Deep Time, Short Sight

Bracing for Yucca Mountain's Nuclear Forever

In 1945, as the first atomic bomb was detonated in the New Mexico desert, one of its creators, physicist J. Robert Oppenheimer, recalled a line from Hindu scripture: "Now I am become Death, the destroyer of worlds." This being America, though, someone smelled a profit behind this almost biblical source of power—nine years later, the Atomic Energy Act allowed private companies to build commercial nuclear reactors, with the promise of "energy too cheap to meter." But the bill for three generations' worth of nuclear power is now coming due. The Department of Energy is proposing to transport highly radioactive material from all over America to a nuclear waste dump inside Yucca Mountain, Nevada. Governor Kenny Guinn estimates construction of the facility will eventually cost more than $60 billion.

He and most other Nevadans (with the exception of some local brothel owners, who predict a free-spending clientele among the army of workers expected at the site) are not happy that their state, already host to the radioactive leavings of decades of nuclear weapons tests, would receive 6 billion curies more. (By comparison, the accident at Three Mile Island released 15 curies.)

In an interview, Steven Frishman, a geologist with Nevada's Nuclear Waste Task Force, talks about "downwinders," people who suffered deadly, long-term effects from the weapons testing, and how the federal government "knew it was dangerous and they weren't telling people." Now, he says, that same government, along with the nuclear industry, is "spinning the site," using "extraordinary levels of optimism and trying to convince people that it's safe because they have a political need to do it, not because it's actually a safe thing to be doing."

The problem? The waste is so lethal that by law it must be completely isolated for a minimum of 10,000 years. But many scientists (including a panel from the National Academy) dismiss that time span as a bureaucratic convenience. Others point out that much of the waste (mostly spent fuel rods from commercial and military reactors) will contain uranium, plutonium, and myriad other "iums" that will be dangerous for hundreds of thousands to millions of years. Nevada's concern is that the site is not sound enough geologically to keep the waste from eventually getting into the groundwater, air, and food chain. DOE's own best case shows no violation of current radiation dose standards for roughly 100,000 years, but, as Governor Guinn's recent letter to Congress points out, DOE's computer models "have an uncertainty factor of 10,000."

Still, the Yucca Mountain site is heading for a final, too-close-to-call vote in the Senate, and if it is approved, the maw of bureaucracy must be served. The Environmental Protection Agency has decreed that some kind of marker be erected to deter human beings from entering, drilling, digging, mining, or doing anything that would disturb the site or release its contents into the environment for the 10-millennium regulatory period.

So artists, architects, and engineers must grapple with a time span at the outer limits of cultural imagination, a period that must take into account climatic change (will the brutal desert currently surrounding Yucca become wetter in a few thousand years?) and geology (there have been 600 earthquakes of 2.5 or greater magnitude in the area since 1982). And then there is humanity: As Frederick Newmeyer, president of the Linguistic Society of America, points out, any language becomes "unintelligible to the descendants of the speakers after the passage of between 500 and 1000 years." (Read any Chaucer lately?) So how do we warn away people whose language, society, and beliefs we'll never know, who may have undergone revolutions, disasters, wars, or epidemics right out of The Stand?

The challenge of communicating danger over vast reaches of time was taken up by an exhibition earlier this year at the University of Nevada, Las Vegas, entitled "Universal Warning Sign: Yucca Mountain." The organizer of the show, Joshua Abbey, wanted to use art to educate the public about the long-term hazards of the proposed dump. He received entries from around the world, many of which used the trefoil symbol for radiation, designed in 1946. But the meanings of symbols change drastically over time and from culture to culture. The swastika, long revered in many parts of the world as a symbol of good fortune, is metaphorically radioactive in others—it will get you jail time in Germany.

The winning entry illuminates the problem of communicating tens, hundreds, and thousands of generations into the future. Ashok Sukumaran proposes to seed all of Yucca Mountain with self-replicating, genetically engineered, cobalt-blue cactuses, using this unnatural contrast against the ochre of the desert as a living warning. Clearly, though, this painted desert would be hauntingly beautiful and alluring, and might draw people rather than repel them. And there's the rub: Art and architecture act as our highest expressions of humanity, not as shouts of danger. Libby Lumpkin, the founding curator of the art collection in Steve Wynn's Bellagio Hotel, said one of the reasons she was interested in being a juror was "it was a show that no one could succeed at."

Not that the government hasn't been on the case. The template for the eventual marker at Yucca Mountain was conceived in the early '90s for the Waste Isolation Pilot Plant near Carlsbad, New Mexico, the eternal (or so the DOE hopes) subterranean home of the detritus of the nuclear arms race. Among other things interred there are "contaminated laboratory piping, and booties and masks," says Michael Brill, an architectural theorist and professor at SUNY Buffalo. He led one of two teams of linguists, artists, engineers, archaeologists, and other experts, who were charged by Sandia National Laboratories to design a method of keeping future Indiana Joneses out of this real temple of doom. "Passive Institutional Controls," meaning monuments impervious to harsh climate and sandblasting winds, are mandated, because even the federal government has to acknowledge it might not be around in a few hundred years, never mind millennia hence.
