An unstoppable tide of radioactive trash and chemical
waste from Fukushima is pushing ever closer to North America. An estimated
20 million tons of smashed timber, capsized boats and industrial wreckage
is more than halfway across the ocean, based on sightings off Midway by
a Russian ship's crew. Safe disposal of the solid waste will be monumental
task, but the greater threat lies in the invisible chemical stew mixed
with sea water.

This new triple disaster floating from northeast Japan is an unprecedented nuclear, biological and chemical (NBC) contamination event. Radioactive isotopes cesium and strontium are by now in the marine food chain, moving up the bio-ladder from plankton to invertebrates like squid and then into fish like salmon and halibut. Sea animals are also exposed to the millions of tons of biological waste from pig farms and untreated sludge from tsunami-engulfed coast of Japan, transporting pathogens including the avian influenza virus, which is known to infect fish and turtles. The chemical contamination, either liquid or leached out of plastic and painted metal, will likely have the most immediate effects of harming human health and exterminating marine animals.

Many chemical compounds are volatile and can evaporate with water to form clouds, which will eventually precipitate as rainfall across Canada and the northern United States. The long-term threat extends far inland to the Rockies and beyond, affecting agriculture, rivers, reservoirs and, eventually, aquifers and well water. Falsifying Oceanography

A nuclear plant in Plymouth has been shut down after a suspected leak from the one of the plants safety relief valves. “An Nuclear Regulator Commission Resident Inspector was at the the Pilgrim nuclear power plant Monday to monitor the shutdown, which took place without any complications,” said Nuclear Regulator Commission spokesman Neil Sheehan. The Nuclear Regulator Commission says the Pilgrim nuclear power plant was shut down due to leakage from a valve which provides overpressure protection for the plant’s reactor coolant system. The NRC, in a statement said the valve opens when required, “to discharge reactor steam into the suppression pool, a large, donut-shaped reservoir of water located at the bottom of the reactor building.” NRC inspectors will also monitor the repairs to the valve and then also monitor the service restoration when the plans are completed.
U.S. Government Confirms Link Between Earthquakes and Hydraulic Fracturing at Oil Price - 0 views

On 5 November an earthquake measuring 5.6 rattled Oklahoma and was felt as far away as Illinois. Until two years ago Oklahoma typically had about 50 earthquakes a year, but in 2010, 1,047 quakes shook the state. Why? In Lincoln County, where most of this past weekend's seismic incidents were centered, there are 181 injection wells, according to Matt Skinner, an official from the Oklahoma Corporation Commission, the agency which oversees oil and gas production in the state. Cause and effect? The practice of injecting water into deep rock formations causes earthquakes, both the U.S. Army and the U.S. Geological Survey have concluded.
-
The U.S. natural gas industry pumps a mixture of water and assorted chemicals deep underground to shatter sediment layers containing natural gas, a process called hydraulic fracturing, known more informally as “fracking.” While environmental groups have primarily focused on fracking’s capacity to pollute underground water, a more ominous byproduct emerges from U.S. government studies – that forcing fluids under high pressure deep underground produces increased regional seismic activity. As the U.S. natural gas industry mounts an unprecedented and expensive advertising campaign to convince the public that such practices are environmentally benign, U.S. government agencies have determined otherwise. According to the U.S. Army’s Rocky Mountain Arsenal website, the RMA drilled a deep well for disposing of the site’s liquid waste after the U.S. Environmental Protection Agency “concluded that this procedure is effective and protective of the environment.” According to the RMA, “The Rocky Mountain Arsenal deep injection well was constructed in 1961, and was drilled to a depth of 12,045 feet” and 165 million gallons of Basin F liquid waste, consisting of “very salty water that includes some metals, chlorides, wastewater and toxic organics” was injected into the well during 1962-1966.
-
Why was the process halted? “The Army discontinued use of the well in February 1966 because of the possibility that the fluid injection was “triggering earthquakes in the area,” according to the RMA. In 1990, the “Earthquake Hazard Associated with Deep Well Injection--A Report to the U.S. Environmental Protection Agency” study of RMA events by Craig Nicholson, and R.I. Wesson stated simply, “Injection had been discontinued at the site in the previous year once the link between the fluid injection and the earlier series of earthquakes was established.” Twenty-five years later, “possibility” and ‘established” changed in the Environmental Protection Agency’s July 2001 87 page study, “Technical Program Overview: Underground Injection Control Regulations EPA 816-r-02-025,” which reported, “In 1967, the U.S. Army Corps of Engineers and the U.S. Geological Survey (USGS) determined that a deep, hazardous waste disposal well at the Rocky Mountain Arsenal was causing significant seismic events in the vicinity of Denver, Colorado.” There is a significant divergence between “possibility,” “established” and “was causing,” and the most recent report was a decade ago. Much hydraulic fracturing to liberate shale oil gas in the Marcellus shale has occurred since.

