2297. Ecological Impacts of the Fukushima Daiichi Nuclear Meltdown 5 years Later

By Greenpeace-Japan, April 3, 2016

The report is based on a large body of independent scientific research in impacted areas in the Fukushima region, as well as investigations by Greenpeace radiation specialists over the past five years. It exposes deeply flawed assumptions by the International Atomic Energy Agency and the Abe government in terms of both decontamination and ecosystem risks. It further draws on research on the environmental impact of the 1986 Chernobyl nuclear catastrophe as an indication of the potential future for contaminated areas in Japan.

The environmental impacts of the Fukushima Daiichi nuclear disaster will last decades to centuries, due to man-made, long-lived radioactive elements are absorbed into the living tissues of plants and animals and being recycled through food webs, and carried downstream to the Pacific Ocean by typhoons, snowmelt, and flooding.

Greenpeace has conducted 25 radiological investigations in Fukushima since March 2011. In 2015, it focused on the contamination of forested mountains in Iitate district, northwest of the Fukushima Daiichi nuclear power plant. Both Greenpeace and independent research have shown the movement of radioactivity from contaminated mountain watersheds, which can then enter coastal ecosystems. The Abukuma, one of Japan’s largest rivers which flows largely through Fukushima prefecture, is projected to discharge 111 TBq of 137Cs and 44 TBq of 134Cs, in the 100 years after the accident.

2296. Trampling Science to Boost Nuclear Power

By Jim Naurkeckas, FAIR, April 21, 2016 

When the Washington Post and New York Times are making the same corporate-friendly point, it’s safe to assume that some PR agency somewhere is earning its substantial fees.

In this case, the subject is the need for nuclear power—and, for the Posteditorial board (4/18/16), for fracking as well. Standing in the way of this in the Post’s version is favorite target Bernie Sanders, while the Times business columnist Eduardo Porter (4/19/16)  blames the “scientific phobias and taboos” of “progressive environmentalists.”

“While campaigning in New York, Mr. Sanders has played up his opposition to nuclear power,” the Post editorialists wrote, citing his contention that the Indian River nuclear plant, 25 miles from Manhattan, is a “catastrophe waiting to happen.” Sanders’ “criticism came as little surprise,” the Post declared; “he had already promised to phase out nuclear power nationwide by steadily retiring existing reactors.”
“If we are serious about global warming, we will ignore Mr. Sanders’ sloganeering,” the paper urged. “Nuclear accounts for about a fifth of the country’s electricity, and it is practically emissions-free.”

In reality, nuclear power is not emissions-free; the process of mining and enriching uranium fuel, along with constructing nuclear plants, operating backup generators during reactor downtime, disposal of nuclear waste and eventual decommissioning of plants all contribute to greenhouse gas emissions. According to an analysis published by the journal Nature (9/24/08), nuclear power does produce 14 times less in greenhouse gas emissions than coal, and seven times less than natural gas—but twice as much as solar cells and seven times as much as onshore wind farms. For halting climate change, in other words, there are more serious options than nuclear.

The Post went on:

Shutting down that much clean electricity generation would put the country into a deep emissions hole. Mr. Sanders argues that he will invest heavily in renewables. Yet every dollar spent to replace one carbon-free source with another is a dollar that could have been spent replacing dangerous and dirty coal plants. Under Mr. Sanders’ vision, either the country would fail to maximize emissions cuts, or it would waste huge amounts of money unnecessarily replacing nuclear plants.

Sanders actually favors “a moratorium on nuclear power plant license renewals in the United States”—in other words, as the Post had earlier described it more accurately, “phas[ing] out nuclear power nationwide by steadily retiring existing reactors.” So it’s not a question of using money to replace a nuclear plant that could have gone to replacing a coal plant; the nuclear plants need to be replaced with something when they reach the end of their useful lives.

