Fukushima disaster is worse than Chernobyl

Why the Fukushima disaster is worse than Chernobyl

Japan has been slow to admit the scale of the meltdown. But now the truth is coming out. David McNeill reports from Soma City

Yoshio Ichida is recalling the worst day of his 53 years: 11 March, when the sea swallowed up his home and killed his friends. The Fukushima fisherman was in the bath when the huge quake hit and barely made it to the open sea in his boat in the 40 minutes before the 15-metre tsunami that followed. When he got back to port, his neighbourhood and nearly everything else was gone. "Nobody can remember anything like this," he says.

Now living in a refugee centre in the ruined coastal city of Soma, Mr Ichida has mourned the 100 local fishermen killed in the disaster and is trying to rebuild his life with his colleagues. Every morning, they arrive at the ruined fisheries co-operative building in Soma port and prepare for work. Then they stare out at the irradiated sea, and wait. "Some day we know we'll be allowed to fish again. We all want to believe that."

This nation has recovered from worse natural – and manmade – catastrophes. But it is the triple meltdown and its aftermath at the Fukushima nuclear power plant 40km down the coast from Soma that has elevated Japan into unknown, and unknowable, terrain. Across the northeast, millions of people are living with its consequences and searching for a consensus on a safe radiation level that does not exist. Experts give bewilderingly different assessments of its dangers.

Some scientists say Fukushima is worse than the 1986 Chernobyl accident, with which it shares a maximum level-7 rating on the sliding scale of nuclear disasters. One of the most prominent of them is Dr Helen Caldicott, an Australian physician and long time anti-nuclear activist who warns of "horrors to come" in Fukushima.

Chris Busby, a professor at the University of Ulster known for his alarmist views, generated controversy during a Japan visit last month when he said the disaster would result in more than 1 million deaths. "Fukushima is still boiling its radionuclides all over Japan," he said. "Chernobyl went up in one go. So Fukushima is worse."

On the other side of the nuclear fence are the industry friendly scientists who insist that the crisis is under control and radiation levels are mostly safe. "I believe the government and Tokyo Electric Power [Tepco, the plant's operator] are doing their best," said Naoto Sekimura, vice-dean of the Graduate School of Engineering at the University of Tokyo. Mr Sekimura initially advised residents near the plant that a radioactive disaster was "unlikely" and that they should stay "calm", an assessment he has since had to reverse.

Slowly, steadily, and often well behind the curve, the government has worsened its prognosis of the disaster. Last Friday, scientists affiliated with the Nuclear and Industrial Safety Agency said the plant had released 15,000 terabecquerels of cancer-causing Cesium, equivalent to about 168 times the 1945 atomic bombing of Hiroshima, the event that ushered in the nuclear age. (Professor Busby says the release is at least 72,000 times worse than Hiroshima).

Caught in a blizzard of often conflicting information, many Japanese instinctively grope for the beacons they know. Mr Ichida and his colleagues say they no longer trust the nuclear industry or the officials who assured them the Fukushima plant was safe. But they have faith in government radiation testing and believe they will soon be allowed back to sea.

That's a mistake, say sceptics, who note a consistent pattern of official lying, foot-dragging and concealment. Last week, officials finally admitted something long argued by its critics: that thousands of people with homes near the crippled nuclear plant may not be able to return for a generation or more. "We can't rule out the possibility that there will be some areas where it will be hard for residents to return to their homes for a long time," said Yukio Edano, the government's top government spokesman. "We are very sorry."

Last Friday, hundreds of former residents from Futaba and Okuma, the towns nearest the plant, were allowed to visit their homes – perhaps for the last time – to pick up belongings. Wearing masks and radiation suits, they drove through the 20km contaminated zone around the plant, where hundreds of animals have died and rotted in the sun, to find kitchens and living rooms partly reclaimed by nature. "It's hard to believe we ever lived here," one former resident told NHK.

Several other areas northwest of the plant have become atomic ghost towns after being ordered to evacuate – too late, say many residents, who believe they absorbed dangerous quantities of radiation in the weeks after the accident. "We've no idea when we can come back," says Katsuzo Shoji, who farmed rice and cabbages and kept a small herd of cattle near Iitate, a picturesque village about 40km from the plant.

Although it is outside the exclusion zone, the village's mountainous topography meant radiation, carried by wind and rain, lingered, poisoning crops, water and school playgrounds.