Rising water, falling journalism | Bulletin of the Atomic Scientists [17Jun11] - 0 views

at the Fort Calhoun Nuclear Power Station near Blair, Nebraska, the river is already lapping at the Aqua Dams -- giant plastic tubes filled with water -- that form a stockade around the plant's buildings. The plant has become an island.
-
The Nuclear Regulatory Commission (NRC) issued a "yellow finding PDF" (indicating a safety significance somewhere between moderate and high) for the plant last October, after determining that the Omaha Public Power District (OPPD) "did not adequately prescribe steps to mitigate external flood conditions in the auxiliary building and intake structure" in the event of a worst-case Missouri River flood. The auxiliary building -- which surrounds the reactor building like a horseshoe flung around a stake -- is where the plant's spent-fuel pool and emergency generators are located.
-
OPPD has since taken corrective measures, including sealing potential floodwater-penetration points, installing emergency flood panels, and revising sandbagging procedures. It's extremely unlikely that this year's flood, no matter how historic, will turn into a worst-case scenario: That would happen only if an upstream dam were to instantaneously disintegrate. Nevertheless, in March of this year the NRC identified Fort Calhoun as one of three nuclear plants requiring the agency's highest level of oversight. In the meantime, the water continues to rise

Japan's Nukes Following Earthquake - 1 views

TEPCO has just released "diaries" from early in the accident giving us a better view of the sequence of events from the operators point of view.
-
The bulk of the materials, distributed on discs with digital files, show reams of raw numerical data. They include photos of broadsheet computer printouts and other formatted charts with thousands of data points for measurements of reactor heat, pressure, water levels, fuel rod positions and the status of cooling pumps, among other functions. Tokyo Electric, or Tepco, also released a smaller batch of more recent documents highlighting its various efforts to restore electric power to each of the reactors, a task that was achieved on April 26. But a series of what Tepco terms reactor "diaries" from the first 48 hours after the quake include the most visually arresting materials. These feature snapshots of whiteboards on which plant employees—11 of whom remained in each of the plant's three control rooms—jotted down status updates on the progress of the reactor shutdowns and steadily increasing radiation levels around the facility.

Using red, black or blue ink markers, the plant operators appear to have scribbled down the notes quickly. Many are smudged or illegible. Others depict complex diagrams and are peppered with technical jargon or acronyms such as SBO for "station blackout." http://online.wsj.com/article/SB10001424052748704281504576329011846064194.html

Fukushima: Towards the Formation of a Radioactive Graveyard in the Pacific Ocean? [22Oc... - 0 views
-
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.
-
Initially reports had quieted concerns by stating that the materials would be diluted so vastly that the radioactivity would not be able to accumulate, and would not affect the environment. The experts claimed they would track the deposition and floating radioactive debris field making its way on a trans-Pacific trip to the United States. Apparently, the experts in Japan didn't get the message. The Japanese regularly tested the seawater only for 'popular' Iodine and Cesium isotopes instead of all known fission-produced radioactive materials, for the first 3 months after the disaster. By March 31st, radioactive contamination concentration was 4,385 times the legal limit, up from 3,355 times on Tuesday, according to Kyodo. In response, the government had pledged to increase radiation monitoring on land and by sea and to consider increasing the evacuation zone — however time has shown little action would follow these vows.

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.

