Flamanville nuclear safety problem – a knockout blow for UK’s EPR reactor project?

France’s nuclear calamity has UK worried, The Local,  21 Apr 2015 France’s world renowned prowess in the nuclear industry is being seriously undermined by its efforts to build a flagship nuclear reactor which is fast becoming a costly calamity. The future of the Flamanville 3 project appears to hang in the balance after yet another major setback that has London worried.

It was supposed to showcase the expertise of France’s nuclear energy industry to the world and is key to the UK’s own nuclear strategy. But after being beset by hold-ups and snags – the latest and potentially most serious one coming last week, the flagship project to build a new state of the art nuclear reactor, France is getting a reputation for all the wrong reasons and London has been left looking on nervously.

In 2005 the French government proudly gave the green light for construction to begin on the first third-generation nuclear reactor at Flamanville in Normandy on the north coast, a site environmentalists say is threatened by flooding.The third-generation “European Pressurized Reactor” (EPR), built by EDF and Areva, was supposed to be in operation by 2012 and is meant to be one of the safest reactors in the world, and the most energy efficient. It was commissioned as part of France’s nuclear renaissance programme that will see the country’s aging nuclear plants replaced over time.

However Flamanville 3, as it is known, is unlikely to start producing power anytime soon after being hampered by a litany of problems and incidents, including the death of a construction worker in 2011 (see below).

The latest setback came last week when it was revealed that “a very serious fault” had been detected in the steel of the “pressure vessel” – a key component of the reactor, meaning another delay of at least a year was likely. “It is a serious fault, even a very serious fault, because it involves a crucial part of the nuclear reactor,” said Pierre-Franck Chevet, head of France’s nuclear safety agency (ASN).

That “fault” means construction is unlikely to be completed before 2018 and more worryingly, the budget, initially set at €3.3 billion, is now estimated at more than €9 billion and counting.

In short Flamanville has become France’s own “nuclear catastrophe” as it was described in one of the many critical articles in the French press. Tests will need to be carried out on the steel vessel but if after these tests the vessel still does not meet necessary safety standards, it will need to be changed.

“That’s a very difficult operation in terms of costs and time,” said the ASN’s Chevet. The steel vessels weigh around 425 tonnes and stand around 11 metres high so building a new one would take considerable time and come at a huge cost.Changing the vessel would be a major headache given all the construction work that would need to be undone.

Some in the business of nuclear safety have even suggested that if the steel vessel needs replacing then the whole project could be scrapped. That will have authorities in the UK sweating as the same steel has been used to build two vessels destined for the planned EPR nuclear reactors at Hinkley Point in the UK.…….

“This is clearly the knock-out blow for the EPR reactor,” said Yannick Rousselet from Greenpeace. “What foreign client would want to purchase a reactor of this type, if even France itself is not able to complete the construction?

“The bill from the EPR reactor will be so high that it won’t end up showcasing what to do, but exactly the opposite,” said Rousselet. “This is a huge blow to the know-how of the French nuclear industry.”

Greenpeace has called for work at Flamanville to be called off.

“It must be stopped immediately so there is no more wasting of public funds on this industrial nightmare,” said Rousselet, who added that France should be concentrating resources on finding renewable energy solutions……..http://www.thelocal.fr/20150421/flamanville-frances-own-nuclear-nightmare
