In March 2025, CORYS completed the renovation of the full-scope training simulator for the Taishan EPR plant in China, a three-year project aimed at faithfully reflecting real operational data.
This update enhances the accuracy of simulations, particularly through adjustments based on unit recordings, providing increased fidelity to actual operations.
The project required a comprehensive overhaul of the 300 original models, which were based on engineering data. The work included modernizing the I&C system, updating and adding numerous systems, and replacing computer equipment.
The secondary control panel was renovated and connected to the simulator, requiring the integration of over 6,000 input/output connections on-site. Despite a three-month delay in the delivery of certain input data, the project was successfully completed within the contractual timeline.
The ALICES models and the DRAC thermohydraulic code demonstrated high representativeness by accurately reproducing curves from the real installation during full-scale nuclear simulator tests. This validation confirmed the strong accuracy of the models and the simulator’s robustness in handling transients, which were studied and compared with unit data over several weeks.
The testing phases were particularly intense, with workdays extending up to 16 hours (2×8-hour shifts), both during the factory acceptance test and in Taishan. The team now provides a two-year warranty, continuing its long-term commitment to the project.
