French utility EDF has detected quality deviations on certain welds at its new Flamanville-3 reactor and has informed the nuclear safety regulator ASN, it said Tuesday. Possible adjustments to the start-up timetable and costs can only be made after further checks and the licensing process by the ASN, it added. The new EPR reactor is expected to reach full power in Q4 2019 with fuel loading and first hot tests scheduled at the end of this year. The quality deviations concern the welding of pipes on the main secondary system and are in addition to a deviation with respect to the correct application of “high-quality” requirements of the main secondary system that EDF flagged on February 22 to the ASN, it said. EDF has decided to carry out additional controls on the 150 welds in question and has ordered a full report into the causes and nature of the deviations. The additional controls and report will be completed by the end of May, it added. EDF pegs construction costs for the Flamanville EPR at Eur10.5 billion ($12.9 billion).

Problems with weldings at a nuclear reactor under construction in Flamanville are worse than first expected and may impact the cost and start-up of the long-delayed project, French state-owned utility EDF said on Tuesday. When EDF first reported weldings problems on Feb. 22, it initially said there would be no impact on safety, costs or the reactor start-up schedule. However, France’s ASN nuclear regulator warned on Feb. 28 that the substandard welding could well have an impact on Flamanville’s startup. Even before the welding problems emerged, ASN had warned several times the reactor’s construction schedule was tight. “Following the current checks and the licensing process by the ASN, EDF will be able to specify whether the project requires an adjustment to its timetable and its costs,” EDF said in a statement about the site in northern France. EDF shares fell as much as 2.2 percent in early trading, then recovered to stand one percent lower.

After discovering fresh “quality variations” in the welding at its troubled Flamanville 3 nuclear project in Normandy, Electricité de France (EDF) has reported the issue as “significant” to the Nuclear Safety Authority, and warns it could lead to yet more delays. Shares in the company fell 1.6% on the start of trading on the Paris stock exchange. The UK’s plans to build two EPRs at Hinkley Point depend on the success of Flamanville: government loan guarantees require the Normandy site to be up and running by 2020.

Quality deviations have been detected on certain welds of the main secondary system in the EPR reactor under construction at Flamanville, northern France, EDF announced today. The utility has informed the French regulator of the discovery, but has yet to determine whether the unit’s start-up, expected at the end of this year, will be delayed.
