"Nuclear vaporization of an operational nuclear reactor and its spent fuel pool has the potential to release 50 to 100 times the biologically significant radioactivity released by the Chernobyl accident, resulting in contamination of a large portion of the world's food producing ecosystems." Source, here. In the U.S. alone, there are over 60,000 metric tons of spent fuel that are lying around nuclear plant facilities from coast to coast. The total amount of plutonium in the spent fuel waste makes it also a proliferation risk - the U.S. spent fuel inventories could be processed to make millions of atomic bombs. Some reactors and their 'pools' are located near fault lines and seashores. All are vulnerable to terrorist attack or sabotage. In aging pool structures, cracks in foundations can form and result in leaks of highly radioactive water into the subsurface or into rivers, lakes and the sea. This has happened already on various instances in the U.S. The Edwin 1 Hatch nuclear plant in the State of Georgia experienced a spent fuel pool leak in 1986 that spilled tens of thousands of gallons into storm drains and wetlands.

An uncontrolled fire within a spent fuel pond at Fukushima Units 1, 2, 3, 4, 5 or 6 or at other stricken Japanese plants - called a 'propagating zirconium cladding fire' - could have the potential of releasing quantities of radioactive poisons exceeding the equivalent of one or more Chernobyls.
Taro Kono, a Lower House lawmaker of the Liberal Democratic Party, told reporters on April 26 that instead of holding mass demonstrations, a more effective approach would be for the people to directly visit the offices of lawmakers to express their views on nuclear policy. Kono said both the ruling Democratic Party of Japan and the LDP are beneficiaries of major electric utilities and naturally lean toward protecting their vested interests. "Rather than 1 million people engaging in demonstrations, I believe it is far more effective if 1 million people went to the offices of politicians and directly told lawmakers or their secretaries their views on the issue, and tell them that unless they consider shifting sources of energy, they would not be receiving your support," he said.
“We want genpatsu [nuclear power plant] in Tokyo!”
“Japanese nuclear power plants are so safe that we could even build one in Tokyo Bay.”
“Radiation can’t get to you if you’re smiling. It only gets to people who are worried.”
“Fukushima has become famous without doing anything. It beat Hiroshima and Nagasaki."
“It’s safe to drink plutonium."
“We couldn’t build a nuclear power plant if we thought about possible accidents. So, we just suck it up.”
“Even if radiation sterilizes your semen, new semen will be produced.
The gene god is watching over your semen."
“The lethal dose of salt is 200 grams, and that of plutonium is 32 grams.
Plutonium poisoning is no big deal."
“Radiation is good for your health."
“Citizens shouldn’t be allowed to measure radiation levels.”
The move came after a radiation test, issued by city authorities,
detected 84 becquerelsof radioactive cesium per kilogram of Sukagawa hay. While Sukagawa is approximately 60 kilometers away from the damaged Fukushima No. 1 Nuclear Power Plant, some people had expressed concern about using Fukushima hay because it came to light that rice straw in extensive areas of the Tohoku region was tainted with radiation
John William Gofman (September 21, 1918 - August 15, 2007) was an American scientist and advocate. He was Professor Emeritus of Molecular and Cell Biology at University of California at Berkeley. Some of his early work was on the Manhattan Project, and he shares patents on the fissionability of uranium-233 as well as on early processes for separating plutonium from fission products. Dr. Gofman later worked in medicine and led the team that discovered and characterized lipoproteins in the causation of heart disease. In 1963, he established the Biomedical Research Division for the Livermore National Laboratory, where he was on the cutting edge of research into the connection between chromosomal abnormalities and cancer.
Gofman promoted a linear no-threshold model for the dangers of radiation, suggesting that even small doses over time could prove harmful. (WIKI)
Strontium 90 was measured in Yokohama, Kouhokuku. (5 mins by car from my apartment.)
In the simplest put, it’s over.
The amount was 195 Bq/kg.
Detected by a university staff teaching engineering, so the measurement is trustworthy.
It has nothing to do with the historical world-wide nuclear test, because it was measured on the roof of and [sic] apartment, which was built only 5 years ago. […]
The location was randomly chosen. The person who randomly found it is very upset and confused. [...]

I have a question? Folks in Japan know about Chernobyl, right? They know there is a large 1000 year dead zone around it, right? Why do they think Japan is different and can be decomtaminated? It can't be because of faith in Tepco.

