Something is going wrong. TEPCO has started to use fresh water taken from the river to cool the reactors, because the treated water that it has been using is running low.From Yomiuri Shinbun (10:23PM JST 7/15/2011):

TEPCO announced on July 15 that the company started to use the fresh water from outside source to supplement the treated water it has been using to cool the reactors for two weeks. The contaminated water treatment system at Fukushima I Nuclear Power Plant is not functioning well.

If the outside water is used, that will increase the amount of contaminated water. TEPCO is trying to identify the cause of the problem.

The impacts on the ocean of releases of radionuclides from the Fukushima Dai-ichi nuclear power plants remain unclear. However, information has been made public regarding the concentrations of radioactive isotopes of iodine and cesium in ocean water near the discharge point. These data allow us to draw some basic conclusions about the relative levels of radionuclides released which can be compared to prior ocean studies and be used to address dose consequences as discussed by Garnier-Laplace et al. in this journal.(1) The data show peak ocean discharges in early April, one month after the earthquake and a factor of 1000 decrease in the month following. Interestingly, the concentrations through the end of July remain higher than expected implying continued releases from the reactors or other contaminated sources, such as groundwater or coastal sediments. By July, levels of 137Cs are still more than 10 000 times higher than levels measured in 2010 in the coastal waters off Japan. Although some radionuclides are significantly elevated, dose calculations suggest minimal impact on marine biota or humans due to direct exposure in surrounding ocean waters, though considerations for biological uptake and consumption of seafood are discussed and further study is warranted.

there was no large explosive release of core reactor material, so most of the isotopes reported to have spread thus far via atmospheric fallout are primarily the radioactive gases plus fission products such as cesium, which are volatilized at the high temperatures in the reactor core, or during explosions and fires. However, some nonvolatile activation products and fuel rod materials may have been released when the corrosive brines and acidic waters used to cool the reactors interacted with the ruptured fuel rods, carrying radioactive materials into the ground and ocean. The full magnitude of the release has not been well documented, nor is there data on many of the possible isotopes released, but we do have significant information on the concentration of several isotopes of Cs and I in the ocean near the release point which have been publically available since shortly after the accident started.

We present a comparison of selected data made publicly available from a Japanese company and agencies and compare these to prior published radionuclide concentrations in the oceans. The primary sources included TEPCO (Tokyo Electric Power Company), which reported data in regular press releases(3) and are compiled here (Supporting Information Table S1). These TEPCO data were obtained by initially sampling 500 mL surface ocean water from shore and direct counting on high-purity germanium gamma detectors for 15 min at laboratories at the Fukushima Dai-ni NPPs. They reported initially results for 131I (t1/2 = 8.02 days), 134Cs (t1/2 = 2.065 years) and 137Cs (t1/2 = 30.07 years). Data from MEXT (Ministry of Education, Culture, Sports, Science and Technology—Japan) were also released on a public Web site(4) and are based on similar direct counting methods. In general MEXT data were obtained by sampling 2000 mL seawater and direct counting on high-purity germanium gamma detectors for 1 h in a 2 L Marinelli beaker at laboratories in the Japan Atomic Energy Agency. The detection limit of 137Cs measurements are about 20 000 Bq m–3 for TEPCO data and 10 000 Bq m–3 for MEXT data, respectively. These measurements were conducted based on a guideline described by MEXT.(5) Both sources are considered reliable given the common activity ratios and prior studies and expertise evident by several Japanese groups involved in making these measurements. The purpose of these early monitoring activities was out of concern for immediate health effects, and thus were often reported relative to statutory limits adopted by Japanese authorities, and thus not in concentration units (reported as scaling factors above “normal”). Here we convert values from both sources to radionuclide activity units common to prior ocean studies of fallout in the ocean (Bq m–3) for ease of comparison to previously published data.

As the country awaits results from a nationwide safety study on the natural gas drilling process of fracking, a separate government investigation into contamination in a place where residents have long complained [1] that drilling fouled their water has turned up alarming levels of underground pollution. A pair of environmental monitoring wells drilled deep into an aquifer in Pavillion, Wyo., contain high levels of cancer-causing compounds and at least one chemical commonly used in hydraulic fracturing, according to new water test results [2] released yesterday by the Environmental Protection Agency.

The findings are consistent with water samples the EPA has collected from at least 42 homes in the area since 2008, when ProPublica began reporting [3] on foul water and health concerns in Pavillion and the agency started investigating reports of contamination there. Last year -- after warning residents not to drink [4] or cook with the water and to ventilate their homes when they showered -- the EPA drilled the monitoring wells to get a more precise picture of the extent of the contamination.

The Pavillion area has been drilled extensively for natural gas over the last two decades and is home to hundreds of gas wells. Residents have alleged for nearly a decade [1] that the drilling -- and hydraulic fracturing in particular -- has caused their water to turn black and smell like gasoline. Some residents say they suffer neurological impairment [5], loss of smell, and nerve pain they associate with exposure to pollutants. The gas industry -- led by the Canadian company EnCana, which owns the wells in Pavillion -- has denied that its activities are responsible for the contamination. EnCana has, however, supplied drinking water to residents.

