Jiangsu Nuclear Power Corporation monitors its nuclear power plant with AVEVA PI System
Jiangsu Nuclear Power Corporation operates the Tianwan plant, located 500 km north of Shanghai, which by 2027 will become the largest nuclear power plant in China and the world. The operator needed to capture enough data points to produce meaningful analyses, integrate multiple platforms on-site and nationwide, and support a site under constant construction. Deploying AVEVA PI System, complemented by PI ProcessBook, made it possible to extract all production process data in real time and present it as easy-to-read charts for analysis. Custom dashboards are tailored to the different staff roles, from engineers to supervisors. When data deviates from expected results, teams can quickly diagnose anomalies. The plant also benefits from comparisons with similar facilities in China, paving the way for unprecedented experience sharing in the Chinese nuclear industry.

FAQ
How does AVEVA PI System manage data for the world's largest nuclear power plant?
The Tianwan plant operated by Jiangsu Nuclear Power Corporation will become the world's largest nuclear power plant by 2027. AVEVA PI System captures millions of data points from equipment in real time and structures them for meaningful analysis. The platform adapts to a site under continuous construction, progressively integrating each new unit. It is an emblematic use case for very large-scale data management in the nuclear sector, where the quality and availability of information are critical to safety.
How does AVEVA PI ProcessBook customize dashboards for each role?
AVEVA PI ProcessBook allows Jiangsu Nuclear Power to create dashboards tailored to each user profile: process engineers, control room operators, supervisors and management. Each dashboard presents the relevant data at the right level of detail, speeding up decision-making and collaboration between teams. This role-based customization is essential in an environment as complex as a nuclear power plant, where each stakeholder has specific information needs while sharing a common repository through PI System.
Why is cross-plant benchmarking an asset for the Chinese nuclear industry?
AVEVA PI System gives Jiangsu Nuclear Power access to the experience of other Chinese power plants through comparisons of similar equipment. This unprecedented sharing of experience speeds up the spread of best practices, the identification of failure signatures and the continuous improvement of performance. For a fast-growing sector like Chinese nuclear power, this ability to pool lessons learned becomes a major competitive advantage, supporting both the safety and the economic efficiency of the entire fleet.
How does AVEVA support a site that is constantly under construction?
The Tianwan plant is continually growing, with new units under construction. AVEVA PI System is designed to evolve without disruption: new sensors, equipment and units can be added gradually to the platform, inheriting existing models and dashboards. This built-in scalability avoids architectural breaks and preserves operational continuity. It is a decisive advantage for major nuclear projects that span several decades between the first unit and full completion.
How does AVEVA PI System speed up anomaly diagnosis at a nuclear power plant?
When operational data deviates from expected results, Jiangsu Nuclear Power's engineers can quickly analyze and diagnose problems thanks to AVEVA PI System. The platform correlates process parameters, recent history and cross-plant benchmarks to quickly identify the root cause. Faster diagnosis is critical in a nuclear environment, where every minute of responsiveness contributes to safety, production availability and the confidence of regulatory authorities.
