  • Jonathan Schell: ‘Our Illusion Is that We Can Control Nuclear Energy’

    In a SPIEGEL interview, peace activist and author Jonathan Schell discusses the lessons of the Fukushima disaster, mankind’s false impression that it can somehow safely produce electricity from the atom, and why he thinks the partial meltdown in Japan could mark a turning point for the world.

    SPIEGEL: Mr. Schell, what unsettled you the most about the Fukushima nuclear catastrophe?

    Schell: Clearly this whole accident just went completely off the charts of what had been prepared for. If you look at the manuals for dealing with nuclear safety accidents, you’re not going to find a section that says muster your military helicopters, dip buckets into the sea and then try as best you can to splash water onto the reactor and see if you can hit a spent fuel pool. There’s going to be no instruction saying, go and get your riot control trucks to spray the reactor, only to find that you’re driven back by radiation. The potential for total disaster was clearly demonstrated.

    SPIEGEL: But supporters of nuclear energy are already preparing a different narrative. They say that an old, outdated nuclear power plant was hit by a monster tsunami and an earthquake at the same time — and, yet, so far only a handful of people have been exposed to radioactive energy. Not a single person has died.

    Schell: Clearly it’s better than if you had had a massive Chernobyl-type release of energy. But I think that any reasonable analysis will show that this was not a power plant that was under control. The operators were thrown back on wild improvisation. The worst sort of disaster was a desperate mistake or two away. Through a bunch of workarounds and frantic fixes, technicians at Fukushima headed that off, but that was no sure thing. No one will be able honestly to portray this event as a model of nuclear safety. It would be like saying that the Cuban missile crisis showed the safety of nuclear arsenals.

    SPIEGEL: It is not just in Germany, but also in the United States and China that people are stockpiling supplies of iodine tablets. And shipments from Japan are supposed to be tested for radioactivity. Where does this profound fear of nuclear energy come from?

    Schell: In the public mind, nuclear power is associated with nuclear weapons. In both, a nuclear chain reaction is, in fact, the source of power. It’s true that you can’t have an atomic explosion in a nuclear power plant, but people are quite right to make that association. For example there is also the proliferation connection. In other words, the problem with the association of nuclear power with nuclear weapons goes beyond the escape of radiation and Chernobyl-type accidents. The third big challenge is, of course, the waste problem. You have to keep that waste underground for maybe a half-million years. So we’re acting in a kind of cosmic way in the terrestrial setting, even though we just don’t have the wisdom and staying power to do so.

    SPIEGEL: You say that dealing with nuclear energy is like gambling with “Mother Nature’s power.” Why is it so totally different from other sources of energy?

    Schell: Because it’s so colossally more powerful. Comparable energy can be found, at best, in the center of stars. It’s basically not found on earth naturally, and it’s only through our own scientific brilliance that we’ve been able to introduce it into the terrestrial setting. But, unfortunately, we’re not as advanced morally, practically and politically as we are scientifically, so we are not prepared to control this force properly. The most dangerous illusion we have concerning nuclear energy is that we can control it.

    SPIEGEL: Despite all these concerns, we have seen an emerging renaissance in nuclear energy in recent years.

    Schell: I don’t think there really was a nuclear renaissance. There was the phrase “nuclear renaissance,” but already in many parts of the world the financial aspects of nuclear power were not working out. The bankers were not stepping forward to finance new power plants. Insurance companies were reluctant to cover the risk.

    SPIEGEL: Many environmentalists are now even calling for an expansion of nuclear power — because they see it as the only way to limit climate change.

    Schell: I find their arguments weak. In the first place, there are about 450 nuclear power plants around the world. To make a serious dent in carbon emissions, you would have to double or triple that –and not only in countries as technically sophisticated as Japan. More importantly, I fear the attempted solution would be self-defeating in its own terms. Think how the high the cost will be if we pour our scarce resources into this faulty one and then there is a truly catastrophic accident down the road, and we were forced by this to liquidate the investment. This would be not only a disaster in its own right, but a disaster for the overall effort to head off global warming.

