The Cour also advised against launching the EPR2 program until the profitability of current projects, particularly Flamanville, is fully assessed.

On January 14, 2025, the Cour des comptes published a critical report expressing significant doubts about the EPR2 program proposed by the French government, particularly highlighting issues with the Flamanville reactor.

The final cost for the Flamanville EPR has reached €23.7 billion, reflecting substantial increases due to inflation and extended construction timelines.

These updated figures align with the findings of the Cour des comptes in their latest report on the EPR program.

This increase in costs is attributed to various factors, including inflation and additional operational expenses, with construction costs alone accounting for €15.6 billion in 2023 euros.

The report urged the French government and EDF to address numerous uncertainties before proceeding with the construction of new nuclear reactors.

The Cour emphasized the need for careful consideration of its recommendations due to the long-term financial, industrial, energy, and environmental stakes involved.

The Cour des comptes criticized EDF for its lack of transparency regarding the profitability and production costs associated with the Flamanville EPR and future EPR2 projects.

However, the financial viability of the EPR2 program remains uncertain, as the funding conditions have not yet been established.

EDF is working to optimize the construction timeline to control expenses, as prolonged projects increase overall costs.

In February 2022, President Macron announced plans to construct six new generation EPR2 nuclear reactors, with an option for eight additional units.

Despite restructuring efforts within EDF, including nationalization and governance changes, the nuclear sector still faces many challenges that could impact the EPR2 project.
