PARIS (Reuters) - France's EDF <EDF.PA> said on Tuesday it was investigating anomalies reported by engineering and construction firm Framatome in its manufacturing of some nuclear reactor components, which did not meet technical standards.
"Framatome has informed EDF of a deviation from technical standards governing the manufacture of nuclear-reactor components," EDF said in a statement.
Components currently in use as well as some that had not yet been installed on any sites were affected, EDF said, adding that it had been investigating to ensure all reactors and components were fit for service.
The anomalies concern weldings on some steam generators.
"EDF informed the French nuclear regulatory authority of its initial investigations," the power group said. "EDF will provide additional information as characterisation work progresses."
