fukushima updates

may 18

SEOUL — Japanese playwright Oriza Hirata, who serves as a special adviser to the Cabinet, claimed in a recent lecture given in Seoul that the dumping of low-level radioactive water into the Pacific Ocean followed a "strong request" from the United States, a person who attended the lecture said Wednesday. The release of the water from the Fukushima No. 1 nuclear power plant last month generated anxiety about the possible spread of radioactive contamination from the seaside power station. The Japanese government had apparently given its permission for the release of the water after receiving a report from plant operator Tokyo Electric Power Co. Hirata's remarks, made Tuesday, that the release was not carried out based on Tokyo's independent judgment but rather on a request from Washington is likely to ignite a debate. South Korea and other neighboring countries have protested the lack of prior notification of the discharge...While acknowledging that the release of the water caused concern in South Korea, he said the thousands of tons of water were not highly radioactive.

"Only the mass media can put the kind of pressure on TEPCO and the Japanese government to bring about major change. This will cost at least 10 billion dollars if not 20-30 billion to clean up. It will take at least 10 years if not 20 and roughly 10,000 people working on the cleanup. The nuclear business is global. This needs an international effort to clean up Fukushima."

Tokyo Electric Power Co. (TEPCO) admitted for the first time on May 15 that most of the fuel in one of its nuclear reactors at the Fukushima No. 1 Nuclear Power Plant had melted only about 16 hours after the March 11 earthquake struck a wide swath of northeastern Japan and triggered a devastating tsunami...

Who Will Take the Radioactive Rods From Fukushima?

The decommissioning of the Fukushima 1 nuclear plant is delayed by a single problem: Where to dispose of the uranium fuel rods? Many of those rods are extremely radioactive and partially melted, and some contain highly lethal plutonium.

Besides the fissile fuel inside the plant's six reactors, more than 7 tons of spent rods have to be removed to a permanent storage site before workers can bury the Fukushima facility under concrete. The rods cannot be permanently stored in Japan because the country's new waste storage centers on the northeast tip of Honshu are built on unsuitable land. The floors of the Rokkasho reprocessing facility and Mutsu storage unit are cracked from uneven sinking into the boggy soil.

Entombment of the rods inside the Fukushima 1 reactors carries enormous risks because the footing of landfill cannot support the weight of the fuel rods in addition to the reactors and cooling water inside the planned concrete containment walls. The less reactive spent fuel would have to be kept inside air-cooled dry casks. The powerful earthquakes that frequently strike the Tohoku region will eventually undermine the foundations, causing radioactive wastewater to pour unstoppably into the Pacific Ocean. The rods must therefore go to another country.
American Bad Faith

Under the Non-Proliferation Treaty (NPT), signed by Japan in 1970, Washington's negotiators stipulated that used nuclear fuel from Japanese reactors must by law be shipped to the United States for storage or reprocessing to prevent the development of an atomic bomb. Washington has been unable to fulfill its treaty obligations to Tokyo due to the public outcry against the proposed Yucca Mountain storage facility near Las Vegas.

A panel convened by the Obama administration has just recommended the set up of a network of storage sites across the United States, a controversy certain to revive the anti-nuclear sentiments during the upcoming election campaign. The American nuclear industry has its own stockpile of more than 60,000 tons of spent fuel - not counting waste from reactors used for military and research purposes - leaving no space for Fukushima's rods inside the Nevada disposal site, if indeed it is ever opened.
To Continental Asia
The Tokyo Electric Power Company (Tepco) has allocated 1 trillion yen ($12 billion) in funds for nuclear waste disposal. Areva, the French nuclear monopoly, has teamed up with Tepco to find an overseas storage site. So far, the Tepco-Areva team have quietly contacted three Asian countries - Kazakhstan, China and Mongolia -- to set up a center for "reprocessing", a euphemism for nuclear dump site.

Among the threesome, China was the top choice for the Japanese nuclear establishment, which has confidence in Beijing's ability to safeguard nuclear secrets from its citizenry and even from the top leaders. Japan's space agency, which keeps 24-hour satellite observation over every nuclear-related facility in China, possesses the entire record of radiation leaks there. Since Beijing withholds this sort of data from the public, the Japanese side felt it had the necessary leverage in talks with Chinese nuclear officials.