    SPIEGEL: German Chancellor Angela Merkel had always been a supporter of nuclear energy. Now she is talking about expediting Germany’s planned phase-out of nuclear power. Will Germany be able to succeed in eschewing nuclear power entirely?

    Schell: The anti-nuclear movement certainly has been stronger in Germany than in practically any other country, even before the Fukushima incident. I’d say it looks quite possible that Germany will go back to the phase-out policy, and that its nuclear power plants will be taken offline quickly. And I’d be surprised if Japan did not go in the same direction.

    SPIEGEL: Why don’t we see similar anti-nuclear protests in the United States?

    Schell: The whole nuclear industry has had a low profile in the United States, perhaps, in part, because we haven’t seen the construction of new power plants since the Three Mile Island accident in 1979.

    SPIEGEL: But President Barack Obama has now announced the construction of new nuclear power plants.

    Schell: … and people in the US don’t seem to be bothered by it so far. That’s been true, until now. New polls show that support for nuclear power has dropped sharply. Honestly, I don’t think Americans have been thinking about this issue very much. Now the Fukushima accident will concentrate people’s minds.

    SPIEGEL: Will Obama abandon his pro-nuclear energy policies?

    Schell: There’s a real chance that, in practice, he will back off — also for budgetary reasons. If you try to add in all kinds of new safety features, then you raise the price. The cost of building a nuclear power plant today already costs tens of billions of dollars.

    SPIEGEL: The greatest enthusiasm to be found anywhere once permeated the US shortly after the discovery of nuclear energy. During the 1950s, the Eisenhower administration enthusiastically promoted its “Atoms for Peace” program.

    Schell: That story is interesting because with President Dwight D. Eisenhower, we see the close connection at every stage of nuclear power with nuclear weapons. Eisenhower increased the US arsenal from around 1,400 to 20,000 nuclear weapons. But he also wanted an element of peace in his policy. This is where the “Atoms for Peace” program came in, whereby countries would be given technology to produce nuclear power, the “friendly atom,” in exchange for constraints on proliferation of nuclear weapons — the “destructive atom.” That rationale is still embodied today in the Nuclear Non-Proliferation Treaty.

    SPIEGEL: Obama has outlined his vision of a world without nuclear weapons. But the reaction to it has been lukewarm, even within his own team.

    Schell: Within the Obama administration, it seems to be the president himself — and possibly even the president alone — who really believes in this vision. But he has the public on his side. If you ask people if they would like to live in a world without nuclear weapons, a very high majority answer in the affirmative. On the other hand, there is a powerful bureaucratic infrastructure left in the Pentagon, in the State Department, in the Energy Department that is not ready to translate Obama’s vision into action and works to thwart it. He needs more supporters among his own officials.

    World Destruction Is Less Likely Today, But ‘Technically’ Possible

    SPIEGEL: Is a world without nuclear weapons even a realistic vision? With the technology already out there, wasn’t the genie permanently released from the bottle with Hiroshima in 1945?

    Schell: There will never be a world that is not nuclear capable. Once that knowledge was acquired, it could never be lost. So the art of living without nuclear weapons is an art of living without them, but with the knowledge of how to make them. The classic argument against a nuclear weapons-free world is that somebody will make use of that residual knowledge, build a nuclear weapon and start giving orders to a defenseless world. But what I point out is that other countries would also have that knowledge and they could, in very short order, be able to return to nuclear armament. Therefore, the imbalance is much more temporary than it first seems.

    SPIEGEL: Is the outlawing of nuclear weapons possible without also abolishing nuclear energy as well?

    Schell: A nuclear weapons-free world should be one in which nuclear technology is under the strictest possible control. But strict control of all nuclear technology is, of course, far more difficult as long as you continue to have nuclear energy production, as long as uranium continues to be enriched and as long plutonium is still being made somewhere.

    SPIEGEL: How serious do you think the current threat is of nuclear technology falling into the wrong hands?

    Schell: It is extremely real. The two most active hot spots for nuclear proliferation right now are Iran and North Korea. But you also have many other countries that are suddenly showing a renewed interest in nuclear power. The transfer of the technology in the Middle East, especially, is becoming a real danger. We may have fewer nuclear weapons, but we have more fingers on the button.

