After France raised the cost of its Cigéo nuclear waste storage project to €33.3 billion, an increase of more than €8 billion, authorities are preparing to open a public inquiry into the plan – which has long faced opposition from anti-nuclear groups.
The new estimated cost replaces a €25 billion figure set in 2016. It reflects updated costs and sits within a €26.1 to €37.5bn range set in May 2025 by the National Agency for Radioactive Waste Management, which is leading the project.