A two-dimensional transient model for the transport of dissolved constituents through porous media originally developed at Oak Ridge National Laboratory (ORNL) has been expanded and modified. Transport mechanisms include: convection, hydrodynamic dispersion, chemical sorption, and first-order decay.
The transport of a dissolved constituent by ground water through sorbing porous media is controlled by carrier fluid advection, hydrodynamic dispersion, molecular diffusion, chemical reactions, and sorption on the media and decay. Mathematical equations to describe these phenomena have been formulated for various physical and chemical properties by many investigators. Reeves and Ouguid (1975) and Ouguid and Reeves (1976) have provided full background information concerning transport equation development and Galerkin finite-element techniques. Emphasis here will be placed upon modification and expansion to their original work.
This is an essential aspect in the application of the model to field situations in which the scale length of dispersivities is small relative to that spatial discretization (Ergatoudis, et al. 1968,
Finlayson 1972, Zienkiewicz 1977).
The waste flux at any point in the region is due to two mechanisms, advection and dispersion.
The sample problem of transport from a seepage pond reported by Duguid and Reeves (1976) is used to compare the simulation by the original computer codes (Reeves and Duguid 1975, Duguid and Reeves 1976) with that by the new waste transport code coupled with the revised water-flow code (Yeh and Hard 1980). The seepage pond is assumed to be situated near a stream as shown in Fig. 9. The system is composed of a highly permeable sand with soil properties shown in Fig. 10. A flux of 4.0 X 10 cm cm sec" , directed vertically downward from bottom of the pond, provides the only driving force for moving the contaminant toward the stream.
On 12 October an emergency drill simulating a magnitude 8 earthquake near Fukushima Daiichi will be carried out. 30 workers will be employed to install fire trucks and hoses to pump seawater in order to confirm that the cooling of the reactors can be restored within 3 hours.
Oct 12 (Reuters) - Japan Atomic Power said on Wednesday that repairing its
quake-hit Tokai Daini nuclear reactor will take until August next year, about nine
months longer than originally planned, as the facility's turbines need extra work.
The 1,100-megawatt reactor in Tokaimura, 110 km northeast of Tokyo, has come under
the spotlight this week as the town's mayor has called on the government to
decommission it. The 33-year old reactor has an allowed life of 40 years.

Roughly 5,000 square miles of Japanese territory would be covered by a national program to remove radioactive material released by the Fukushima Daiichi atomic facility, the Asahi Shimbun reported on Wednesday (see GSN, Oct. 11)
Washington (Platts)--12Oct2011/512 am EDT/912 GMT
The US Nuclear Regulatory Commission should move more quickly to implement actions to address lessons learned from the Fukushima accident in Japan, nuclear power critics told the regulator at a briefing Tuesday.
NRC staff earlier in October sent the commission its proposed plan for how to prioritize recommendations from an agency task force on how to improve the ability of US nuclear power plants to withstand floods, earthquakes and station blackouts.

TOKYO -- Japanese officials have found a small area in Tokyo with higher levels of radiation than evacuation zones around the Fukushima nuclear plant.
Tokyo's Setagaya city's mayor says concerned parents monitoring for radiation asked them to conduct further tests on a roadside spot near a kindergarten. Its radioactivity slightly exceeded that of an area about 25 miles (40 kilometers) from the Fukushima Dai-ichi plant.
Mayor Nobuto Hosakai says the cause is being investigated. He says rainwater containing radioactive particles had been dripping from the roof of a building by the sidewalk.
Officials in Yokohama, Japan’s second largest city, are investigating soil samples after a radioactive substance was found in sediment atop an apartment building about 155 miles (250 kilometers) from the Fukushima No. 1 nuclear plant, according to news reports.
The discovery has raised concerns that leaked radiation from three Fukushima reactors that suffered meltdowns after the March earthquake and tsunami may be more widespread than thought, The Japan Times reported Wednesday.
The findings come after a travel alert issued by the U.S. government last week, warning Americans in Japan to avoid areas near the stricken reactors.
The alert recommends that U.S. citizens stay away from areas within 20 kilometers (12 miles) of the nuclear facility. The State Department also admonished Americans to stay away from territory northwest of the plant in a zone that Japan calls the "Deliberate Evacuation Area." The zone includes Iitate-mura, the Yamagiya district of Kawamata-machi, Katsurao-mura, Namie-machi and parts of Minamisoma.