And if you put that money into renewables rather than into a new nuclear plant, you can reduce emissions more quickly. The investment bank Lazard analyzes the “levelized cost of energy”—the cost of building and operating an electrical plant per unit of electricity produced. In its latest report (11/15), the bank found that nuclear’s LCOE ranged from $97 to $136 per megawatt-hour, while wind costs between $32 and $77; utility-scale photovoltaic solar was priced between $50 to $70. Note that these costs for nuclear do not include the decommissioning of obsolete plants, which can add $1 billion–$4 billion to the lifetime cost, nor the cost of accidents like the Fukushima meltdown, which is expected to cost Japan some $300 billion (Renewable Energy World4/28/16).

The Post concluded that the best bet would be to put a tax on carbon, then “let the market find the fastest and most efficient road to slowing the warming of the planet.” The irony is that if you had a truly market-driven energy system, there’d be no need for a moratorium on nuclear licenses; if you didn’t have the Price-Anderson Act capping industry liability for nuclear accidents—requiring it to pay less than 2 cents on the dollar of the projected costs—it’s unlikely that another plant would ever be built.

Meanwhile, at the New York Times, Eduardo Porter was defending nuclear power—“the only technology with an established track record of generating electricity at scale while emitting virtually no greenhouse gases,” as we’ve debunked above—against an even scarier foe than Bernie Sanders: “the left” as a whole and its “scientific and technological taboos.”

Brought in as an expert witness to make this case is the internet entrepreneur who once complained that “anti-colonialism has been economically catastrophic for the Indian people for decades”:

“The left is turning anti-science,” Marc Andreessen, the creator of Netscapewho as a venture capitalist has become one of the most prominent thinkers of Silicon Valley, told me not long ago. He was reflecting broadly about science and technology. His concerns ranged from liberals’ fear of genetically modified organisms to their mistrust of technology’s displacement of workers in some industries. “San Francisco is an interesting case,” he noted. “The left has become reactionary.”

So far, the major achievement of GMO technology has been to boost 15-fold the use of Monsanto’s Roundup herbicide—which Monsanto’s seeds are engineered to be resistant to. Since the active ingredient in Roundup has been declared by the World Health Organization’s cancer researchers to be a probable human carcinogen, fear is not necessarily an unscientific reaction.

As for technology’s displacement of workers in San Francisco, that’s where one of Andreessen’s fellow tech entrepreneurs wrote an open letter complaining, “I shouldn’t have to see the pain, struggle and despair of homeless people to and from my way to work every day.” To be revolted by such attitudes is not “reactionary,” and you don’t need to be “anti-science” to be concerned that the soaring profits of the high-tech industry are pricing workers out of their homes.

But wrapping political and ethical choices in the mantle of “science” is what Porter’s column is all about—comparing to climate change denial the left’s failure to accept the “scientific consensus” on nuclear power, meaning that 65 percent of scientists favored building more nuclear plants in a Pew poll. The difference between an actual scientific consensus on the physical fact of global warming and a political preference expressed by two out of three scientists for a particular energy policy ought to be obvious; conflating the two is doing the opposite of what Porter claims to be advocating for, which is “somehow disassociating the scientific facts from deeply rooted preferences about the world we want to live in.”

The Times column offered some pre-emptive criticism of its own analysis: “Highlighting the left’s biases may seem like a pointless effort to apportion equal blame along ideological lines.” It’s not pointless at all, though: It’s a great way to sell pro-corporate policies under the guise of objective truth.

2295. Radioactive Wildlife Remind Us of Chernobyl

By Ron Borglio, The Atlantic, April 26, 2016
Radiation-caused mutations are widespread in wildlife

Radioactive, wild boar are invading towns in southern Germany. They travel in packs scavenging for food. They break through fences and roam the roads shutting down highway traffic. They take down a man in a wheelchair. Police scramble to restore order in urban centers. The boar are armed with a post-apocalyptic payload: Radioactive fallout from the 1986 Chernobyl nuclear disaster, which marks its thirtieth anniversary today. By foraging on radioactive plants, the animals embody the return of a disaster many seek to repress.

After the collapse and meltdown of a reactor at Chernobyl, over a hundred thousand people were evacuated from a 30-kilometer Exclusion Zone around the nuclear power plant. Residents exposed to the ensuing radiation suffered from leukemia, thyroid cancer, and other maladies. Some 4,000 people could die from illnesses related to the accident.

