It would be possible for terrorists to be hired on a temporary basis (up to 1 / 3 from the strength of the plant!) And to place explosives at key points, as long as this would not lead to the explosion of the containment, but already a hell of a mess!

Frankly, the interim terrorist, for me who was EDF provider in Chinon and Tricastin I do not see how it would be possible ...

All this staff is registered by the gendarmerie at the national level and was the subject of a personal investigation. A stranger does not enter unless special permission.

You deposit your ID card at the reception of the plant and you can then see his name, the name of the company and the place where we work displayed on video screens throughout the plant. We know who does what. At the limit, everyone knows when we will piss ... (The interest is that we can learn that we have a friend on the site and we can go to drink a beer.)

Enter explosives? How? There is a search, the flight cases are opened.

You have to know the "key points" otherwise you risk blowing the toilet hose.

Then, these personnel intervene during the maintenance operations, when the reactor is stopped.

Etc. ..

And that was before the events of 11 September 2001. Since then, security has been further strengthened.

The only possibility is the suicide bombing with a truck loaded with explosives and especially incendiary products targeting auxiliaries and cooling circuits. Highly unlikely, fortunately.

In its 2013 report on the safety of EDF power plants, IRSN points to a growing recourse to non-compliant equipment and a breach of maintenance rules.

No need for terrorists ...

All Japanese reactors have a containment chamber, very thick, because of the seismic risk.

At Fukushima Daiichi, the raft (20) under the reactor is 8 meters thick. The containment enclosure makes 1,90 meter thick.

Even without reactor fusion, the primary circuit of a reactor leaks continuously. At EDF, it is estimated that it is not necessary to stop the reactor to repair as long as it does not exceed 200 liters per hour. A network of drains collects these waters, stores them, then reinjects them into the primary circuit if necessary. Otherwise, they are thrown back into the Seine or the Rhone after diluting them ...

Dramatic this photo of Science & Avenir! According to the inscriptions on the grave, the dates of death are earlier than that of the Fukushima disaster! : Cheesy: : Lol:

"hei sei ni ju", ie year 20 (平 成 二十) of the Heisei era started in 1989 (year 1 when Akihito became emperor) so in 2008!

The radioactivity would have retroactive effects because this lady collects on the grave of a deceased ... in 2008! Either three years before the disaster ... : Shock: : Cheesy:

Because you see what is written on the stone you?

If it is the inscription on the wooden cross in the foreground, it seems to me that it is not the grave concerned ...

The Japanese are Buddhists. The tombstones do not give the date of death. There is just the name of the deceased.

It is therefore not a cross but a "sotoba", a sort of wooden pallet which bears the name of the deceased in the afterlife and sometimes a date. There are often inscriptions on both sides.

The sotoba is laid rear the tombstone. The 3 sotobas we see in the photo are therefore those of the grave concerned since there are no others.

Sotoba or gorinsotoba is the stupa of Buddhists:

Regarding the substance, you should know that it is a very common practice, in the press, to illustrate articles with a photo agency news sorted with more or less happiness ...

On subjects that you know well, you will frequently see this kind of bugs! Photos illustrating "intensive productive agriculture" with machines that we no longer manufacture, etc ...

This does not detract from the quality or defects of the article (editorial)! I did not read it.

So, rather than "dramatic", I would rather say that it is a poorly chosen photo, a "stupidity" ... For the article, you have to see the bottom!
