France's ASNR Sees No Barrier to EDF Reactors Running Beyond 60 Years

Why the timing matters for supply

The deadline is closely watched by EDF because the 56 reactors commissioned in the 1980s came online over roughly 15 years, AFP said. Without extensions, they could close permanently within a relatively short window. Abadie framed the exercise as a question of system safety, so that public authorities are never forced to choose between safety and security of supply.

For anyone planning electricity supply for data centers in France and neighbouring markets, the point is firm capacity. Nuclear output that stays available into the 2040s and beyond is capacity that does not have to be replaced on a tight schedule. AFP did not link the opinion to data-center demand, and Voltgrid draws that connection as context only. Voltgrid News also covered The Nuclear Company's plan for a Kentucky reactor campus.

What the regulator examined

Abadie said ASNR looked for show-stoppers, meaning ageing of safety-critical items that are hard or impossible to replace. He named the reactor vessel, the vessel pit and certain elbows of the primary circuit. Two further pressures are reactors varying their output more often as intermittent renewables grow, and climate change. He called climate the topic with the most long-term uncertainty, because scientific knowledge of its effects keeps changing, but also one where EDF has remedies, such as equipment changes and stronger water retention upstream of plants.

Reactors in France are authorised without a time limit. EDF must carry out a thorough review every ten years, and ASNR can set conditions for continued operation. The 60-year marks arrive around 2030 to 2040, per Abadie, and the work to 2035 includes identifying safety improvements. A generic review for all reactors will be followed by site-by-site reviews, because each unit has its own conditions.

Montel News reported in September, citing two unnamed sources, that the regulator was set to find no major technical obstacles for 32 of EDF's 900 MW reactors. Bloomberg ran the news on Oct. 22 under a headline saying EDF has ways to prolong reactor life beyond 60 years.

What is not confirmed yet

The final opinion has not been issued, and consultation runs to Dec. 2. EDF still has to demonstrate that its remedies work, and Abadie said vigilance must continue because the fleet is highly standardised, so a defect found in one reactor could matter for many. No reactor has been approved for operation past 60 years, and no extension is granted by this draft.
