France Authorises EDF Site Preparation for Second Pair of EPR2 Nuclear Reactors

France has given EDF the go-ahead to start site preparation work for the second pair of new EPR2 reactors proposed under the country’s nuclear new-build programme. The decision, confirmed by the French government, keeps the project on a forward path even though it does not yet permit the main construction of the two units.

The authorisation is specifically for early works on the site designated for the second pair of EPR2 reactors. It is a preparatory step rather than a formal construction start, meaning the utility can begin making the land ready while the broader regulatory and financial process continues.

A preparatory milestone, not a construction start

In nuclear new-build projects, site preparation is distinct from the start of nuclear construction. Early work can include activities such as ground investigations, topographical studies, site clearing, access improvements and the installation of temporary utilities. These steps help de-risk the project and inform later engineering and safety documentation, but they do not by themselves constitute the beginning of reactor construction.

For EDF and its contractors, the government’s permission therefore represents an important practical step. It allows the project team to mobilise on the ground, gather site-specific data and prepare logistics before the main civil works and nuclear island construction can be authorised.

The EPR2 in France’s nuclear revival

The EPR2 is the latest French-designed pressurised water reactor model intended to form the next generation of domestic nuclear capacity. It is a simplified evolution of the EPR design, developed to be built in series and to support France’s long-term objective of maintaining a predominantly low-carbon power mix.

France has placed new reactor construction at the centre of its energy policy. The government and EDF have been advancing a programme of additional EPR2 units, and the second pair now authorised for site preparation forms part of that wider pipeline. Other EPR2 units are already being advanced under the French programme, and this latest decision confirms that the second pair is progressing through the preliminary stages of project development.

How the second pair fits the wider programme

The decision is likely to be read as a signal that France intends to maintain momentum across its reactor programme. Rather than resetting policy, the step focuses on sequencing: early authorisations allow time for site readiness, supply-chain engagement and detailed design work to proceed in parallel with the remaining regulatory approvals.

Several elements will still need to be completed before the main build can begin. These may include environmental assessments, nuclear safety reviews, public consultations and final investment decisions. The government’s site-preparation approval does not remove those requirements, but it does allow EDF to use the current phase to prepare the location and reduce later schedule risk.

• Site readiness: Early site preparation helps establish physical conditions for a future construction site.
• Regulatory sequencing: The approval covers preparatory activities, while full construction remains subject to further permits and safety clearances.
• Programme momentum: The second pair of EPR2s is advancing within France’s broader nuclear new-build roadmap.

What the decision signals for France’s power mix

Beyond the immediate project, the move underlines the role that France’s government continues to assign to nuclear energy in the country’s electricity system. By authorising EDF to begin physical work at an early stage, Paris is reinforcing the message that new reactor construction is being treated as a long-term national infrastructure priority.

For EDF, the site-preparation approval is one of several enabling steps needed to keep the second pair of EPR2 reactors aligned with the government’s broader programme. It does not confirm a final construction schedule or a final investment decision, but it does allow the state-controlled utility to begin turning the planned site into a workable location for one of the next phases of France’s nuclear fleet renewal.

As the programme moves forward, attention is expected to remain on the timing of subsequent regulatory milestones, the state of the EPR2 supply chain and the conditions under which full construction of the second pair would be authorised.
