France's Nuclear Reactor Has Been Delayed Again

Welding problems will require a further six-month delay for France's next-generation nuclear reactor at Flamanville, the latest setback for the flagship technology the country hopes to sell worldwide, state-owned electricity group EDF said Friday. Barron's reports: The delay will also add 500 million euros to a project whose total cost is now estimated at around 13 billion euros ($13.8 billion), blowing past the initial projection of 3.3 billion euros when construction began in 2007. It comes as EDF is already struggling to restart dozens of nuclear reactors taken down for maintenance or safety work that has proved more challenging than originally thought.

EDF also said Friday that one of the two conventional reactors at Flamanville would not be brought back online until February 19 instead of next week as planned, while one at Penly in northwest Farnce would be restarted on March 20 instead of in January. EDF said the latest problems at Flamanville, on the English Channel in Normandy, emerged last summer when engineers discovered that welds in cooling pipes for the new pressurized water reactor, called EPR, were not tolerating extreme heat as expected. As a result, the new reactor will be start generating power only in mid-2024.
