EPR, to the dregs for EDF and Areva?

[Did67]

He stays :

1) that I think like Flytox: between "engineer", we will work out; these covers will not be redone; and the plant will be commissioned ... one day!

2) that the same people will explain to us that this is perfectly certain, that the experts have spoken without compromise; "trust us"

3) that we are incompetent in renewable energies (if Areva has wind turbines in its catalog, it is because they bought the Germans!) And now perfectly ridiculous in nuclear (on the side of Westinghosue or Mitsubishi, we must laugh )!

4) that soon, we will "straighten out", with great redundancies!

5) that there will be some to protest, because, obviously, it will be the fault of ..... the State!

[It is true that EdF had the expertise of "assembler" of such complex projects; Areva was a "boilermaker" from Framatome; you put a temper at the head of one and an "atomic Anne" at the head of the other, and that's what that gives, the ambitions; but they well deserved the retreats -chapeuax, the "tokens" of the board of directors, etc ...]

an article from the world, more provided ... confirms well the risks of cracks feared by ASN, without communicating figures

During the first chemical and mechanical tests on similar parts in late 2014, the engineers noted a high concentration of carbon, reducing the ability of the steel to resist the propagation of cracks. An essential resistance in a boiler subjected to enormous pressures and to violent thermal shocks, specifies the nuclear policeman.

And the funniest!

This uncertainty about the resistance capacities of the tank is all the more worrying since it also concerns the two EPRs built by EDF and its partner China General Nuclear Power Corporation (CGN) on the site of Taïshan, in the Chinese province of Guangdong. .

ASN officials warned their Chinese colleagues of a risk of default, while the first Chinese EPR should be commissioned in 2016. However, ASN indicates that the parts of the Finnish EPR for Olkiluoto, forged in Japan, are not affected by these "anomalies".

So we have plants that will start up with high probability, equipped with questionable Areva kettles.

And the Finnish EPR which will not start with a high probability, is equipped with a good tank ... made by Japanese. Excellent!

[Did67]

Absolutely !

Imagine the proud rooster, with both feet in the shit, singing: "Yes, but we are the nuclear world champions!". It will not take long for a presidential candidate who has ecology in his sights will enchant us with an argument like this ...

Laughter in the farmyard!

an article from the world, no longer supplied ...

Yes, I had shortened it a bit!

The Flamanville EPR tank has also was manufactured by the Japanese (by Japan Steel Works precisely) because there is not (yet) a press in France capable of forging an ingot of 500 tonnes of special steel poured under vacuum to make it a reactor vessel of a single piece, without welds.

http://www.usinenouvelle.com/article/le ... on.N145722 : "Alas, everything is blocked because of a single supplier. For the manufacture of its tank, the EPR needs large components made exclusively by the Japanese JSW"

http://www.world-nuclear-news.org/C-JSW ... 11117.html "JSW…. has supplied the reactor pressure vessels for both the Areva EPRs currently under construction in Finland and France"

https://www.econologie.com/forums/epr-le-fut ... 6-190.html

Today's standards are very strict and the EPR tanks are of much better quality than the tanks of our EDF PWRs from the 70s where there were kilometers of welds.

[Remundo]

the problem is to know if the defect is very serious or not ...

if we have abnormal carbon contents, we could approach locally a cast iron and not a steel ...

no serious figure comes out ...

Le Monde article is in total contradiction with your information

Forged in the Areva factory in Chalon / Saint-Marcel (Saône-et-Loire), the tank is subject to the decree on nuclear pressure equipment which has reinforced technical requirements in this area since 2005. This part must be without default since it is the only one that cannot be changed during the lifetime of an EPR, which will be from sixty to one hundred years

Perhaps the body of the tank was not manufactured by Areva? But the bottom and the cover are made by this factory.

[Remundo]

http://www.lejsl.com/edition-de-chalon/ ... e-de-l-epr
The local newspaper of Châlon sur Saone confirms:

At the end of 2013, the Areva plant in Saint-Marcel delivered the tank body for the future Flamanville EPR (Handle). The caps of the cover and the bottom of the tank, manufactured by Creusot Forge, should follow in a few months for this future nuclear power plant whose delays and additional costs compared to forecasts have already attracted many critics.

Monitoring the construction of these parts involves carrying out tests on samples representative of the composition of the steel, the results of which must be communicated to the Nuclear Safety Authority (ASN). Earlier this week, this body announced that tests carried out in late 2014 by the nuclear group had demonstrated "the presence of an area with a high concentration of carbon and leading to lower mechanical strength values ​​than expected. "

From Chalons sur Saône to Flamanville
Manufactured at the Areva factory in Chalons on
Saône, the steam generators have
traveled 3700 km to reach the coast
Norman. They were routed by
boat to Cherbourg, then placed on
a barge to be transported to
port of Diélette.

Yes, they deliver the tank body made in Japan by JSW and MHI.

From the start of the project in 2004, it was planned that the Japanese JSW and MHI would supply the main components of the EPRs (body, base, cover) until Creusot-Loire was able to manufacture them. This info did not interest anyone and it went unnoticed at the time:

The Creusot-Loire cover of the Flamanville EPR had faults, now it's the bottom ...

AMHA, we want to save time. We are waiting for the Taishan EPR to start and for the Chinese to wipe the plaster ...

[Remundo]

According to the previous link, from the local newspaper of Châlon, the lid and the bottom come out of the Creusot Forge factory

At the end of 2013, the Areva factory in Saint-Marcel delivered the tank body for the future EPR in Flamanville (Manche). The caps of the lid and the bottom of the tank made by Creusot Forge, must follow in a few months for this future central

So I would still be surprised if "everything" came from the Friends of the Rising Sun in the steam generator.