What are officials hiding about Fukushima? [23Oct11] - 0 views
-
The rainwater data is just one example of failings in how Canada monitored radiation from Fukushima. The accident has exposed a pattern of nonchalance and seeming willful ignorance on the part of Canadian health authorities when it comes to the dangers of nuclear power. Drinking water is another example. In Vancouver, the city did its first test of the drinking-water supply on March 16, a few days after the Fukushima accident on March 11. No radiation was detected in that day’s sample. But this was to be expected because it took until March 18 and 19 for the radioactive plume from Fukushima to first hit the west coast of Canada. Instead of continuing with frequent monitoring, the city didn’t do another radiation test until March 25—nine days after the first test. On March 25, testing detected alpha radiation at 0.11 becquerels per litre in the drinking water at the city’s Seymour-reservoir intake. Alpha radiation comes from isotopes like plutonium-238 and is the most dangerous form of radiation when ingested or inhaled. The level at the Seymour intake was lower than the current Canadian and World Health Organization guideline of 0.5 becquerels per litre in drinking water. On the other hand, the WHO guideline used to be 0.1 Bq per litre before it was adjusted higher in the mid-2000s.
-
That nine-day hole between March 16 and 25 is exactly when SFU prof Starosta found massive radiation spikes in rainwater in Burnaby. Did the alpha radiation ever surpass the ceiling? We can’t say for sure. Because of the long gap between tests, it’s not clear how high radiation levels may have gotten and for how long. When the city tested its drinking water again on March 28, the alpha radiation was no longer detectable. Food is another big question mark. The Canadian Food Inspection Agency briefly tested Japanese food imports from the area around Fukushima, but it dropped those measures in June. Canada now relies on Japanese authorities to screen contaminated food. But Japan’s food inspections have proven to be highly controversial since Fukushima. The country has no centralized food-inspection system, and poor monitoring after Fukushima allowed food contaminated with radiation to be sold to Japanese consumers.
-
Meanwhile, it’s becoming clear that the radiation has spread much farther across Japan than government officials have acknowledged. Citizen monitoring groups have found 22 “hot spots” in Tokyo where radiation levels are higher than the level at which zones were considered contaminated near Chernobyl, the New York Times reported on October 14. The CFIA also told the Straight it has no plans to monitor food products from the Pacific Ocean fishery. You’d think this would be a concern, because many fish caught in the Pacific still have large amounts of radiation months after the accident, according to data reported on the website of the Japanese government fisheries agency. In September, 21 Japanese fish catches exceeded the Japanese radiation ceiling—the same number as in August. Two catches in September exceeded the ceiling for radioactive cesium by more than four times.

CPS must die [24Oct07} - 0 views
-
Collectively, Texas eats more energy than any other state, according to the U.S. Department of Energy. We’re fifth in the country when it comes to our per-capita energy intake — about 532 million British Thermal Units per year. A British Thermal Unit, or Btu, is like a little “bite” of energy. Imagine a wooden match burning and you’ve got a Btu on a stick. Of course, the consumption is with reason. Texas, home to a quarter of the U.S. domestic oil reserves, is also bulging with the second-highest population and a serious petrochemical industry. In recent years, we managed to turn ourselves into the country’s top producer of wind energy. Despite all the chest-thumping that goes on in these parts about those West Texas wind farms (hoist that foam finger!), we are still among the worst in how we use that energy. Though not technically “Southern,” Texans guzzle energy like true rednecks. Each of our homes use, on average, about 14,400 kilowatt hours per year, according to the U.S. Energy Information Administration. It doesn’t all have to do with the A/C, either. Arizonans, generally agreed to be sharing the heat, typically use about 12,000 kWh a year; New Mexicans cruise in at an annual 7,200 kWh. Don’t even get me started on California’s mere 6,000 kWh/year figure.
-
Let’s break down that kilowatt-hour thing. A watt is the energy of one candle burning down. (You didn’t put those matches away, did you?) A kilowatt is a thousand burnin’ candles. And a kilowatt hour? I think you can take it from there. We’re wide about the middle in Bexar, too. The average CPS customer used 1,538 kilowatt hours this June when the state average was 1,149 kWh, according to ERCOT. Compare that with Austin residents’ 1,175 kWh and San Marcos residents’ 1,130 kWh, and you start to see something is wrong. So, we’re wasteful. So what? For one, we can’t afford to be. Maybe back when James Dean was lusting under a fountain of crude we had if not reason, an excuse. But in the 1990s Texas became a net importer of energy for the first time. It’s become a habit, putting us behind the curve when it comes to preparing for that tightening energy crush. We all know what happens when growing demand meets an increasingly scarce resource … costs go up. As the pressure drop hits San Anto, there are exactly two ways forward. One is to build another massively expensive power plant. The other is to transform the whole frickin’ city into a de-facto power plant, where energy is used as efficiently as possible and blackouts simply don’t occur.
-
CPS has opted for the Super Honkin’ Utility model. Not only that — quivering on the brink of what could be a substantial efficiency program, CPS took a leap into our unflattering past when it announced it hopes to double our nuclear “portfolio” by building two new nuke plants in Matagorda County. The utility joined New Jersey-based NRG Energy in a permit application that could fracture an almost 30-year moratorium on nuclear power plant creation in the U.S.
