Areva factory ill-equipped to make nuclear parts - French watchdog
In 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. Creusot Forge is one of the world's few foundries able to make the huge steel components that form the heart of nuclear reactors and is a key part in the French nuclear industry's supply chain.

This is terrible for nuclear power. It may aid LFTRs in France & the EU.

It would be good if this lead to more interest in nonconventional pressure vessels for water reactors in the medium term (alternative reactor deisgns are definitely long term things).

For example prestressed concrete or prestressed cast iron.

New Areva changes name to Orano
Orano said its new name derived from Ouranos, the Greek god who became Uranus in Roman mythology and from whom the planet takes its name. It was later to serve as a point of reference when the term 'uranium' was created.

"Orano symbolizes a new start," said Orano CEO Philippe Knoche. "A new start that has been under preparation for several years now. We have set up a new organisational structure, a new business plan, a new strategic action plan and a new social contract. Our new identity is the natural result of all this."

He added, "Our new name symbolises our conviction: nuclear power has a future, as it is a competitive, low-carbon [source of] energy that creates jobs. Orano has all it needs to play a key role in this. We have big ambitions for Orano, namely for it to become the leader in the production and recycling of nuclear materials, waste management, and dismantling within the next ten years. I have full confidence in our capacity to give nuclear energy its full value."

First criticality achieved at Chinese EPR :

http://www.world-nuclear-news.org/NN-Fi ... 06184.html

Taishan 1 is the first EPR to achieved completion.

Good news for Framatome (Framatome is the "new" name of the reactor branch of Areva, not really new because the company was named Framatome before the creation of Areva, they just took the old name)

And good news for the nuclear sector.
