Building the foundations of tomorrow’s nuclear energy

ALTEN provides comprehensive civil engineering support, from design to execution. We bring technical precision and cross-functional expertise to all stages of nuclear construction: design management, anchor studies, steelwork, and contract management. Our teams are involved in major programs such as EPR2 and Hinkley Point C, guaranteeing quality, safety, and on-time delivery.

Supporting energy projects throughout their lifecycle with a focus on construction and commissioning

Through its specialized entity Anotech, ALTEN provides end-to-end management of energy projects, from construction to commissioning. We combine robust project management and technical expertise to streamline execution, secure supply chains, reduce risks, and guarantee reliable, efficient results that meet customer expectations.

Reliable, qualified systems including nuclear and transportation safety and control

Worldgrid provides comprehensive support throughout the entire lifecycle of critical systems: design, qualification, deployment, and maintenance. With over 40 years of nuclear expertise, Worldgrid ensures that components meet the most stringent standards, reduce risk, and optimize performance, ensuring safety, reliability, and compliance in critical environments.

Ensuring the safety, performance, and longevity of nuclear facilities

ALTEN supports nuclear operators in managing equipment aging and regulatory compliance, enabling the extension of the operational life of power plants. Our Nuclear Services Platform is the leader in France for drafting Continuing Operating Capability Files (DAPE) and coordinating Technical Compliance Reviews (ECOT).

Innovative digital instrumentation and control solutions for nuclear reactors

Worldgrid designs, integrates, and maintains Instrumentation and Control (I&C) systems that comply with the most stringent requirements. As an agnostic integrator, ALTEN offers proprietary or third-party solutions (ADACS-N, other systems) with long-term guarantees of security, compliance, and operational performance.

Transforming the nuclear industry through intelligent systems, IT/OT integration, OT security and operational excellence

Worldgrid drives digital transformation by combining industrial, IT, and OT expertise. We help operators modernize their operations and extend the life of their power plants through secure IT/OT integration and cybersecurity programs aligned with NIST CSF and IEC 62443, ensuring resilience, security, and value from digital transformation.

Driving performance and reliability across complex nuclear design and execution programs

ALTEN acts as the backbone of governance, providing strategic contract management and multidisciplinary expertise on complex programs such as EPR2. We guarantee design maturity, milestone compliance, and project reliability, helping our clients maintain quality, control costs, and secure interfaces.