Though the nuclear-sector bureaucrats were initially eager to receive bundles of yen, the proposal was blown away by the salt craze that swept over China. Within a couple of weeks of the Fukushima meltdowns, millions of shoppers emptied supermarket shelves on rumors that iodized salt could prevent radiation-caused thyroid cancer. The Chinese public is rightfully fearful of health-related scandals after discoveries of melamine in milk, growth hormones in pork, pesticides in vegetables, antibiotics in fish and now radioactive fallout over farmland.

A nuclear disposal deal would require trucks loaded with radioactive cargo to roll through a densely populated port, perhaps Tianjin or Ningbo, in the dead of night. There is no way that secret shipments wouldn't be spotted by locals with smart phones, triggering a mass exodus from every city, town and village along the route to the dumping grounds in China's far west. Thus, the skittishness of the ordinary Chinese citizen knocked out the easiest of nefarious plans.
Principle of Industrial Recovery
A more logical choice for overseas storage is in the sparsely populated countries that supply uranium ore to Japan, particularly Australia and Canada. As exporters of uranium, Canberra and Ottawa are ultimately responsible for storage of the nuclear waste under the legal principle of industrial recovery.

The practice of industrial recovery is already well-established in the consumer electronics and household appliances sectors where manufacturers are required by an increasing number of countries to take back and recycle used television sets, computers and refrigerators.

Under the principle, uranium mining giants like Rio Tinto and CAMECO would be required to take back depleted uranium. The cost of waste storage would then be factored into the export price for uranium ore. The added cost is passed along to utility companies and ultimately the consumer through a higher electricity rate. If the market refuses to bear the higher price for uranium as compared with other fuels, then nuclear power will go the way of the steam engine.

Australian and Canadian politicians are bound to opportunistically oppose the return of depleted uranium since any shipments from Fukushima would be met by a massive turnout of "not-in-my-backyard" protesters. The only way for Tokyo to convince the local politicos to go along quietly is by threatening to publish an online list of the bribe-takers in parliament who had earlier backed uranium mining on behalf of the Japanese interests.

Nuclear's Cost-Efficiency

The question then arise whether nuclear power, when long-term storage fees are included, is competitive with investment in renewable energy such as wind, solar, hydro and tidal resources. Renewable energy probably has the edge since they don't create waste. Natural gas remains the undisputed price beater wherever it is available in abundance. In a free market without hidden subsidies, nuclear is probably doomed.

In a lapse of professionalism, the International Atomic Energy Commission (IAEA) has never seriously addressed nuclear-waste disposal as an industrywide issue. Based on the ration of spent rods to reactor fuel inside U.S. nuclear facilities, there are close to 200,000 metric tons of high-level nuclear waste at the 453 civilian nuclear-energy plants worldwide. Yet not a single permanent storage site has ever been opened anywhere.

The Fukushima 1 dilemma shows that the issues of cost-efficiency and technological viability can no longer be deferred or ignored. Ratings agencies report that Tepco's outstanding debt has soared beyond $90 billion, meaning that it cannot cover future costs of storing spent rods from its Kashiwazaki and Fukushima 2 nuclear plants. The Japanese government's debt has soared to 200 percent of GDP. Neither entity can afford the rising cost of nuclear power.

The inability of Tepco or the government to pay for nuclear waste disposal puts the financial liability squarely on its partner companies and suppliers, including GE, Toshiba, Hitachi, Kajima Construction and especially the sources of the uranium, CAMECO and Rio Tinto and the governments of Canada and Australia. A fundamental rule of both capitalism and civil law is that somebody has to pay.
Last Stop

Since Australia and Canada aren't in any hurry to take back the radioactive leftovers, that leaves Japan and treaty-partner United States with only one option for quick disposal- Mongolia.

Ulan Bator accepts open-pit mining for coal and copper, which are nothing but gigantic toxic sites, so why not take the melted-down nuclear rods? Its GDP, ranked 136 among the world's economies, is estimated to be $5.8 billion in 2010. Thus, $12 billion is an unimaginable sum for one more hole in the ground.

Not that Mongolia would get the entirety of the budget, since the nuclear cargo would have to transit through the Russian Far East. Unlike the health-conscious Chinese, the population of Nakhodka or Vladivostok are used to playing fast-and-loose with radioactive materials and vodka.

