Seventy Years of Nuclear Fission: Short on Confidence; Long on Waste

On December 2, 1942, a small group of physicists under the direction of Enrico Fermi gathered on an old squash court beneath Alonzo Stagg Stadium on the Campus of the University of Chicago to make and witness history. Uranium pellets and graphite blocks had been stacked around cadmium-coated rods as part of an experiment crucial to the Manhattan Project–the program tasked with building an atom bomb for the allied forces in WWII. The experiment was successful, and for 28 minutes, the scientists and dignitaries present observed the world’s first manmade, self-sustaining nuclear fission reaction. They called it an atomic pile–Chicago Pile 1 (CP-1), to be exact–but what Fermi and his team had actually done was build the world’s first nuclear reactor.

The Manhattan Project’s goal was a bomb, but soon after the end of the war, scientists, politicians, the military and private industry looked for ways to harness the power of the atom for civilian use, or, perhaps more to the point, for commercial profit. Fifteen years to the day after CP-1 achieved criticality, President Dwight Eisenhower threw a ceremonial switch to start the reactor at Shippingport, PA, which was billed as the first full-scale nuclear power plant built expressly for civilian electrical generation.

Shippingport was, in reality, little more than a submarine engine on blocks, but the nuclear industry and its acolytes will say that it was the beginning of billions of kilowatts of power, promoted (without a hint of irony) as “clean, safe, and too cheap to meter.” It was also, however, the beginning of what is now a, shall we say, weightier legacy: 72,000 tons of nuclear waste.

Atoms for peace, problems forever

News of Fermi’s initial success was communicated by physicist Arthur Compton to the head of the National Defense Research Committee, James Conant, with artistically coded flair:

Compton: The Italian navigator has landed in the New World.
Conant: How were the natives?
Compton: Very friendly.

But soon after that initial success, CP-1 was disassembled and reassembled a short drive away, in Red Gate Woods. The optimism of the physicists notwithstanding, it was thought best to continue the experiments with better radiation shielding–and slightly removed from the center of a heavily populated campus. The move was perhaps the first necessitated by the uneasy relationship between fissile material and the health and safety of those around it, but if it was understood as a broader cautionary tale, no one let that get in the way of “progress.”

A stamp of approval: the US Postal Service commemorated Eisenhower's initiative in 1955.

By the time the Shippingport reactor went critical, North America already had a nuclear waste problem. The detritus from manufacturing atomic weapons was poisoning surrounding communities at several sites around the continent (not that most civilians knew it at the time). Meltdowns at Chalk River in Canada and the Experimental Breeder Reactor in Idaho had required fevered cleanups, the former of which included the help of a young Navy officer named Jimmy Carter. And the dangers of errant radioisotopes were increasing with the acceleration of above-ground atomic weapons testing. But as President Eisenhower extolled “Atoms for Peace,” and the US Atomic Energy Commission promoted civilian nuclear power at home and abroad, a plan to deal with the “spent fuel” (as used nuclear fuel rods are termed) and other highly radioactive leftovers was not part of the program (beyond, of course, extracting some of the plutonium produced by the fission reaction for bomb production, and the promise that the waste generated by US-built reactors overseas could at some point be marked “return to sender” and repatriated to the United States for disposal).

Attempts at what was called “reprocessing”–the re-refining of used uranium into new reactor fuel–quickly proved expensive, inefficient and dangerous, and created as much radioactive waste as it hoped to reuse. It also provided an obvious avenue for nuclear weapons proliferation because of the resulting production of plutonium. The threat of proliferation (made flesh by India’s test of an atomic bomb in 1976) led President Jimmy Carter to cancel the US reprocessing program in 1977. Attempts by the Department of Energy to push mixed-oxide (MOX) fuel fabrication (combining uranium and plutonium) over the last dozen years has not produced any results, either, despite over $5 billion in government investments.

In fact, there was no official federal policy for the management of used but still highly radioactive nuclear fuel until passage of The Nuclear Waste Policy Act of 1982. And while that law acknowledged the problem of thousands of tons of spent fuel accumulating at US nuclear plants, it didn’t exactly solve it. Instead, the NWPA started a generation of political horse trading, with goals and standards defined more by market exigencies than by science, that leaves America today with what amounts to over five-dozen nominally temporary repositories for high-level radioactive waste–and no defined plan to change that situation anytime soon.

The Thing That Couldn’t Die: Yucca Battle Continues in Congress and in the Courts

7:15 am in Uncategorized by Gregg Levine

In the 1958 cult horror classic The Thing That Couldn’t Die, a young lass out water-witching (of all things) discovers a curious and ancient box–one that, whether you follow the conventions of the genre or the entreaties of the film’s internal expert, should obviously remain closed.

But, as these things are wont to go, greed and ambition get the better of a few mere mortals, and the box is breached, revealing the intact–and living!–head of a sorcerer executed hundreds of years earlier. The wayward wizard then uses his telepathic powers to manipulate some of the more foolish, godless humans to unearth the rest of his body so that it might be reunited with the head and realize the full force of its destructive powers.

It is hard not to think of this black and white bubbe meise while reviewing the most recent chapters in the battle over the future of the partially excavated, purportedly moribund Yucca Mountain nuclear waste repository in southwestern Nevada.

As noted here last month, the life and death of the Yucca project was at the center of a public face off between President Obama and Senate Majority Leader Harry Reid, who just happens to hail from–and represent–the Silver State. Although the administration has sided with Reid on cancelling work on Yucca Mountain, Obama’s move to re-appoint Kristine Svinicki to another term on the Nuclear Regulatory Commission–over the vocal objections of the Majority Leader–registered with Yucca watchers like stirrings from the grave. Svinicki, after all, has been a staunch proponent of the Yucca project since she worked at the Department of Energy. . . writing the support documents for the Yucca nuclear waste repository. This week’s official re-nomination of Svinicki by the White House seems to say that rumors of Yucca’s demise are somewhat exaggerated.

Or at least that is what the nuclear industry and its army of lobbyists, captured regulators, and purchased politicians would have you believe.

As Republican members of Congress try to exert pressure on Reid and Senator Barbara Boxer (whose committee has jurisdiction over the NRC) to quickly confirm Svinicki, two states with heaping helpings of nuclear waste have gone to court to make sure that the Yucca repository is kept, if not on track, at least on life support.
