Tokyo Electric Power Co (TEPCO) is the power company that operates the Japanese sit are nuclear plants in Fukushima Dai Ichi where the explosions occurred and the site Fukushima Daini distant a dozen miles, all totaling ten reactors that supply electricity in Tokyo and its surroundings.
These reactors are boiling water, it is heated by the fission of atoms of the fuel is converted into steam is led directly by a radioactive primary circuit to a power generator, this configuration is completely different from reactors called pressurized water reactors (PWRs) operated in France that have a non-radioactive secondary circuit with a heat exchanger that supplies the turbine generator.
Faced with a succession of disastrous events of natural orders that occurred in Japan following the earthquake and beyond the human tragedy it is essential to go to basics, ie what might mortgaging the future of sustainable living in an area more or less wide, if not in all of Japan and the satellite countries, or worse, a scenario of global environmental disaster ever equaled.
Unfortunately in the case of the Fukushima nuclear site, the "hierarchy disaster" may reach a climax with the reactor 3 to 34 years of age who was responsible for the first time in MOX fuel supplied by AREVA in August 2010.
" The company Tokyo Electric MOX fuel loaded in the old reactor in Fukushima "
"Tokyo Electric Power Co loaded plutonium-uranium mixed oxide fuel Saturday Into a reactor" at its nuclear power plant in Fukushima Prefecture in preparation for The Largest Japanese utility's first plutonium-thermal power generation. The No. 3 reactor at Fukushima No. 1 The Would Be The Third Plant in Japan to Be Used For The so-called Pluthermal generation, to The Only One Among the Three to Have Been Subjected to Treatment With 34 years antiaging sincere icts launch "
" The Tokyo Electric Power Co (TEPCO) has instructed the mixed oxide fuel of plutonium-uranium (MOX) on Saturday in a reactor of the nuclear plant in Fukushima area to the largest electricity generating nuclear reaction produced plutonium in Japan. " The reactor number 3 at the Fukushima No. 1 will be the third in Japan to pass the so called Pluthermal (Plutonium-Thermal) , but the only one among the three to have been subjected to an anti-aging since its activation, because it is 34 years old "
Under section two explicit comments:
"... incompetence in Japan is high at the maximum level, that way she poses a great danger to humanity ".
The second comment was prescient:
" Maybe THEY forgot to tell everyone how they've Determined There Will Never Be Any More Earthquakes. Idiots are Indeed correct. Likely long-term pain for short term gain "
" Maybe they should say how they determined that there would ever earthquake. Say were idiots is correct. There will probably be pain in the long term for gains in the short term "
« Lors de l’activation la compagnie a indiqué qu’elle a eu des difficultés à démarrer le réacteur n ° 3 de la centrale située à Fukushima et a reporté l’activation initialement prévue pour vendredi soir. » « The company said the alarm light indicating the conditions of the pipe valve for the emergency core cooling system did not function properly. » « La compagnie a déclaré que le voyant d’alarme indiquant des conditions anormales de la vanne de commande des tuyaux pour le système de refroidissement d’urgence ne fonctionnait pas correctement. »
En mars 2011, aux vues des événements, this information takes on another dimension.
FUKUSHIMA ALERT PLUTONIUM
The MOX for "Mixed Oxides" is a highly toxic and hazardous fuel composed of about 6-7% plutonium dioxide recovered "reprocessing" the fuel spent nuclear which is mixed with depleted uranium dioxide nine. MOX between more easily melted than conventional fuels, it is used in 20 of the French nuclear reactors. The major problem is that the plutonium MOX fuel is highly toxic in the short and long term. Voice-air, an estimated amount of the order of ten milligrams causes the death of a person who inhaled at once plutonium oxides. The dose-effect relationship has demonstrated a threshold of appearance of lung tumors in a dose millesimal, over a significant portion passes from the lungs to inhaled blood which disseminates to other organs (lymph nodes, liver, etc ... ), more or less quickly depending on the size of the particles, leading to cancers.
According isotropic composition is capable of infecting large masses of sea water for more than one century is at best a half-life and at worst, for 240 centuries! Plutonium is produced by the cores of nuclear reactors under the influence of neutron flux, is not only part of the elements having a very high radiotoxicity, but all the isotopes and other compounds from plutonium are also classified very toxic and radioactive ( see Wikipedia ). What makes it particularly dangerous plutonium is among other things, the high energy of its emission of alpha particles with a value of 5 MeV compared to 0.02 MeV tritium.
According to the information last minute, the old Unit 3 of Fukushima Dai Ichi came partially molten, a risk of disintegration is an assumption that is not excluded, but in the realm of probability. This would result in a massive release into the environment and atmosphere of highly radio-toxic particles.
The worst being that the reactor 3 with 784 MW is 1.5 times more powerful than a 460 MW reactor loaded with enriched uranium, which means that its loading fuel into plutonium, therefore, is much more consistent with a parallel heat off at much larger to handle.
But there is worse than worst-case scenario in a reactor with 3 of Fukushima: The MOX fuel is a mixture has a melting point much lower than other fuels are considered classic, consequently, in configuration accidental risk as being told to criticality, ie the start of a uncontrollable nuclear chain reaction is much more important. Other problems collateral aggravate the situation for "Fire Services" who sacrifice themselves to avoid water does not melt, because the water mixed with boron is used to mitigate the effects of heating of the radioactivity (absorbs neutrons) is less effective with MOX.
terms of numbers, they are frightening, the mass of plutonium in the reactor 3 of the nuclear site Fukushima Dai Ichi is significant, it amounts to several hundred kilograms, an unprecedented global catastrophe, created by man, is therefore possible for the first time in the history of mankind.
Meanwhile, even zapping no way to escape, on television shows a tandem consisting of a man who "knows everything" called Eric Besson, accompanied by stainless NKM who knows nothing but talk a lot without saying anything, n 'obviously not evoke the MOX , but are the kings of intoxication. With the French AREVA MOX in Japan, it is better now adopt a low profile! This tandem unreal and they want reassurance pandering to anyone who will listen that this is not the party that has failed in nuclear reactors of the plant in Fukushima Dai Ichi, but the pipes, that is to say systems cooling and relief included the tsunami, it is highly inconceivable in France, etc ... Some issues of risk from major natural disasters are inherently unmanageable, therefore manage a nuclear power plant with zero risk is impossible on this postulate and current forces, people in responsible positions should draw the appropriate conclusions. Andreas Heumann, a researcher at the CNRS said "The problem with nuclear is that this technology is not controllable, we can get to keep control under normal conditions. But there are so of Abnormal Situations qui peuvent survenir ".
