Fukushima nuclear power station finds plutonium is let out and does not deal with and have endless trouble in time
No matter how much plutonium let out is, it is very troublesome to deal with. Should take the fuel away in time excellently now, otherwise have endless trouble
Beijing time before dawn on March 29, it is verified that International Atomic Energy Agency releases the announcement, Japan finds micro- radioactive element plutonium in the soil sample near Fukushima first nuclear power station.
The announcement of International Atomic Energy Agency has not explained which kind of plutonium Japan detects, and the intersection of nuclear power station and common the intersection of isotope and plutonium - 239 under reactor, reach 2 Wan for many years half-life, namely half of its decays, radiation risk reduces half the time to need More than 2 ten thousand years. Because the toxicity of plutonium is great, half-life is relatively long, this news caused people worrying more to Fukushima nuclear power station.
The academy of sciences of Chinese atomic energy takes care of the loyal luxuriant researcher to tell the new reporter of the wealth, plutonium is that the nuclear fuel must emerge in the course of reacting, have already measured the radioactive iodine before this, has proved the damage takes place in the excellent outer cover of fuel, this means that leaking must contain plutonium in the material. Another respect, plutonium compares with iodine, flowability is relatively bad, the iodine is volatile, to the air middle-distance race, and plutonium is that the advanced person enters water, enter soil again, it is just a time question to measure to plutonium.
Radiation, Center for Disease Prevention and Control of China, protect with the intersection of nuclear safety and medical science wishing researcher, the people of Chinese, say to the intersection of the wealth and new reporter, plutonium is a fissile product, it is not natural, it is artificial. But he says, though plutonium has a radioactive one, half-life is very long, but there is very few quantity measured in the environment at present, what danger will produce to the human body not . In addition, because the reactor has already been stopped piling, there should not be a large amount of plutonium to let out.
Certainly, Gu ZhongMao points out, no matter how much plutonium that lets out is, it is very troublesome to deal with. Japan is still devoted to cooling in situ at present, another scheme is to pile and deal with one like that as cutting to the promise Pele, but its cost and cost are extremely high.
" Leakage of plutonium begin just now, should wonderful to take away fuel in time. " L Gu ZhongMao says, " If adopt finally one piles and deals with but not takes away plutonium, plutonium will still pollute the groundwater, have endless trouble. "
International Atomic Energy Agency claims, micro- plutonium appears in the soil, it is not a rare thing, because plutonium will float and fall in the soil in all parts of the world after the nuclear test. However, this organization quotes Tokyo Utilities Electric Co. to say, according to composition of isotope found in the soil near Fukushima first nuclear power station plutonium, should let out from the nuclear power station reactor. And the content of plutonium in its soil, has not exceeded this natural bottom level that Japanese Ministry of Education has monitored in the past 30 years yet at present.
