The Bugey Nuclear Power Plant is located in Bugey in the Saint-Vulbas commune (Ain), about 75 km from the Swiss border.

The site houses 4 currently operating units, all being pressurized water reactors.

In the last few years, the plant was modernized to updated earthquake resistance standards.

Again on 30 July 2003, water was directly discharged into the Rhône for 9 hours.

Bugey 5 was offline from August 2015 to July 2017 due to an air leak in the inner liner of its containment.