The young, the wealthy, mothers and pregnant women left for Tokyo or elsewhere. Most of the remaining 6000 people have since evacuated, after the government accepted that safe radiation limits had been exceeded.

Mr Shoji, 75, went from shock to rage, then despair when the government told him he would have to destroy his vegetables, kill his six cows and move with his wife Fumi, 73, to an apartment in Koriyama, about 20km away. "We've heard five, maybe 10 years but some say that's far too optimistic," he says, crying. "Maybe I'll be able to come home to die." He was given initial compensation of one million yen (£7,900) by Tepco, topped up with 350,000 yen from the government.

It is the fate of people outside the evacuation zones, however, that causes the most bitter controversy. Parents in Fukushima City, 63km from the plant, have banded together to demand that the government do more to protect about 100,000 children. Schools have banned soccer and other outdoor sports. Windows are kept closed. "We've just been left to fend for ourselves," says Machiko Sato, a grandmother who lives in the city. "It makes me so angry."

Many parents have already sent their children to live with relatives or friends hundreds of kilometres away. Some want the government to evacuate the entire two million population of Fukushima Prefecture. "They're demanding the right to be able to evacuate," says anti-nuclear activist Aileen Mioko Smith, who works with the parents. "In other words, if they evacuate they want the government to support them."

So far, at least, the authorities say that is not necessary. The official line is that the accident at the plant is winding down and radiation levels outside of the exclusion zone and designated "hot spots" are safe.

But many experts warn that the crisis is just beginning. Professor Tim Mousseau, a biological scientist who has spent more than a decade researching the genetic impact of radiation around Chernobyl, says he worries that many people in Fukushima are "burying their heads in the sand." His Chernobyl research concluded that biodiversity and the numbers of insects and spiders had shrunk inside the irradiated zone, and the bird population showed evidence of genetic defects, including smaller brain sizes.

"The truth is that we don't have sufficient data to provide accurate information on the long-term impact," he says. "What we can say, though, is that there are very likely to be very significant long-term health impact from prolonged exposure."

In Soma, Mr Ichida says all the talk about radiation is confusing. "All we want to do is get back to work. There are many different ways to die, and having nothing to do is one of them."

Economic cost
Fukushima: Japan has estimated it will cost as much as £188bn to rebuild following the earthquake, tsunami and nuclear crisis.
Chernobyl There are a number of estimates of the economic impact, but thetotal cost is thought to be about £144bn.

Safety
Fukushima: workers are allowed to operate in the crippled plant up to a dose of 250mSv (millisieverts).
Chernobyl: People exposed to 350mSv were relocated. In most countries the maximum annual dosage for a worker is 20mSv. The allowed dose for someone living close to a nuclear plant is 1mSv a year.

Death toll
Fukushima: Two workers died inside the plant. Some scientists predict that one million lives will be lost to cancer.
Chernobyl: It is difficult to say how many people died on the day of the disaster because of state security, but Greenpeace estimates that 200,000 have died from radiation-linked cancers in the 25 years since the accident.

Exclusion zone
Fukushima: Tokyo initially ordered a 20km radius exclusion zone around the plant
Chernobyl: The initial radius of the Chernobyl zone was set at 30km – 25 years later it is still largely in place.

Compensation
Fukushima: Tepco's share price has collapsed since the disaster largely because of the amount it will need to pay out, about £10,000 a person
Chernobyl: Not a lot. It has been reported that Armenian victims of the disaster were offered about £6 each in 1986

Aid
Fukushima: The UN's Office for the Co-ordination of Humanitarian Affairs reported bilateral aid worth $95m
Chernobyl: 12 years after the disaster, the then Ukrainian president, Leonid Kuchma, complained that his country was still waiting for international help.

Nucleare: le verità nascoste

Nucleare: le verità nascoste

I grandi perchè dell'era nucleare

Leggo esterrefatto su IL GIORNALE del 12.5.11 che la Fondazione Veronesi, creatura del Professore, sta organizzando degli incontri nelle scuole, detti "Giorni della Scienza", per spiegare ai nostri figli l'abc del nucleare, "l'energia del futuro, pulita, non inquinante, non comportante pericoli per la salute".

