The News That Matters about the Nuclear Industry

Areva factory for nuclear parts gets poor report from regulator

ill-equipped to make nuclear parts – French watchdog, Reuters, 

 Creusot Forge machinery inadequate for making huge parts

* Areva stopped commercial production at factory last year

* Areva wants to restart plant this summer

* Nuclear watchdog must give permission for restart

* Critics say oversight of French nuclear industry needs review

By Geert De Clercq PARIS, March 16 Creusot Forge, a supplier of nuclear plants around the world owned by France’s Areva , is under investigation for making substandard parts and falsifying documents.

Now, France’s nuclear regulator says machinery at the plant, which was shut for commercial production last year, is not up to the job. n an interview, Remy Catteau, the head of nuclear equipment at the ASN (Nuclear Safety Authority), said that an inspection of the plant late last year showed that it did not have the right equipment to produce the parts for the nuclear reactors. “Creusot Forge is at the limit of its technical capacity. The tools at its disposal are not adequate to manufacture such huge components. In such a situation, errors are made,” Catteau told Reuters by telephone.

“The inspection brought to light the fact that the safety culture in the plant is not sufficient to produce nuclear components.”

The disclosure adds to the problems of Areva, once the world’s biggest nuclear company, which owns Creusot Forge.

Areva shut the factory after it found that manufacturing documents at the plant may have been falsified over some 40 years and parts made by the foundry did not meet specifications.

Authorities around the world have checked the nuclear reactors using the parts. Two reactors in France – Fessenheim 2 and Gravelines 5 – were shut after the checks due to safety concerns.

The investigation by the regulator is ongoing but Areva hopes to restart production at the factory this summer, if ASN allows it……

INSPECTIONS

Precision is critical when making parts such as containment vessels, which are huge steel cylinders that house the reactor core and control rods.

Creusot Forge made the vessel lid and bottom for the Flamanville 3 EPR reactor under construction in western France. But at the end of 2014, Areva discovered excessive carbon concentrations in those components, which weaken the steel.

“For Flamanville 3, the equipment was at its limit, there was no margin for error,” Catteau said.

Flamanville’s future is now uncertain. The ASN will rule by the summer whether the new reactor can go into operation by 2018, despite those weak spots. A red light would lead to years of further delays for Areva and its customer EDF.

Regulators from the U.S., Britain, China and other countries are also looking into quality and manufacturing issues at the Creusot Forge foundry in eastern France after Areva unearthed the false manufacturing documentation from the 1965-2013 period.

“One of the ways to resolve problems was to hide things, and that was the wrong way,” Catteau said……..

Areva is being restructured and recapitalized with help from the French state after years of losses wiped out its equity. It lost 665 million euros ($702 million) last year, 2.04 billion euros in 2015 and 4.83 billion euros in 2014.

Critics of France’s nuclear energy establishment say the problems at Creusot Forge prove that oversight of the whole industry, including the ASN, needs an overhaul.

World Nuclear Industry Status Report author Mycle Schneider said France’s parliament should task independent experts with an inquiry, but he does not see the political will for that.

“The entire chain of responsibility has failed, from Areva to its client EDF and the ASN. I don’t see an initiative yet that addresses the entire scope of the problem,” Schneider said. ($1 = 0.9426 euros) (Editing by Anna Willard) http://www.reuters.com/article/areva-safety-creusot-idUSL5N1GM2XM

  1. So what does this mean for Hinkley Point C ?
    Perhaps UNECE is right to ask the UK Government to stop work on the project in view of EDF’s problems at Flamanville 3 with the EPR reactor.
