Uranium Mining: The Dirty Side of "Clean" Nuclear Power

Those who tout the benefits of "clean" nuclear energy don't usually talk much at all about the dirty sides to this industry: uranium mining. As many of the most abundant sources of ore are on Native American lands, the pressure is on once again to open these lands to mining.

As reported by the Washington Post, Navajos in particular have borne the consequences of mining operations.

Like many Navajos who worked in the mines, Larry J. King didn't know then that there was anything dangerous about it. "We had no respirators; you'd have sweat running down your face with the uranium dust getting in your ears, nose and mouth," said King, who surveyed mine tunnels from 1975 to 1982. "You couldn't help but swallow it."

During mining's peak, from the early 1950s to the early 1980s, about 400 million pounds of uranium were extracted from the region. At the end of the boom, around 1984, the price of uranium languished below $10 a pound. Mines shut down, and the United States began importing nearly all of its uranium, with the bulk coming now from Canada, Russia and Australia. But by last summer, the price had rebounded to a record high of $136 a pound.

Though the mines created numerous jobs and substantial royalties for the Navajo and Laguna tribes, the decades of extraction took a heavy toll: lung cancer, kidney disease, birth defects and other ailments at notably high levels among miners and families who lived among piles of uranium tailings -- the ground-up waste from milling -- and even used the material to build their homes.

All but one of the major companies now seeking to mine in New Mexico are newcomers to the state and have promised to do a better job than their predecessors. In addition, pending state legislation would require them to deposit a small percentage of their profits in a "legacy fund" to clean up existing uranium contamination.

But King said, "I don't believe them one bit."

He blames his recent health problems on uranium. He remembers July 16, 1979, when more than 90 million gallons of uranium-contaminated water burst through the dam of a tailings holding pond and into the Puerco River running by his land. And he remembers seeing his cattle drop dead from, he thinks, drinking polluted mine runoff.


There is other dirt deeply embedded under this industry's fingernails as well, of course. Periodic tritium discharges from the stacks. Fish kills from overheated cooling water effluent. The carbon costs of the coal-fired plants that power the uranium processing facilities.

But, that's another story for another day.

Nuclear Power Information Tracker

The Union of Concerned Scientists, one of the best watchdog and energy advisory group around, offers a comprehensive online guide to the existing reactors in the U.S. The interactive map also provides some startling surprises, such as when you click on the button labeled "Show Inherently Safe Reactors" and get this popup:

An inherently safe reactor, in theory, would be designed, operated, and monitored in such a way that the reactor would never be damaged and, as a result, no radioactivity would ever be released to the environment. No such reactor currently exists. The risk from existing reactors is so real and so large that liability insurance from private companies is financially impossible, thereby requiring federal liability protection


The catalog of reactor problems, near misses, forced shutdowns, and spotty safety records is eye opening and a clear indication of the nature of the beast.

Bonnie Raitt and Others Expose Nuke Provisions

A little-known clause stuck in the pending Energy Bill tries to circumvent the market failures of nuclear power by foisting construction costs on the public. As described in a petition drive started by Working Assets, Act for Change, it's another attempt to derail open government in America, slipping drastic, costly meastures into legislation without public notice or disucssion. Working Assets stated:

The "new generation" nuclear plant now being built in Finland is already 18 months behind schedule and $900 million over budget. This is a design planned for our country. If construction begins here, tax and ratepayers will be stuck with the bill.

The Senate version of the Energy Bill could authorize the Department of Energy to provide virtually unlimited guarantees for backers of new reactors. The industry indicates it wants $25 billion in guarantees for 2008, and another $25 billion for 2009, with untold billions more to come after that.

The industry wants these subsidies because after fifty years, atomic power has been rejected by the marketplace. The first commercial nuclear reactor opened in 1957. But after fifty years of proven failure, Wall Street will not independently invest in more of them, and still no private insurance company will underwrite the possibility of a major reactor disaster.


Bonnie Raitt, Jackson Brown, Graham Nash, and Ben Harper speak out on this issue in the following clip:

From Oil Kings to Uranium Kings

Whether you have an energy economy geared to oil or hooked on uranium, as in France, as the commodity becomes scarce, the prices rise and fights often break out among those who want the remaining stores. This Le Monde editorial talks about the dynamics involved as France negotiates with Niger to ensure an ongoing supply of "yellow cake" to fuel its reactors.

