Electricite de France SA will curtail production at one nuclear reactor this weekend as a heat wave restricts the amount of water that can be discharged into the Rhone River.

The utility had warned of possible curbs on output earlier this week as warm weather swept southern France, pushing up temperatures on the Rhone. EDF uses water to cool its reactors before releasing it into the river, and overheating the waterway can threaten fish and other wildlife.