No one wants to think about the massive aqueous deposition of radioactive materials into the Pacific Ocean, that much is now clear. By September estimates of released contamination had risen to over  3,500 terabecquerels of cesium-137 released into the sea directly from the plant between March 11 and the end of May. Another 10,000 terabecquerels of cesium fell into the ocean after escaping from the reactors in the form of steam.

"The question is, what is a reasonable interval to give people information?" said Dr. Robert Peter Gale, an American physician and expert on radiation who consulted on the 1986 nuclear disaster in Chernobyl and is now advising Japan's government. "Instead of just releasing each data point you get, sometimes it's better to base things on an average of readings over a period of time." Source: LA Times

Experts Don't Fear A Radiation Graveyard Water was constantly required for the workers to be able to get any cooling into Reactors 1-4, when water went in, steam came out.  The ocean quickly became the radiation dumping ground, as untold tonnes of contaminated water has been confirmed to have directly flowed into the ocean, and TEPCO continually assured Japanese citizens that the majority of dispersal would occur over the Pacific.

While readings of radiation in the air have returned to pre-3/11 levels in most areas of Japan — not including areas close to the plant and the so-called hot spots — the contamination of soil, which affects the food chain, could pose a long-term health risk, experts say. Iodine-131, cesium-134 and cesium-137 were released in large quantities by the nuclear plant, and if they are accumulated in the body, they could cause cancer.

Kunikazu Noguchi, lecturer at Nihon University and an often-quoted expert on radiological protection, assures that consumers need not worry too much about any produce on the market, because at present, radiation levels in most vegetables, meat, dairy and other foods, even those from Fukushima Prefecture, are far below the government's safety limits and often undetectable. But for consumers concerned about the few incidents of tainted food slipping through the government checks (such as the beef from cattle that had been fed with tainted straw in Fukushima, which was shipped nationwide in July), or families with small children, Noguchi suggests a simple way to minimize their radiation exposure through food: rinse it.

rinsing the food well before cooking, preferably with hot water, and/or boiling or stewing it, a large portion of radioactive elements can be removed. In his book, published in Japanese in mid-July, "Hoshano Osen kara Kazoku wo Mamoru Tabekata no Anzen Manyuaru" ("The Safety Manual for Protecting Your Family From Radiation Contamination"), Noguchi offers tips on how to prepare food, item by item, so consumers can reduce their radiation intake at home.

TEPCO announced on September 9 that 6 workers entered the reactor building of Reactor 3 at Fukushima I Nuclear Power Plant, and installed a water gauge to measure the amount of contaminated water in the basement. According to the company, the radiation exposure of the 6 workers was between 0.33 to 5.26 millisieverts. The measurement using the water gauge is set to start on or after September 12.

... TEPCO also disclosed the plan to start removing the debris from the upper floors of Reactors 3 and 4. The work will start in Reactor 3 on September 10, and it will start in Reactor 4 within this month. Upper floors of Reactors 3 and 4 are littered with damaged ceiling panels and exterior wall panels, and it is hoped that the spread of radioactive materials will be suppressed by removing the debris.

Removing the debris will stir up the radioactive materials instead of suppressing them, won't it? Not to mention exposing the workers to an inadvertent 10-plus sieverts/hour super hot spot, as it happened near the exhaust stack between Reactors 1 and 2?From the tweets by the worker at Fukushima I Nuke Plant, it is evident that TEPCO is fast running out of money (to spend on the accident, apparently not on its retiring executives) and carbon-based workers to do further work. The worker also tweeted a week or so ago that the construction people were active, already clearing debris in Reactor 4.

Extract Salmon is no longer cherished as a local specialty in northeast China, where people fear the fish have been contaminated by the radiation from the meltdown at the Fukshima nuclear plant in Japan following the devastating earthquake in March this year. “It has been a long-time privilege for me to preserve salmon at the request of relatives and friends but lately they have refused it, even when I called to offer them some,” said Xing Guo, a fishery worker in Fuyuan county on the border with Russia in the northeastern province of Heilongjiang. Guo’s mother told him not to eat salmon after she heard rumors that the fish had been contaminated in the Sea of Japan before making their migration to local fresh water. “I have seen some fish thrown in the rubbish bin outside. Not daring to eat it, those who received salmon as a present threw it away,” he said. End Extract http://www.wantchinatimes.com/news-subclass-cnt.aspx?cid=1103&MainCatID=11&id=20110930000055

The American phoenix is slowly rising again. Within five years or so, the US will be well on its way to self-sufficiency in fuel and energy. Manufacturing will have closed the labour gap with China in a clutch of key industries. The current account might even be in surplus.

Assumptions that the Great Republic must inevitably spiral into economic and strategic decline - so like the chatter of the late 1980s, when Japan was in vogue - will seem wildly off the mark by then. Telegraph readers already know about the "shale gas revolution" that has turned America into the world’s number one producer of natural gas, ahead of Russia. Less known is that the technology of hydraulic fracturing - breaking rocks with jets of water - will also bring a quantum leap in shale oil supply, mostly from the Bakken fields in North Dakota, Eagle Ford in Texas, and other reserves across the Mid-West. "The US was the single largest contributor to global oil supply growth last year, with a net 395,000 barrels per day (b/d)," said Francisco Blanch from Bank of America, comparing the Dakota fields to a new North Sea. Total US shale output is "set to expand dramatically" as fresh sources come on stream, possibly reaching 5.5m b/d by mid-decade. This is a tenfold rise since 2009.