Capisco che il Veronesi è membro del Comitato scientifico dell'IIT, Istituto Italiano Tecnologia, che ha finanziato il suo IEO, Istituto Italiano Oncologia, che necessita di tanti malati di cancro per curarli a dovere... E i malati di cancro, radioindotto dalle continue emissioni radioattive stocastiche dalle centrali nucleari, sono in drammatico aumento, soprattutto leucemìe nei bambini, i più radiosensibili, cui seguirà l'escalation dei cancri negli adulti.

Gioverà ripetere ai colleghi che le centrali nucleari, anche della più recente generazione, sono dei colabrodo che scaricano continuamente cancrìgene dosi radioattive stocastiche (v. il mio Saggio 12.10.09 nel mio sito www.marcomarotta.it, alla voce Altri contributi, v. anche www.youtube.com/watch?v=RiJESPdLXpA), che il Veronesi tace ostinatamente, pur essendo stato edotto dai Rapporti dell'ENEA, quale ex Ministro della Salute, che per km dalle centrali nucleari risultano in pericolo di cancerizzazione collettiva le popolazioni per radiocontaminazione tossica di tutte le produzioni alimentari!

Visto che il Veronesi contravvenendo alle norme del Codice Deontologico promuove Giorni della Scienza per disinformare i colleghi meno edotti e meno attenti, invito gli Ordini e i medici in indirizzo ad aggiornarsi (Art. 16 Codice Deontologico 08) sul vitale tema leggendo il mio I GRANDI PERCHE' DELL'ERA NUCLEARE ("degno di alta segnalazione", ASL Besana) acquistabile con pochi € anche online ( info@hoepli.it, e.carraro@hoepli.it), ove è spiegata e documentata l'induzione dei mutamenti climatici, delle rovinose alluvioni, del buco dell'Ozono, del riscaldamento dell'atmosfera... ad opera della radioattività scaricata e cumulata nell'ambiente.

"Se non cambiate modo di pensare la radioattività scaricata di continuo in atmosfera provocherà la fine di ogni forma di vita sulla Terra!". Così ci disse 60 anni fa Albert Einstein, il sommo scienziato venuto dal futuro per sollecitarci alla pronta chiusura di tutte le centrali nucleari nel mondo.

A quell'appello si unisce compatta la Scienza Medica Italiana.

Fukushima: Japan Radiation Spreads Worldwide

Fukushima: Japan Radiation

Spreads Worldwide

by Arnie Gundersen

AUGUST 24, 2011

New Data Supports Previous Fairewinds Analysis, as Contamination Spreads in Japan and Worldwide


Newly released neutron data from three University of California San Diego scientists confirms Fairewinds' April analysis that the nuclear core at Fukushima Daiichi turned on and off after TEPCO claimed its reactors had been shutdown. This periodic nuclear chain reaction (inadvertent criticality) continued to contaminate the surrounding environment and upper atmosphere with large doses of radioactivity.

In a second area of concern, Fairewinds disagrees the NRC's latest report claiming that all Fukushima spent fuel pools had no problems following the earthquake. In a new revelation, the NRC claims that the plutonium found more than 1 mile offsite actually came from inside the nuclear reactors. If such a statement were true, it indicates that the nuclear power plant containments failed and were breached with debris landing far from the power plants themselves. Such a failure of the containment system certainly necessitates a complete review of all US reactor containment design and industry assurances that containments will hold in radioactivity in the event of a nuclear accident. The evidence Fairewindsreviewed to date continues to support its April analysis that the detonation in the Unit 3 Spent Fuel pool was the cause of plutonium found off site.

Third, the burning of radioactive materials (building materials, trees, lawn grass, rice straw) by the Japanese government will cause radioactive Cesium to spread even further into areas within Japan that have been previously clean, and across the Pacific Ocean to North America.

And finally, the Japanese government has yet to grasp the severity of the contamination within Japan, and therefore has not developed a coherent plan mitigate the accident and remediate the environment. Without a cohesive plan to deal with this ongoing problem of large scale radioactive contamination, the radioactivity will continue to spread throughout Japan and around the globe further exacerbating the problem and raising costs astronomically.

Fukushima robot operator publishes tell-all diaries

Japan: Fukushima robot operator publishes tell-all diaries and videos, now offline

IEEE Spectrum reports on a pseudonymous/anonymous tell-all blog written by a Fukushima Daiichi cleanup worker whose job is to operate robots (actually, iRobot robots) at the tsunami- and quake-damaged, radioactivity-spewing power plant in Japan. The IEEE Spectrum item includes complete English language translations of some of the whistleblower's blog posts, all of which are now offline. This is a must-read.

