Areva said the problem was linked to the "sporadic dysfunction of the control system" in zirconium tubes, which are used to encase fuel rods at nuclear plants.
The company said the issue occurred at its Paimboeuf production site in Western France.
Areva said it had informed its customers that the tubes should not be used.
The IFSN said that the Leibstadt plant had already been shut down for regularly scheduled maintainance when the problem emerged, and that the site would remain closed through the end of the year while the issue was resolved.
The tubes are being replaced "for safety reasons", the agency said. ■
