French nuclear safety agency stops construction of 'flagship' nuclear reactor

The French nuclear safety agency, ASN, has ordered construction to be suspended on the new nuclear reactor being built in France - the same model that would most likely be built in the UK. (1)

Flamanville's construction in northern France has run into the same kinds of problems plaguing the ongoing construction of the only other European Pressurised Reactor (EPR), Olkiluoto 3, in Finland.

The move by ASN follows the agency's discovery of chronic problems affecting the quality of construction work since building work commenced on Flamanville 3 in December 2007.

ASN's call to halt construction follows a series of letters from the agency to Flamanville's construction manager. In the letters, ASN inspectors highlighted a range of problems including non-conformities in the pinning of the steel framework of the concrete base slab, incorrectly positioned reinforcements, and inadequacy of technical inspections by both the construction companies and Electricité de France (EDF).

Inspectors also uncovered inconsistencies between the blueprint for reinforcement work and the plan for its practical implementation. (2) The incorrect composition of concrete had been used, that may lead to cracks and rapid deterioration. Samples of concrete were also not collected properly, according to ASN. (3)

Cracks have already been observed at part of the base slab beneath the reactor building. The supplier of the steel containment liner reportedly lacks the necessary qualifications. Fabrication of the liner was continuing despite quality failures demonstrating the lack of competence of the supplier. As a result, one-quarter of the welds of the steel liner of the reactor containment building were deficient. (4)

Ben Ayliffe, head of Greenpeace's nuclear campaign, said: "The only two EPRs being built today are construction fiascos. The one in Finland is years behind schedule and billions over budget and only six months into the project in France building work has come screeching to a halt.

"This reactor design is fast becoming a by-word for incompetence, massive delays, spiralling costs and dodgy engineering. We only have a limited time and budget to stave off the most catastrophic effects of climate change and we should stop pouring money down the nuclear black hole."

Olkiluoto has been under construction for three years but has been blighted ever since the concrete was poured. Poor quality concrete, bad welds on the containment liner and low-quality reactor components are among its problems. The schedule for completion has been put back by more than two years and costs have nearly doubled to over 5 billion euros.

Le chantier est donc interrompu pour correction et vérification."