In the three decades since, a range of animals have taken up residence in the Exclusion Zone. They thrive in this occasionally mutant, non-human world where radiation remains 10 to 100 times higher than is safe for human occupancy. Rare species not seen in the region for hundreds of years have returned, including the Przewalski’s horse, the European bison, the lynx, and the Eurasian brown bear. Without fear of being hunted, the animals roam the forest and the ruins of cities in what has become an eerily post-human wildlife sanctuary.

As for the radioactive boar several hundred miles away in Germany, they become irradiated by eating plants downwind from the meltdown that contain residual traces of radioactivity—including truffles, tubers, and mushrooms that absorb high degrees of radioactive waste from the soil. Apart from anniversaries like this one, Chernobyl has faded from memory. But for the radioactive elements the disaster expelled, life has just begun. The disaster lives on, but invisibly.

Perhaps we should pay more heed to our fictions. After World War II, Godzilla, a fictional monster empowered by nuclear radiation, reminded Japan and the rest of the world that radioactive material is a beast more forceful and longer-living then humans can imagine. Allegorically, Godzilla made the otherwise invisible nuclear threat visible.
Other films followed suit. In the 1955 nuclear monster movie Them, an early atomic-bomb test in New Mexico mutates common ants into human-killing beasts. In it, the wise character Dr. Harold Metford (ominously played by the Miracle on 34th Street Santa Edmund Gwenn) observes, “We may be witnesses to a Biblical prophecy come true: ‘And there shall be destruction and darkness come upon creation and the beast shall reign over the earth.’” Mystery and ominousness ruled the day. “If these monsters got started as a result of the first atomic bomb in 1945,” Gunsmoke cowboy actor James Arness asks of Gween’s Metford at the film’s conclusion, “what about all the others that have been exploded since then?” To which Metford replies “Nobody knows. When Man entered the atomic age, he opened a door into a new world. What we’ll eventually find in that new world, nobody can predict.”

These accidental actors of ecological remembrance are not tricked out in Japanese monster costumes. There is no puppetry nor scale models. In fact, the Exclusion Zone and sanctuary around Chernobyl is also known by an almost existential title, the Zone of Alienation. And who is alienated if not we humans? First from a time outside of human time (the half-life of radioactive elements) and then from physical bodies that do not conform to planned technological progress. Even though they are more modest than our fictions imagined, creatures like boars have become the real Godzillas, invading our cities with their irradiated tusks to remind us of the limits of human control.

In 2010, a radioactive rabbit was found on the Hanford Nuclear Reservation in Washington state, the largest nuclear site in the Western Hemisphere. Hanford is the site of the first nuclear reactor and the facility that fed plutonium to the Fat Man Bomb dropped on Nagasaki, Japan. The bunny seems innocuous enough until one realizes that it, being a rabbit, breeds others—and with them more potential carriers of the radioactive conditions of their habitat. If there is one radioactive rabbit then there are other animals out there too. How many? As Dr. Metford says, nobody knows.

The Hanford reactor was put out of service in 1988 but left behind millions of tons of solid waste and hundreds of billions of gallons of liquid waste from its decades of producing plutonium. The waste is buried underground in pits and holding ponds where it has been forgotten. As the Department of Energy explains: “Depending on when the waste was buried, records about what was buried and where it was buried can be either very good, or in some cases, very bad.” As inhuman time moves onward, liquid waste has soaked into the soil. The membranes designed to separate nature and culture have worn down, and radioactive rabbits are the result.  

Thirty years after Chernobyl, the boar and bunnies wandering in its wake have brought us an anniversary gift. The Chernobyl boar aren’t just visitors from the past, it turns out. Thanks to the longevity of radiation, they are also visitors from the future. To take their lesson seriously would require accepting the repressed detritus of human progress, and incorporating that aftermath into the idea of human progress rather than believing that it remains safely buried, cordoned off, and forgotten.
