Assystem, an international engineering and digital services group, was contracted by the United Kingdom Atomic Energy Authority (UKAEA) to develop physics-based digital twins for their operational fusion powerplants. The challenge was that fusion powerplants required complex digital simulation models during the design assessment phase. The inspection and maintenance intervals and total life of these powerplants were defined based on the expected loading on the as-designed model, which often differed from the actual loads the plant was subjected to. This discrepancy provided a scope for programs aimed at improving the plant’s lifetime value or quantifying the effects of higher-than-expected usage. Assystem wanted to leverage the expensive design models to create a digital twin by inputting the sensor data that was livestreamed from the plant. This would help engineers understand the plant’s structural integrity and further optimize inspection and maintenance schedules.

The solution involved the use of the hosted version of Altair SmartWorks IoT, which formed the backbone and analytic front end of the solution. It allowed automation through serverless backend functions, data storage, edge connectivity to the operational systems, and advanced dashboarding capabilities that provided users with immediate insight. The pilot phase used synthetic data to simulate the real-time data stream from operating plants into the IoT platform. Defined Python scripts triggered related physics models, which then processed the data and returned the results back to the IoT platform. A configured front end provided visual analytics highlighting event repercussions for better decision-making. Finite element analysis (FEA) models from multiple vendors, a commercial-grade fatigue analysis solver, and real-time weather data from OpenWeather were all connected to the IoT platform. The Simulation Process Data Management (SPDM) system at UKAEA was linked to store the data models. Email and SMS were also integrated to alert the operators to exceptional events.

The implementation of SmartWorks IoT helped Assystem create a seamless data flow between the plant and the physics-based models, resulting in a true digital twin. The incorporation of virtual sensors allowed engineers to make better decisions regarding support on fatigue damage and also helped calculate the remaining useful life (RUL) of the powerplants. This insight into the impact of real loading conditions improved efficiency and maintenance schedules, further extending the plant’s useful life. Additionally, using the original design models in the digital twin solution resulted in a higher return on Assystem’s development investments.
