China Deploys Fully Domestic Industrial Internet Platform for Nuclear Sector

China National Nuclear Corporation's instrumentation and control subsidiary, CNNC Control, has deployed a fully domestic industrial internet platform designed specifically for nuclear facilities, according to a report in People's Daily. The platform achieves complete domestic substitution across underlying chips, operating systems, databases, and industrial software applications. Engineered to interoperate with domestic distributed control systems (DCS) at millisecond latency, the architecture aims to resolve persistent data silos across nuclear power, fuel, and chemical operations while ensuring critical infrastructure remains insulated from foreign software dependencies.

Nuclear operations represent one of the most security-sensitive industrial environments, where software vulnerabilities or external dependency present strategic risks. By unifying real-time DCS telemetry with higher-level industrial internet applications on an entirely homegrown technology stack, the initiative secures operational control sovereignty and establishes digital foundations for broader nuclear fleet management.

A specialized subsidiary of China National Nuclear Corporation (CNNC) has deployed an entirely domestically developed industrial internet platform tailored for high-security nuclear environments, according to an account published by People's Daily by a chief expert at CNNC Control Systems Engineering Co. The platform achieves 100 percent domestic supply chain coverage across its foundational technology stack, including underlying microchips, operating systems, databases, and upper-level industrial applications. The development aims to fill long-standing gaps in the digital infrastructure governing nuclear plant control zones, eliminating external technology dependencies across critical operational layers. According to the development team, nuclear facilities previously faced significant integration bottlenecks. While China achieved domestic autonomy in distributed control systems (DCS)—the operational 'brain' of nuclear installations—over the past decade, disparate standards across nuclear power generation, fuel fabrication, and chemical facilities created isolated data silos. Commercial off-the-shelf industrial software and standard cloud-based industrial internet solutions proved ill-suited for the rigorous real-time determinism and strict safety isolation mandated by nuclear standards. To bridge the gap between high-level data analytics and physical plant operations without compromising safety, CNNC Control developed a proprietary high-speed communication protocol. This protocol enables millisecond-level data exchange between the industrial internet layer and the DCS while preserving the control system's independent, fail-safe operational boundary. The platform also integrates an integrated development suite containing over 200 industrial mechanism models, which the team claims shortens application development cycles from several months to a few days. Prior to entering wider deployment, the platform served as the technical foundation for China's first national-level intelligent manufacturing standard application pilot in the nuclear sector. Project engineers reported measurable improvements in design efficiency, testing execution, and production throughput, alongside full lifecycle data traceability and automated regulatory compliance verification. Following on-site operational evaluations, the system is now transitioning from initial pilot deployments toward broader adoption across China's nuclear industry.