The worker known as "S.H." wrote about the hazardous, chaotic, high-radiation environment in which he and other workers deploy remote-controlled robots "to assist with efforts to further stabilize and shut down the plant’s four troubled reactors." Snip from IEEE Spectrum:

The blog posts, which have recently been deleted, depict the operators’ extensive robot training exercises, as well actual missions, including surveying damage and contamination in and around the reactors and improvising a robotic vacuum to suck up radioactive dust. The author, who goes by the initials S.H., also used the blog to vent his frustrations with inept supervisors and unreasonable schedules, though he maintains a sense of humor, describing in one post how he punched a hole on a wall while driving a robot and, in another entry, how a drunken worker slept in his room by mistake.

The material also raises questions about whether Tokyo Electric Power Co. (TEPCO), the plant’s owner, is acting with adequate speed and providing enough robots and supporting resources for the robot teams. It's ironic that, although the robots are remote controlled, the operators still have to work close to the highly damaged and radioactive reactors. There is no communications infrastructure, combining wired and wireless capabilities, that would allow the operators to do their work from a safer location.

Other problems, described by S.H. in some entries, include a lack of coordination and, on at least one occasion, neglect for the workers’ safety. In one incident, a technician not part of the robot team recklessly put a robotic mission in jeopardy, driving a truck over a tether and nearly severing the connection between the robot and the operators. S.H also reports that one day his personal dosimeter began sounding an alarm and wouldn’t stop; when he asked a radiation personnel in charge about it, he was told ignore it and continue working.

The contents of the blog are available on Google's cache. A Japanese researcher has also republished some of the posts on his site. "S.H." also published about an hour's worth of video on YouTube documenting training exercises with the iRobot PackBot and Warriorrobots, but the videos have since been made private.

"While the videos were publicly available, I used a program to capture snippets, which I used to put together my own video," writes IEEE Spectrum's Erico Guizzo. "We believe we’re making fair use of the snippets, using them as documentation of the training process, which is a newsworthy event. Note that our video shows only brief moments of what might have been many hours of training and it probably doesn't reflect the operators' current skill levels. The video also includes some candid moments, such as when a worker takes a ride on a Warrior robot."

Fukushima: tragédie en sous-sol

Fukushima: tragédie en sous-sol

par olivier cabanel

Plus de 5 mois se sont écoulés depuis la catastrophe de Fukushima, et les gouvernements, comme les lobbys n’en finissent pas d’agiter des écrans de fumée pour tenter de nous masquer une réalité de plus en plus préoccupante.

Dans une courte vidéo consacrée à Tchernobyl, il est intéressant de faire un parallèle avec la situation qui se déroule à Fukushima.

On y entend Giscard affirmer à plusieurs reprises : « je crois tout d’abord qu’il faut rassurer les Français (…) il y a un taux de radioactivité qui est faible et qui ne peut avoir de conséquences pour la santé de la population ».

Il évoque au sujet de la centrale de Tchernobyl « une technologie rustique » ce qui n’est pas sans nous rappeler la déclaration de Nicolas Sarközi, lors de sa visite au Japon, vantant les mérites de l’EPR, affirmant qu’il est bien plus sur que les centrales japonaises.

« Si on a perdu des marchés et des appels d’offres, c’est parce qu’on est les plus chers. Et si on est les plus chers, c’est parce qu’on est les plus surs » a-t-il déclaré 3 jours après la catastrophe de Fukushima. lien

Ce qui dénote d’un sérieux manque de diplomatie, et qui de plus est totalement erroné.

Comme le dit Marc Aroman du réseau « sortir du nucléaire » : « les centrales japonaises ont 5 barrières de confinement contre 3 en France (…) les entreprises qui ont construit les centrales nucléaires ont une avance nettement supérieure sur les technologies antisismiques »

Opale Crivello porte parole de cette organisation ajoute : « Fessenheim (et d’autres centrales françaises) ont un problème au niveau des coussinets des groupes électrogènes, sujets à une usure prématurée. En cas de coupure électrique, si ceux-ci ne tiennent pas, les conséquences pourraient être catastrophiques, une fusion partielle du cœur est possible ». lien

Et Jean Paul Biberian, ingénieur en Physique Nucléaire et Electronique, maitre de conférences de physique à la faculté des sciences de Luminy de conclure : « Personne n’est en mesure d’exclure l’hypothèse d’un accident (…) les centrales françaises ne seront jamais totalement sures (…) ne continuons pas le Concorde nucléaire, faisons l’Airbus des nouvelles énergies ». lien

On sait que ni le dernier « fleuron » l’EPR, ni les autres centrales, ou l’usine de la Hague, ne résisteront au crash d’un avion de ligne. lien

Mais revenons à Tchernobyl.