Even if the mafia that runs the Russian transport industry were to demand a disproportionate cut, Mongolia's 3 million inhabitants would be overjoyed at gaining about $2,000 each, more than the average annual income, that is if the money is divided evenly after the costs of building the dump.

Realistically, the Mongolian people are unlikely to receive a penny, since the money will go into a trust fund for maintenance costs. That's because $12 billion spread over the half-life of uranium - 700 million years - is equivalent to $17 in annual rent. That doesn't even cover kibble bits for the watchdog on duty, much less the cooling system. Not that anyone will be counting since by the time uranium decays to a safe level, fossils will be the sole remnant of human life on Earth.

Illusory, shortsighted greed will surely triumph in Mongolia, and that leaves a question of moral accountability for the rest of us. Will the world community feel remorse for dumping its nuclear mess onto an ancient culture that invented boiled mutton, fermented mare's milk and Genghis Khan? For guilt-ridden diplomats from Tokyo and Washington wheedling the dirty deal in Ulan Bator, here's the rebuttal: Did the national hero, the Great Khan, ever shed any tears or feel pangs of guilt? There's no need for soul-searching. A solution is at hand.

...highly radioactive substances were detected in parts of Tokyo. Japan's Asahi Shimbun reports about 3,200 and nearly 2-thousand becquerels of radioactive cesium per kilogram were found in the soil of Tokyo districts of Koto and Chiyoda, respectively, from testing conducted between April 10th and the 20th. This amount is higher than what was found in the prefectures near the Fukushima plant and experts warn that other areas may be subject to radiation contamination as clusters of clouds containing radioactive material remain in the atmosphere...(Arirang TV Korea)

TEPCO concealed radiation data before explosion at No. 3 reactor

Tokyo Electric Power Co. concealed data showing spikes in radiation levels at the Fukushima No. 1 nuclear power plant in March, one day before a hydrogen explosion injured seven workers.

The Asahi Shimbun obtained a 100-page internal TEPCO report containing minute-to-minute data on radiation levels at the plant as well as pressure and water levels inside the No. 3 reactor from March 11 to April 30.

The data has never been released by the company that operates the stricken plant.

The unpublished information shows that at 1:17 p.m. on March 13, 300 millisieverts of radiation per hour was detected inside a double-entry door at the No. 3 reactor building. At 2:31 p.m., the radiation level was measured at 300 millisieverts or higher per hour to the north of the door.

Both levels were well above the upper limit of 250 millisieverts for an entire year under the plant's safety standards for workers. But the workers who were trying to bring the situation under control at the plant were not informed of the levels.

When the Great East Japan Earthquake struck on March 11, the No. 1, No. 2 and No. 3 reactors all automatically shut down. But the tsunami crippled the emergency generators, leading to a total power failure that prevented the cooling systems from functioning.

The TEPCO data also showed high levels of hydrogen may be emitting from the damaged core of the No. 3 reactor on March 13, when TEPCO started injecting seawater to cool the reactor.

The following day around 11 a.m., a hydrogen explosion destroyed the upper part of the No. 3 reactor building. Seven TEPCO workers were injured in the blast.

TEPCO's public relations department said the company has informed the public that significant levels of radiation have been detected at the plant, but it disclose specific data after a thorough review of the figures is completed.

Keiji Miyazaki, professor emeritus of nuclear reactor engineering at Osaka University, criticized TEPCO's policy.

He said such important data should be immediately released to ensure the safety of the public and workers at the plant, especially in an emergency like the Fukushima nuclear accident.

Miyazaki said TEPCO's decision to conceal the data must be scrutinized.

Failure to release radiation data in the early stages of the crisis is said to have delayed the evacuations of communities near the plant.

Kiyoshi Sakurai, another nuclear power expert, said a thorough examination is needed not only on TEPCO's unpublished data, but also verbal communications of those involved, instructions issued by the central government and TEPCO, and the communication structure between management and workers at the plant.

