surge in orders or an appreciable increase in generating capacity.

The reason has little to do with the public's fear of nuclear meltdowns and radiation poisoning, and almost everything to do with economics. As John Rowe, Exelon's CEO, told an audience at a Washington think tank two weeks ago, you can build a new natural gas plant for 40 percent less than a new nuclear plant, and the price of its fuel is at rock bottom.

"Natural gas is queen," he said.

In recent years, nuclear energy has been promoted as a "green," or at least greenish, alternative to fossil-fueled generation. That's been a potent selling point as concern has mounted over the production of greenhouse gases. Nuclear power is burdened by its own environmental issues, including the dangers of radioactive release into the atmosphere, but the production of carbon dioxide isn't among them.

Yet the technology's potential as a weapon against global warming has been as oversold, just as its virtues as safe, clean and "too cheap to meter" were during its infancy in the 1950s. To realistically make a dent in climate change, nuclear plant construction would have to take off at such a rate that it would "pose serious concerns" for the availability of construction materials, properly trained builders and operating technicians, and safety and security oversight, as a report by the Council on Foreign Relations observed in 2007.

"For at least a couple of decades to come, nuclear will be very uncompetitive," the report's author, Charles D. Ferguson, told me recently. Ferguson is president of the Federation of American Scientists.

The ongoing disaster in Japan will exacerbate social concerns about nuclear waste disposal as well as concerns about the safety and security of existing plants. But those concerns have existed for years.

Talk of nuclear renaissance in the U.S. had been spurred by two developments. One was the dramatic improvement in the operating record of U.S. plants. In recent years the domestic nuclear industry had been operating at close to 90 percent of capacity, compared with the lousy 65 percent record it turned in during the 1970s. The change was the product partially of the industry's consolidation into a small number of specialty operators with nuclear expertise, and it tended to reduce the apparent cost of nuclear power to levels competitive with other sources.

But that also means that "people who advocate nuclear power have rose-colored glasses about its economics," said John E. Parsons of the Massachusetts Institute of Technology, the co-author of a 2009 update to a 2003 MIT report on the future of nuclear power.

Further encouragement came from the streamlining of U.S. licensing rules. The new procedure consolidates what formerly were separate construction and operating permits into one, removing the uncertainty that a utility might build an entire facility only to be denied permission to run it.

But no new plant has yet been approved under the new system, so plenty of uncertainty still exists. "An investor has to ask: 'Am I looking at a technology that works only when all the cards fall my way?' " Parsons said.

Despite expressions of support for nuclear power coming from political leaders, including President Barack Obama, who is offering loan guarantees for new reactors, nuclear energy can't develop in a policy vacuum. One of the dismal ironies of the American energy program is that many of the same politicians standing foursquare behind nuclear power are also sworn opponents of policies such as a carbon tax, which would make nukes more competitive by raising the price of fossil-based alternatives.

  5. 'Garbage juice' seen as threat to drinking water in Florida Panhandle county


    To Waste Management, the nation's largest handler of garbage, the liquid that winds up at the bottom of a landfill is called "leachate," and it can safely be disposed of in a well that's 4,200 feet deep.

    Three samples that were displayed by Jackson County NAACP President Ronstance Pittman at a public meeting on Waste Management's deep well injection proposal. The sample on the left is full of leachate from the Jackson County landfill, the stuff that would be injected into the well. The sample on the right shows leachate after it's been treated at a wastewater treatment plant. The one in the middle is tap water.