C’est ensuite Alain Madelin, alors ministre de l’industrie, des PTT, et du tourisme, qui prend la parole :

« Il faut dans cette affaire du nucléaire jouer complètement le jeu de la transparence (!) On s’aperçoit qu’il n’y a pas eu de maillon faible dans la sécurité des français, il y a eu un maillon faible dans la procédure de communication (…) je tiens à vous dire qu’il n’y a aucun problème de sécurité en France, aucun (…) nous n’avons rien à cacher, nous mettons cartes sur table (…) aucun risque sanitaire (…) aucune inquiétude à avoir ». puis on entend le Professeur Pellerin, responsable du SCPRI(service de protection contre les rayonnements ionisants) : « il s’agit d’une radioactivité qui est notable mais qui ne présente aucun inconvénient sur la santé publique, seulement on a fait tellement de catastrophisme sur le plan du nucléaire qu’on risque de déclencher des paniques (…) ça ne menace personne actuellement sauf peut-être dans le voisinage immédiat de l’usine, et encore c’est surtout dans l’usine que je pense que les Russes ont admis qu’il y avait des personnes lésées »

A la question « est-ce qu’on a constaté quelque chose au dessus de la France ? » il répondait avec assurance et sérénité :

« Non, parce que les vents ne vont pas dans cette direction là, les vents tournent dans le sens inverse des aiguilles d’une montre, il y a pas lieu du tout de s’inquiéter, c’est sans aucun dangers pour la santé publique »

Quand à la ministre française de la santé de l’époque, elle prenait la défense du professeurPellerin en disant : « ils ont travaillé comme des bêtes pendant un mois, seulement ce n’est pas leur métier de faire de la communication »

Alors on se demande ce que le professeur Pellerin faisait sur les plateaux de télévision martelant d’énormes mensonges avec la plus grande conviction ?

Dans ce court documentaire, une experte physicienne russe conclut : « Le plus dangereux isotope sorti du réacteur de Tchernobyl, ce n’est ni le césium, ni le plutonium, mais le mensonge (…) un mensonge qui s’est propagé comme la radioactivité dans notre pays et dans le monde entier ». lien

Mais revenons à Fukushima.

Les coriums des 3 réacteurs sont manifestement partis jouer les « filles de l’air », et pour bien en comprendre le danger, il faut savoir qu’il peut atteindre 3000°C (la lave d’un volcan est en moyenne à 1000°C), faisant fondre la plupart des matériaux qu’il rencontre, détruisant tout sur son passage : il émet tellement de radioactivité (28 térabecquerels par kilo) que personne ne peut s’en approcher sans trouver la mort en quelques secondes.

Il faudra de longs mois pour amener la température du corium « à froid ». (À Tchernobyl, il a fallu entre 6 et 7 mois, mais 18 ans après la catastrophe, on mesurait encore une température de 36° C à proximité du combustible fondu).

D’après de nombreux experts, la cuve du réacteur n°1 a été traversée dès le soir du 11 mars, et elle a traversé la dalle de 8 mètres d’épaisseur dès le 12 mars. lien

Sa vitesse de progression est inconnue, mais doit être assez rapide, et s’il s’est rassemblé, il a formé un puits d’environ 0,80cm descendant à la verticale, à moins qu’il ne se soit dispersé s’infiltrant dans des failles rocheuses, se divisant en multiples tentacules, ce qui lui ferait perdre de sa puissance.

Les experts pensent que le pire des cas serait que le corium s’enferme dans le béton, ou dans le sol, ce qui lui permettrait de conserver son intégrité, augmentant le nombre de neutrons récupérés, le rendant inaccessible, et donc quasi impossible à refroidir.