...A sewage plant in eastern Tokyo detected a highly radioactive substance in incinerator ash shortly after the nuclear crisis began at the Fukushima No. 1 nuclear power plant, metropolitan government sources revealed Friday. The radioactive intensity of the substance was 170,000 becquerels per kilogram, the unnamed sources said. The ash, which has been recycled into construction materials, including cement, was collected from a sludge plant in Koto Ward in March. At almost at the same time that month, a radioactive substance with a radioactive intensity ranging from 100,000 to 140,000 becquerels per kg was also detected in ash at two other Tokyo sewage plants in Ota and Itabashi wards, the sources said. After a month, the radiation levels had dropped to 15,000 to 24,000 becquerels per kg at the three sewage plants, they added...(Kyodo/Japan Times)


2,000 millisieverts, or 2 sieverts, per hour radiation was detected inside the southeast double door of the Reactor 1 reactor building. Measurement was done by a remote-controlled robot on May 13.

A worker at Japan's tsunami-crippled Fukushima Daiichi nuclear power plant died today, plant operator Tokyo Electric Power Co said, bringing the death toll at the complex to three since a massive earthquake and tsunami in March. The cause of the death was unknown. The man, in his 60s, was employed by one of Tokyo Electric's contractors and started working at the plant yesterday. He was exposed to 0.17 millisieverts of radiation today, Tokyo Electric said. The Japanese government's maximum level of exposure for male workers at the plant is 250 millisieverts for the duration of the effort to bring it under control. The worker fell ill 50 minutes after starting work at 6am on Saturday and brought to the plant's medical room unconscious...(The Independent)

The first map of ground surface contamination within 80 kilometers of the crippled Fukushima No. 1 nuclear power plant shows radiation levels higher in some municipalities than those in the mandatory relocation zone around the Chernobyl plant. The map, released May 6, was compiled from data from a joint aircraft survey undertaken by the Ministry of Education, Culture, Sports, Science and Technology and the U.S. Department of Energy. It showed that a belt of contamination, with 3 million to 14.7 million becquerels of cesium-137 per square meter, spread to the northwest of the nuclear plant....(Asahi Shimbun)

The U.S. government has abandoned efforts to monitor elevated levels of radiation that infiltrated the nation’s water and milk in the wake of a nuclear catastrophe in Japan.

The U.S. Environmental Protection Agency has faced stiff criticism for its slow and spotty monitoring of radioactive iodine, cesium and other materials that were ejected into the atmosphere after the Fukushima nuclear power plant was struck by a tsunami in early March. The material fell on the United States in rainwater and was ingested by cows, which passed it through into their milk.

Radiation levels in some milk and rain samples have exceeded normal long-term federal drinking water standards, but EPA officials have described the levels as almost completely safe. Anti-nuclear power activists have accused the federal government of downplaying the health risks in an effort to protect the nuclear power industry and predicted that the radioactive isotopes will lead to a rash of cancers.

Diet against radiation sickness

may 9

Macrobiotic Diet Prevents Radiation Sickness Among A-Bomb Survivors in Japan - In August, 1945, at the time of the atomic bombing of Japan, Tatsuichiro Akizuki, M.D., was director of the Department of Internal Medicine at St. Francis's Hospital in Nagasaki. Most patients in the hospital, located one mile from the center of the blast, survived the initial effects of the bomb, but soon after came down with symptoms of radiation sickness from the fallout that had been released. Dr. Akizuki fed his staff and patients a strict macrobiotic diet of brown rice, miso soup, wakame and other sea vegetables, Hokkaido pumpkin, and sea salt and prohibited the consumption of sugar and sweets. As a result, he saved everyone in his hospital, while many other survivors in the city perished from radiation sickness.

I gave the cooks and staff strict orders that they should make unpolished whole-grain rice balls, adding some salt to them, prepare strong miso soup for each meal, and never use sugar. When they didn't follow my orders, I scolded them without mercy, 'Never take sugar. Sugar will destroy your blood!'...

This dietary method made it possible for me to remain alive and go on working vigorously as a doctor. The radioactivity may not have been a fatal dose, but thanks to this method, Brother Iwanaga, Reverend Noguchi, Chief Nurse Miss Murai, other staff members and in-patients, as well as myself, all kept on living on the lethal ashes of the bombed ruins. It was thanks to this food that all of us could work for people day after day, overcoming fatigue or symptoms of atomic disease and survive the disaster" free from severe symptoms of radioactivity.