    SPIEGEL: Does that make the world today more dangerous than it was during the Cold War?

    Schell: No. I have too lively a memory of the Cuban missile crisis in the middle of the Cold War, which really looked like the potential end of the world. Regardless, it is true to say that the nature of the danger has changed.

    SPIEGEL: So the elimination of humanity through nuclear weapons is still a concrete possibility?

    Schell: Technically, the option is still there. What’s harder, though, is to frame scenarios in which all of the weapons would be fired simultaneously. Clearly, this is not as likely as it was during the Cold War. There are other colossal risks associated with lesser uses of nuclear weapons, though, ones that we are just becoming aware of. For instance, we have learned that the ecological perils of nuclear warfare can be triggered by much smaller numbers of weapons. There’s a new study showing that the use of just 100 or 150 nuclear weapons in a conflict between Pakistan and India would cause a nuclear winter through the burning of cities and the lofting of soot into the atmosphere. That would produce global famine.

    SPIEGEL: How great a threat do you think there is of nuclear weapons falling into the hands of terrorists?

    Schell: Over the long term, it’s clear that this danger is rising. It’s just in the nature of scientific knowledge and technology to become more and more available as time passes. The moment must come when it passes beyond the control of states alone and into the hands of lesser groupings.

    SPIEGEL: To what extent are nuclear power plants protected against terrorist attacks?

    Schell: So far, few adequate security precautions have been taken to mitigate the potential consequences. The nuclear energy industry has succeeded with its argument that such measures would simply be too costly.

    SPIEGEL: Does the example of the events in Japan show that human beings are incapable of learning from history? After all, the country is one that has experienced the horror of nuclear bombs first hand and nevertheless decided to rely on atomic energy.

    Schell: Kenzaburo Oe, the recipient of the Nobel Prize in Literature, said that going ahead with nuclear power in Japan is a betrayal of the victims of Hiroshima. But perhaps Fukushima will be a turning point — not just for Japan, but for the rest of the world as well.

    SPIEGEL: Mr. Schell, we thank you for this interview.

  • Mushroom Clouds and Everpresent Danger: Surviving Cameramen Recall Nuclear Test Shots

    By 1963, the United States had detonated more than 200 nuclear weapons in the atmosphere. Cameramen and photographers working for a secret special unit recorded the acts of destruction. Some of their sensational images have been declassified, and the last remaining eyewitnesses are now sharing their experiences.

    (-> VIDEO at SPIEGEL ONLINE)

    The atomic missile with the explosive power of 1.5 kilotons of TNT detonated precisely above the heads of the five United States Air Force scientists. At first the men felt only the heat from the explosion. But then the blast wave forced them to their knees.

    George Yoshitake’s camera was clicking the entire time.

    At 7 a.m. on July 19, 1957, the cameraman was standing with a small group of nuclear scientists on the Yucca Flat test site in the state of Nevada. A fighter jet had fired the missile at an altitude of five kilometers (3.1 miles), which was considered a safe distance from the ground. “I was busy behind the cameras,” Yoshitake recalls. “Then I could see the flash go off out of the corner of my eye.” He looked up. “There was this huge, doughnut-shaped cloud up in the sky where the blast when off.”

    The only thing protecting him from the bomb’s fallout was his baseball cap.

    Yoshitake is one of the few people who have stood directly underneath an exploding atom bomb and survived. The American was one of about 40 photographers and cameramen in the 1352nd Photographic Group of the US Air Force. Their mission was top secret. Today Yoshitake, now 82, can finally talk openly about his experiences.

    The special unit’s job was as fascinating as it was dangerous. To film and photograph the American nuclear tests in the Nevada desert and in the South Pacific, the foolhardy men had to place themselves within only a few kilometers of the centers of the explosions.

