AUDIO Cleaning Up Fukushima: A Challenge To The Core : NPR, 13 April 2011, “…….Nuclear engineers working at the Japanese plant are dealing with two problems at the same time: They are working to fully stabilize the plant’s reactors, and they are trying to control the release of radioactive material.
It could take weeks or months to stabilize the reactors. And containing and cleaning up the radioactive material could take at least 10 years, at a cost of more than $10 billion. Even though many of the details about what’s happening at the reactors are not known, experts can predict the tasks ahead for workers.
Back in 1979, nuclear engineer Lake Barrett coordinated cleanup at Pennsylvania’s Three Mile Island reactor for the Nuclear Regulatory Commission. He breaks down the cleanup challenge to the basic elements of ancient Greece. The Greeks had fire, air, water and earth. At Fukushima, it’s pretty much the same: energy, air, water and solids.
“So if you go back to the four basic principles, what the engineers are doing in Fukushima is first they have to deal with energy dissipation — that is the cooling of the decay products in the core — keep the core cool,” Barrett says……
For now, there’s a watery mess at the plant.
“In the case of Three Mile Island, we had about half a million gallons of very highly radioactive water in the basement of the containment building,” Barrett says. “It was about 10 feet deep. They’re facing the same situation in Fukushima, but they have three of these cores that have severe damage to them, so they probably have tens of millions of gallons of the same highly radioactive water that they’re dealing with.”…..
Once the energy, gas and water aspects of the nuclear crisis are under control, the most highly radioactive materials — the solids in the reactor cores — remain. Just getting to them is a problem……
Leo Lessard, a nuclear engineer at the French company Areva, says just getting to the cores at Fukushima Dai-ichi is going to be much more difficult than it was at Three Mile Island. For starters, the tops of two buildings have collapsed, so that debris will have to be cleared.
“A lot of that material is probably very radioactive, so there will have to be shielding and other precautions incorporated in order to protect workers who have to do some manual operations in those areas,” Lessard says….
“In that case, you have a tremendously high radiation field, as opposed to having it underwater, where the water is providing complete shielding,” Lessard says. He expects the cleanup to take more than a decade.
Barrett says to count on cleanup costing $10 billion. Engineers can break the problem down to the basics, and they know how to do each individual step — but nobody’s ever tried a nuclear cleanup on this scale before.

Timeline: Nuclear plant accidents. BBC News, 12 April 2011 The nuclear crisis in Japan has revived fears over the safety of nuclear power and the potential danger posed to public health when things go wrong.There have been a number of serious nuclear incidents since the 1950s. Below are details of the most serious: Continue reading
This threat should disqualify the site, especially when combined with the fact that Southwestern water resources will be polluted with radiation as waste canisters at Yucca Mountain disintegrate over time.
Solving the problem of nuclear waste The Hill’s Congress Blog By Rep. Shelley Berkley (D-Nev.) 12 April 11 – At a time when our nation is making tough choices about spending, I am amazed that Congressman John Shimkus (R-Ill.) and other House Republicans are demanding we dump $100 billion into Yucca Mountain. This shuttered boondoggle, located 90 minutes from Las Vegas, is nothing more than an empty hole in the Nevada desert.
While some are seeking to use the tragic events in Japan to once again push for moving nuclear waste to Nevada, they fail to mention that Yucca Mountain is located smack in the middle of an earthquake zone. Continue reading

Research and Markets: Global Investment in Renewable Energy , | Business Wire, 11 April 11, The world’s hunger for energy and power is growing at a rapid pace. However, conventional fuels such as natural gas and coal only have a limited supply to provide for our insatiable demand for energy. So what happens when these conventional sources of energy run out? The world is going to become more and more dependent on renewable energy resources. Therefore, foreseeing this near future event, governments around the world are already developing and investing in renewable energy sources. Continue reading
Radiation in Ontario higher since Japan crisis: officials TheRecord -, 12 April 11, TORONTO — Elevated levels of radiation have been found in Ontario since the Japanese nuclear disaster but health authorities say people should not be alarmed.On Tuesday, Energy Minister Brad Duguid said radiation levels have gone up slightly since a devastating earthquake struck off the northeast coast of Japan on March 11 crippling the Fukushima Daiichi nuclear reactors.Some U.S. states have also found elevated radiation levels, Duguid said. But he added there is no reason for alarm here as officials regularly test the air, water and food.The news comes the same day that Japan increased the severity rating of the crisis at the Fukushima nuclear plant to the same level as the Chornobyl disaster….

British monitoring of water commenced in the 1950s. The records of this early monitoring are unavailable in Australia. As British nuclear weapons testing in Australia commenced in the early l950s, this data is of great importance.
Propaganda Paul Langley’s Nuclear History Blog, 13 April 11, IntroductionFrom 1957 to 1978 the Australian Government carried out dissections on the bodies of people who had died of illness or accident. These dissections were carried out to monitor the amount of Strontium 90, a radioactive element, absorbed by Australians. Strontium 90 was a component of the fallout deposited from nuclear tests conducted in Australia, the Pacific and China. Continue reading

The oil leak in the Gulf was terrifying because of its relentless filthy incontinence. The leak of radiation is terrifying because it remains unseen and is in part dependent on the whim of the wind.
As radiation leaks, truth is slow to follow BBC Matt Frei , 12 April 2011 As radiation leaks, truth is slow to follow. I t is cruelly ironic that as we approach the first anniversary of the BP oil spill in the Gulf of Mexico, the world should once again be transfixed by the inability of humans to plug a poisonous leak created by our need for energy.
Last year it was the spewing orifice at the bottom of the sea brought to us 24/7 courtesy of the dozen or so “spillcams” that became a fixture in the corner of just about every cable news TV screen.
This year we have the unseen wafts, leaks and seepages of radiation from the Fukushima Daichi nuclear power plant in Japan. The fact that the threat level of this crisis has now been raised – one month later – to seven – the highest possible – is alarming.
The fact that Japanese authorities insist the radiation level is still one-tenth that of Chernobyl – the only other nuclear disaster that has earned a seven – is puzzling.
The leaking information has made the leaking radiation all the more perplexing. Not surprisingly, the patient people of Japan are getting angry. They feel – not for the first time – that their government and Tepco, the power company, have been economical with the truth.
