Paris, May 28, 2026. EDF and Mistral announce the signing of a partnership agreement aimed at collaborating in the field of artificial intelligence to enhance the Group’s efficiency and performance in its engineering, maintenance, and construction activities for future EPR2 reactors.

Concluded for a duration of five years, this partnership will enable both companies to work on the development and deployment of artificial intelligence tools tailored to EDF Group’s safety, industrial performance, and regulatory requirements. The data will remain the property of EDF and will be hosted on trusted infrastructures (sovereign cloud or EDF data centers).

The results of this collaboration are intended to provide concrete support to field teams by improving responsiveness, efficiency, and operational performance.

The partnership notably plans to train conversational agents capable of querying the “technical memory” accumulated across the entire French nuclear fleet and EDF construction sites, while complying with the safety, security, and sovereignty requirements inherent to these operations.

This support for teams will facilitate industrial maintenance operations as well as access to knowledge for nuclear engineering and will optimize activities on construction sites under the EPR2 program.

The AI tools envisioned as part of this partnership will not concern nuclear plant control systems.

Arthur Mensch, CEO and co-founder of Mistral, stated: 

“This partnership with EDF illustrates the importance of independent AI in addressing critical nuclear challenges. We are deploying our cutting-edge solutions and expertise within their environment and adapting them to their industrial context. This is to enable nuclear professionals to perform more effectively in their daily work thanks to AI, while fully complying with the strictest safety and security requirements.”

Bernard Fontana, Chairman and CEO of EDF Group, added:

 “This partnership with Mistral AI strengthens our digital sovereignty by developing AI designed as closely as possible to our core activities, leveraging our data assets and hosted on trusted infrastructures. The objective is clear: to use AI to improve operational efficiency while ensuring safety, security, and quality.”