    Images the Public Never Saw

    Between 1947 and 1969, the material was edited to make more than 6,500 motion pictures in a secret film studio in the Hollywood Hills neighborhood of Los Angeles, just a few kilometers from the bright lights of Sunset Boulevard. The studio on Wonderland Avenue was called the Lookout Mountain Air Force Station. Using special film and high-speed cameras, cameramen and photographers used the film and photographic footage to artfully produce motion pictures and still photographs.

    “Those men are great guys; they documented a period of time that was both unique and hopefully will never be repeated,” says US documentary filmmaker Peter Kuran, 54, who is working on the story of the “atomic filmmakers.” Kuran wants to preserve the historic film material for posterity. “The photos are the icons of an era,” he says.

    At the height of the Cold War, the superpowers embarked on a spectacular race to develop nuclear weapons. It was accompanied by an unparalleled propaganda war that involved large numbers of tests. By the time the international Treaty banning Nuclear Weapon Tests In The Atmosphere, In Outer Space And Under Water, or Nuclear Test Ban Treaty (NTBT), was signed in 1963, the Americans alone had already detonated more than 200 atomic and hydrogen bombs in the atmosphere. The goal, from the very beginning, was to create impressive images to convince politicians to approve ever-growing military budgets.

    But the public never saw most of the images. “The work these people did was so secretive that nobody even knew who they were for a long time,” says Kuran. It wasn’t until the mid-1990s that the first photographs and films were declassified, thanks to the documentary filmmaker’s relentless efforts. Kuran traveled throughout the United States, searched through archives and urged the US Department of Energy to release the films and photographs.

    Copies of the material are now stored in gray cardboard boxes in the basement of Kuran’s house in Vancouver, Washington. Nuclear weapons have become a central focus of his life. “When I was 15, I visited Japan with a YMCA (youth) group,” he says. “We happened to be in Hiroshima on the anniversary of the bombing and I saw a film about the destruction of the city. I was the only American in a crowded room full of Japanese. Everyone was looking at me.”

    Kuran felt horrified and ashamed. Initially, he embarked on a career as a developer of special effects for productions like director George Lucas’s “Star Wars” movies. But he couldn’t forget his experience in Japan. More than three decades later, he coincidentally came into contact with those chroniclers of the nuclear tests who were still alive. The nuclear filmmakers were grateful for the attention. “We’re finally getting recognized for some of the work we did,” says Yoshitake. “It was liberating to be able to talk about it.”

    The cameraman now lives in Lompoc, California, about a three-hour drive north of Los Angeles. He is one of the last surviving members of the photographers’ unit. Most of the others died long ago, many of cancer. Yoshitake says he is “more in contact with the widows.”

    From 1955 to 1963, Yoshitake worked for the nuclear weapons test program. “I filmed about 30 explosions,” he reports. “The amazing ones, the most spectacular ones were the hydrogen bombs in the Pacific.” The bombs were usually detonated early in the morning, before dawn, says Yoshitake. “They told us to look away at the initial blast,” he recalls. “For several minutes after the blast, you could see this eerie ultraviolet glow high up in the sky. And I thought that was so spectacular, so meaningful.”

    The images from the Pacific seem almost magical, including the photos of the seven-kilometer fireball created by “Shrimp,” the most powerful bomb the United States ever detonated. On March 1, 1954, a 15-megaton bomb, part of an operation called Castle Bravo, exploded over the Bikini atoll. The destructive power unleashed by the explosion was more than twice as high as the experts had predicted and tore a crater two kilometers in diameter into the island. Within a few minutes, a mushroom cloud rose 40 kilometers into the sky. The entire archipelago was contaminated with radiation and remains uninhabited to this day.

    The cameramen came within about 30 kilometers of the artificial suns in the South Pacific. In the Nevada desert, Yoshitake and his colleagues even came within about eight kilometers of the fireballs. “We could see how the shockwave came rolling across the valley floor,” says Yoshitake. “We hung onto our cameras so we wouldn’t fall over.”

    A few seconds after the explosions, the men also felt the heat from the bombs. The cameraman took it all in stride. “We were young. For me it was a just a job at the time. Only now do I realize how dangerous the work was,” he says.