Mr. Tandja has observed the price takeoff. A pound has gone from ten dollars three years ago to close to one hundred and fifty dollars on the international market (not counting long-term revisable contracts). And the increase should continue as needs grow and tensions over supplies appear. A windfall for Niger, which sees Chinese, Canadians, and Australians flooding in. World reserves are abundant, but exploration only resumed recently after twenty years of under-investment linked to attractive oil prices up to 2003 and to the rejection of nuclear power after the 1986 Chernobyl catastrophe. Demand from big American, German, French, Japanese, Chinese, and Russian electricity companies will grow as they build new reactors. With the exhaustion of military (especially Russian) stocks, recycled as fuel since the end of the Cold War to compensate for mining under-production, rationing looms.


Wind, solar, and geothermal are looking better all the time.

Japan Nuclear Plant Shutdown

Reliability has never been a strong suit of nuclear power plant operations, with safety problems, forced shutdowns, and similar difficulties plaguing the technology since its introduction. A recent quake in Japan, as reported by Reuters, put their largest plant out of commission.
And anyone who remembers the 2003 heat wave in Europe that took 35,000 lives might also remember that many of the nuclear power reactors in France went offline during much of that period because of cooling problems (sometimes produced by the rise in temperature of the water sourced for cooling intake). Similar problems occurred in Europe during July 2006.

Is it smart to invest in a technology that relies on absolute precision in controlling operational temperatures during a time when global warming is making that increasingly difficult? As the French reactor operators discovered, the approach doesn't work all that well.

Skewed Logic: Nuclear Power is the Solution

In an excellent piece in Orion Magazine, Reasons Not to Glow, Rebecca Solnit skewers the nuclear power cheerleaders who defy logic, reason, and common sense with their claims their nuclear power is the way to reverse climate change.
Nuclear power is clean, if you ignore uranium tailings and fuel processing and depleted uranium distributed with abandon in weaponry. Nuclear power is cheap, if you ignore the costs of decommisioning reactors after their 30- to 40-year lifespan and guarding the ruins for the next few centuries, as well as the accrued costs of the inevitable accidents. Nuclear power is the only way out of our situation, if you pretend that we can build them fast enough and that the remaining supplies of high-grade uranium ore won't run out in a couple of decades.
With a pen as sharp as a laser-tooled sword, Rebecca says:

If you’re not, at this point, chasing your poor formerly pronuclear companion down the hallway, mention that every stage of the nuclear fuel cycle is murderously filthy, imparting long-lasting contamination on an epic scale; that a certain degree of radioactive pollution is standard at each of these stages, but the accidents are now so many in number that they have to be factored in as part of the environmental cost; that the plants themselves generate lots of radioactive waste, which we still don’t know what to do with—because the stuff is deadly . . . anywhere . . . and almost forever. And no, tell them, this nuclear colonialism is not an acceptable sacrifice, since it is not one the power consumers themselves are making. It’s a sacrifice they’re imposing on people far away and others not yet born, a debt they’re racking up at the expense of people they will never meet.

Sure, you can say nuclear power is somewhat less carbon-intensive than burning fossil fuels for energy; beating your children to death with a club will prevent them from getting hit by a car. Ravaging the Earth by one irreparable means is not a sensible way to prevent it from being destroyed by another. There are alternatives. We should choose them and use them.

Nuclear Misinformation

The best insights about the future of nuclear power usually come from those in the thick of the debate. John Abbotts, a research scientist and member of the Hanford Task Force of Washington Physicians for Social Responsibility, offered these thoughts in an opinion piece published in the Seattle Times.
As their supporters have noted, atomic energy plants do not directly produce greenhouse gases during their operation. But they do produce prodigious amounts of radioactive waste, along with material that can be fashioned into atomic bombs.

Keeping the radioactive materials under control requires a complicated regulatory infrastructure; thus, it would be at least 10 years before new reactors could be designed, licensed, constructed and begin operation. By then, their capacity and energy demands could be a mismatch.

Not only would reactor plants take too long to have a significant impact on global warming, but they are expensive, multibillion-dollar facilities. It is faster and much more economical to save energy through efficiency improvements than to generate it through new power plants.

It's well worth reading the full column for the additional perspective.
