French Nuclear Watchdog Says EDF Has Problems With Flamanville EPR Liner

From Bloomberg:

Electricite de France SA, Europe’s biggest power producer, experienced renewed problems with welding quality at the EPR nuclear reactor being built in Normandy, according France’s nuclear safety agency.

Faults in welds of the containment liner of the Flamanville EPR, the utility’s first in France, were found during an inspection in July, the Autorite de Surete Nucleaire said in an Aug. 27 report on its website. EDF officials weren’t immediately available for a comment.

“Welding difficulties caused by the ergonomics of the welder’s post” were the cause of similar problems at the building site in 2008 and 2009 and treatment by EDF “was not performed correctly,” according to the report. The agency also said EDF was slow in detecting “inferior weld quality.”

EDF’s EPR, which was designed by Areva SA, is considered key to the utility’s ability to export nuclear technology to other countries. Earlier this month, EDF was asked for modifications of the control platform on the reactor, which is delayed and will cost more than expected.