Un autre risque existe, en cas de Melt-through, (syndrome chinois) il peut fragiliser les fondations des réacteurs, provoquant des failles supplémentaires dans le béton des constructions, laissant s’échapper les milliers de litres d’eau encore présente dans la centrale et menaçant la stabilité des bâtiments. lien

Cerise sur le gâteau, comme la centrale n’est qu’à 200 mètres de l’Océan, si le corium rencontre la nappe aquifère en relation avec la mer, la contamination pourrait durer des dizaines d’années, polluant pour longtemps l’ensemble du littoral oriental du Japon.

Les trois coriums de Fukushima représentent 257 tonnes émettant donc plus de 7 millionsde terabecquerels. lien. (Celui de Tchernobyl était estimé à un maximum de 80 tonnes).

Il faut aussi se souvenir que le corium du réacteur n°3 contient 300 kg de plutonium. lien

Le 4 aout, (lien) la caméra de surveillance a filmé un énorme dégagement de fumée, et de lumières intenses, puis la même situation s’est produite le 13 aout (lien) le 14 aout (lien) et le18 aout (lien) (à partir d’une 1’10’’)

Pour beaucoup d’observateurs, il est évident que ces dégagements de vapeur radioactive et de lumières intenses sont provoqués par le corium, chaque fois qu’il rencontre de l’eau. (lien)

Dans ces dégagements de vapeur, on trouve du Neptunium, ce qui est la preuve d’une réaction nucléaire en cours, ce Neptunium-239 a une période de 2,4 jours, et se transforme enPlutonium 239, d’où le fort dégagement de chaleur, lorsque ces matières radioactives atteignent des poches d’eau. lien

Un ouvrier de Fukushima témoigne :

« Des vapeurs massives sortent des fissures de la terre (…) et il semble que la réaction nucléaire arrive du sous-sol. Nous évacuons : prenez garde à la direction du vent (…) nous avons peur ! ». lien

Un autre ouvrier ajoute :

« Prés des réacteurs, il y a beaucoup de fissures dans la terre, la vapeur sort de la, et nous avons découvert 10Sv/h à 6 endroits différents, malgré les annonces du gouvernement ». lien

Alors, lorsque ces jets de vapeur se produisent, les ouvriers sont obligés d’évacuer les lieux, pour échapper au danger radioactif. lien

Paul Gunter évoquant le syndrome chinois, déclare : « 1000 rems sortent de ces fissures (500 rems c’est la dose mortelle) (…) la dose maximale pour le public c’est 100 millirems par an, et là, c’est 1 million de millirems par heure ! Ce sont des doses létales qui sortent du sol.

Ils cherchent à contenir cet accident en construisant des tentes par-dessus les réacteurs, ce qui est un peu absurde et montre qu’on est à un point où on emploie des mesures désespérées.

Mais maintenant la vapeur radioactive remonte du sol par des fissures autour des constructions, ce qui signifie que cet accident est maintenant clairement, sérieusement, bien plus hors de contrôle que ce qu’on veut bien admettre ». vidéo

Pas étonnant dès lors qu’avec les quantités de radioactivité que délivrent chaque jour depuis plus de 5 mois les 3 réacteurs en fusion de Fukushima, les médecins aient détecté de l’iode radioactif dans les tyroïdes de nombreux enfants Japonais. lien

Devant cette situation ingérable, le gouvernement Japonais veut manier une fois de plus la censure, et prépare une révision de la constitution visant à limiter le droit d’expression en cas de catastrophe naturelle. lien

La désinformation continue de plus belle, comme par exemple ces « scientifiques » affirmant que l’on peut boire du plutonium sans danger. lien

Pourtant chacun sait qu’un microgramme de plutonium inhalé peut tuer un être humain en moins de 30 jours. lien

Alors que certains n’hésitent plus à évoquer un génocide (lien) ils sont de plus en plus nombreux à réclamer l’évacuation du Japon. lien

Pour l’expert Christopher Busby, en terme de taux de radioactivité, la situation dans les rues de Tokyo est comparable à celle de Tchernobyl. lien

Mais le silence médiatique mondial continue, puisqu’après le nouveau séisme d’une force de 6,8qui s’est produit le 19 aout, on pouvait entendre sur l’antenne d’Europe 1, et ailleurs, que cela n’avait pas eu d’incidence sur la centrale nucléaire. lien

Donc, tout va bien…

Car comme dit mon vieil ami africain :

« Le malheur peut être un pas vers le bonheur ».
