Atos wins EDF contract to build nuclear OIMS platform for EPR exports

Atos and EDF have signed a partnership of up to 15 years to develop a digital operations platform for EDF's international EPR nuclear projects.

Atos has been selected by French utility EDF to design, develop and operate an Operations Information Management System (OIMS) for EDF's EPR reactor export projects. The partnership, which can run for up to 15 years, is aimed at providing international clients of EDF's EPR programme with a standardised, turnkey digital platform covering operations and maintenance from the moment a plant is handed over.

The OIMS is described by both parties as the digital backbone of a nuclear power plant, integrating data management, business processes, IT/OT convergence, and cybersecurity into a single, replicable architecture. Atos says the platform is designed to be scalable across multiple national programmes, with the stated ambition of setting a new benchmark for nuclear operations management internationally.

Xavier Ursat, EDF's group senior executive vice president for strategy, technologies, innovation and development, said the integrated approach "ensures seamless digital continuity of data throughout the entire lifecycle of the plant, from design and construction through to operation."

Deal substance and scope

Neither party disclosed the contract value. The release does not name specific export markets or named-customer programmes already under contract, beyond the general reference to "new nuclear programs outside of France." Atos will draw on its own global partner network to support local content requirements in host countries, which is a common condition in nuclear procurement.

The platform's cited performance goals include reduced downtime, improved maintenance-cycle optimisation, better equipment reliability through data traceability, and faster change management for plant operators. Cybersecurity and operational resilience are stated as foundational design principles, reflecting the stringent availability and integrity standards that nuclear regulators impose on digital control environments.

Franck Chartier, executive vice president and head of Atos France, framed the partnership as a response to "the global revival of nuclear energy," noting that performance gains will depend on the ability to integrate data, processes and technologies at scale across complex, long-duration programmes.

Market and regulatory context

The agreement sits at the intersection of two converging trends: a broad resurgence in nuclear new-build investment and an accelerating push to digitise critical infrastructure. Several governments, including those of the UK, Poland, the Czech Republic and a number of markets in Asia and the Middle East, are either advancing or actively tendering EPR or equivalent large-reactor projects. EDF's EPR export pipeline is a strategic priority for the French government, which views nuclear technology as a pillar of both energy sovereignty and industrial export policy.

For Atos, the contract is significant in the context of the group's ongoing restructuring. Atos Group has been working through a financial and operational reorganisation, and a long-duration contract with a sovereign-backed counterparty of EDF's scale provides a measure of revenue visibility that will be of interest to creditors and investors alike.

On the regulatory side, nuclear digital infrastructure sits under particularly demanding frameworks. In Europe, the EU's NIS2 Directive explicitly covers operators of essential services in the energy sector, mandating incident reporting, supply-chain security assessments, and resilience testing. National nuclear regulators add further layers: in France, the Autorité de Sûreté Nucléaire sets requirements for digital I&C systems, and export programmes must satisfy equivalent bodies in host countries. The OIMS will need to demonstrate compliance with each jurisdiction's regime, which partly explains the emphasis on traceability, data integrity, and interoperability in the platform design.

The broader enterprise software market for critical-infrastructure operations management is contested by a small number of specialised vendors alongside the large industrial software groups. The combination of EDF's operational pedigree and Atos' cybersecurity and integration capability is positioned as a differentiator, though independent validation of platform performance will matter as export programmes progress to procurement.
