A very good purpose!

100% ecological? In nature such large amounts of radioactive material do not appear in one spot at the same time. It's a very clean source as long as it is contained. How do you keep it contained?

"The reactors in question were all shut down four days ago." If were shut down why they are injecting salt water and boron acid? Boron ??? to cool the "huge temperatures" released by "radioactive decay", that quickly fall down, and only is 0.2% after a day of shut down and it had passed fives days !!!

Kawecki Your statements are simply not factual. According to Dave Lochbaum, Director, Nuclear Safety for the Union of Concerned Scientists (David Lochbaum is one of the nation's top independent experts on nuclear power. At UCS, he monitors safety issues at the nation's nuclear power plants, and reports on concerns with the Nuclear Regulatory Commission -- Mr. Lochbaum is a nuclear engineer by training and worked in nuclear power plants for 17 year) the typical cool down time for a BWR (Boiling Water Reactor) is 30 days. See his article on Reactor Core Cooling In figure 2 the chart clearly shows that after complete shut-down the boil-off rate in the reactor core goes down to 100 gallons per minute one day after shut-down. After 5 days the boil-off rate has only dropped to between 60 and 80 gallions per minute. It takes 30 days for the boil off rate to drop to zero. That is with fully functioning set of back-up cooling systems. Tuning these things off is not like flipping off a light-switch or removing a boiling kettle from a stove. What is clear from even the muddled reports getting out is that the Fukushima reactors lost power to their back-up cooling systems and this is the issue plant workers are struggling to deal with. So, your statements are simply factually incorrect -- incorrect statements do nothing to address any real issue. J.R. Dunn has this to say about the events in Japan: “First, let's put the accidents in context: the Fukushima reactors survived one of the worst earthquakes in the historical record without breaking down catastrophically. This is a compliment to the designers (GE, in case anyone was wondering), the construction crews, and the operational teams. If the same had been true of Three Mile Island and Chernobyl, the accidents that occurred at those sites would have been of interest only to specialists. (Remember that TMI had a critical set of coolant valves put in backwards, while the Chernobyl reactor had no containment structure and was deliberately red-lined with all the safety features shut down, for reasons never adequately explained.) As for chances of a meltdown, we can quote the capable Dr. Robert Zubrin: "The reactors in question were all shut down four days ago. The control rods have been inserted, and the cores have been salted with boron. It is physically impossible for them to sustain a fission reaction of any kind at this point, let alone cause another Chernobyl. Only the fission-byproduct decay heat remains, and it is fading fast as the short half-life material... performs its decay reactions and ceases to exist." It is at this point as likely that the reactors could melt down as a car with an empty tank and all four tires stripped could win the Indy. “ Facts: World deaths per terawatt hour by energy source. Energy Source Death Rate (deaths per TWh) Coal – world average 161 (26% of world energy, 50% of electricity) Coal – China 278 Coal – USA 15 Oil 36 (36% of world energy) Natural Gas 4 (21% of world energy) Biofuel/Biomass 12 Peat 12 Solar (rooftop) 0.44 (less than 0.1% of world energy) Wind 0.15 (less than 1% of world energy) Hydro 0.10 (europe death rate, 2.2% of world energy) Hydro - world including Banqiao) 1.4 (about 2500 TWh/yr and 171,000 Banqiao dead) Nuclear 0.04 (5.9% of world energy) * The Banqiao Reservoir Dam is a dam on the River Ru in Zhumadian Prefecture, Henan province, China. It famously failed in 1975, causing more casualties than any other dam failure in history, and was subsequently rebuilt. Fact: Air pollution from coal plants and developing countries burning wood or coal inside their homes are one of the biggest causes of all kinds of death and illness. Fact: Nuclear energy has a far higher safety rating than any other form of useful industrial energy production. The rhetoric Greens and associated media are using is designed to make the disaster seem much worse than it is, to find someone to pin things on, and to shift public opinion in the direction of shutting down all nuclear plants no matter what the circumstances. (Germany has already shut down seven of its reactors for the next four months, just in case there's a magnitude 9 earthquake in Stuttgart.) Anybody who was around for Three Mile Island back in 1979 or Chernobyl in 1986 will recognize the cycle: first hysteria, then accusations, then more hysteria, then demands to return to the pre-modern era. The dishonesty in this should disgust anyone. P.S. MrWolf53, Your statement "that such large amounts of radiation do not appear in nature" is factually wrong: You receive 3.0 milliseiverts (100 millirem per year) from minerals, building materials, your counter-tops and solar radiation -- in fact life on earth would be impossible without it. Reactors which have not been hit by a 9.0 earthquake and a very large tsunami contain such radiation all the time – by design.

"in figure 2 the chart clearly shows that after complete shut-down the boil-off rate in the reactor core goes down to 100 gallons per minute one day after shut-down. After 5 days the boil-off rate has only dropped to between 60 and 80 gallions per minute." This is the FoxNews version. It doesn't matter, it is only your choice to pickup the source of information. You can hear and repeat as a parrot what the media is telling you and the great scientists payed by greedy companies or the government, of course scientists that you never have heard before and never did anything, or take some physics and engineering text books and understand, analyze and learn something. Beside this exist pure logic and common sense. If something is not coherent and one fact doesn't match other fact it doesn't matter what even Einstein can tell you on FoxNews it will continue to have no sense. The only conclusion that we can have is or they are only telling us faerie tales or the plant had a complete lack of security and the reactors had a faulty and not secure design. Some facts to meditate: - A steam machine doesn't need electricity to work and cool the steam. A nuclear reactor is nothing more than a steam machine where the coal is replaced by uranium fission. - A nuclear plant generates electricity, if the reactor is so hot then its own electric generator can generate all the electric energy needed to cool the plant and all the functions needed. - If the cooling stopped because lack of electricity due the earthquake and if the core was so hot and continue to generate heat even was stopped then the pressure of steam inside the internal vessel should have exploded the core in less than a hour after the lack of cooling.

"TOKYO (Reuters) – Japanese engineers conceded on Friday that burying a crippled nuclear plant in sand and concrete may be the only way to prevent a catastrophic radiation release, the method used to seal huge leakages from Chernobyl in 1986." Of course that is not Chernobyl again.

lol.... everyone is an expert ;)