    For Yoshitake, the work only became unpleasant when it was time to document the effects of the bombs. He shudders when he remembers a test performed in June 1957 under the code name “Priscilla.” Only 30 minutes after the detonation, he had to photograph monkeys, sheep and pigs that had been placed in close proximity to the blast site. “A few of the animals were still alive,” says Yoshitake. The skin on the pigs was charred black, he says, while the eyes of the monkeys had been taped open so that scientists could study the effect of the flash of light on the retina. “The animals were squealing, crying. It smelled of burned flesh. It was just terrible.”

    At least the cameramen wore protective suits on those missions into the center of destruction. But when they confronted the nuclear blasts from afar, they were wearing nothing but shorts and T-shirts. “We had dosimeters that measured our radiation load. That was it,” says Yoshitake’s former colleague, Ken Hackman, 72, who spent months in the Pacific to photograph the tests. He remembers how reckless the military’s behavior was at the time: “After the detonation, B-57 bombers would always fly directly through the mushroom cloud to collect samples. After the planes had landed again, they were decontaminated by men who were only wearing rubber boots as protection.”

    To this day, Hackman sees the bomb tests through the eyes of a photographer. The flash from a nuclear weapon is 10 times as bright as the sun, he says. The photographers had to wear heavily tinted special glasses to prevent burning of the retina. “Everything turns a bright white, and there’s no color at all anymore,” says Hackman. “Once the initial brightness is away, it really is very beautiful to look at.” He has vivid memories of a working trip to Hawaii, where he stood on a volcano and photographed the colorful aurora of an exploding hydrogen bomb. The play of lights in the sky was caused by the strong magnetic field generated by the detonation.

    Capturing the Blast

    The photographers tried out almost every camera model available at the time and tested completely new photographic techniques. Automatic cameras were placed a few hundred meters from the point of explosion, with thick lead shields protecting the film material from gamma radiation. The most advanced film cameras of the day were capable of recording 15 million images per second. The filmmakers even experimented with 3-D photography.

    The US company EG&G was the main source of the inventions. One of the founders of EG&G was Harold Edgerton, who later became world-famous for his photographs of bursting drops of milk. For the nuclear weapons test program, the engineers at EG&G developed a special film with three coatings, each with a different level of sensitivity. The so-called XR film made it possible to photograph the detonations with a single high-speed camera, despite tremendous fluctuations in light intensity.

    The XR film enabled the photographers to capture the power of the weapons in brilliant orange, yellow and red tones, creating highly alienating images of “psychedelic quality,” says Kuran. The US space agency, NASA, later used the technology to photograph its moon missions.

    Eventually the EG&G engineers even managed to capture the first microseconds of atomic explosions on film, using the “Rapatronic,” a camera developed specifically for this purpose. Because a mechanical shutter would have been much too slow, the device had an electronic “light valve” made of polarized special glass, which could be rendered translucent by means of an electric pulse.

    The engineers placed up to 16 of these high-tech cameras near the point of explosion, which allowed them to capture the birth of the atomic hellfire, so to speak. The bubble-like nuclear blast images almost look like living creatures in the photos. The billowing formations of heat and radiation, at temperatures of up to 10 million degrees Celsius, resemble oddly shaped amoeba.

    The Dichotemy Between Destruction and Beauty

    Most of these images are still under lock and key today. Only military physicists are permitted to analyze the images for the purpose of improving the designs of bombs. The US government is still hesitant to release the photos and films completely. But it is critical, says Kuran, that the material be processed and digitized, “before it turns to dust.”

    He has already assembled five documentaries from the film and photographic footage, which he distributes through his website. A sixth film, about the neutron bomb, is in the works. “My goal is to present as realistic an impression as possible of the power of these weapons, but I’m also fascinated by this bizarre dichotemy, how destructive they were and how beautiful they were,” says Kuran.

    The filmmaker hopes that his work will serve as a warning against nuclear testing. But the work has also taught him a surprising lesson. “Personally, I have less fear of nuclear weapons than I used to have,” says the documentary filmmaker. “Now I know that if somebody exploded a big hydrogen bomb 30 kilometers away from me, chances are I will probably survive.”
