SPIC unveils China's fully autonomous nuclear simulator in Beijing

State Power Investment Corp (SPIC) unveiled China's fully autonomous full-scope nuclear energy simulator in Beijing on Monday, marking a critical technological breakthrough that ends foreign reliance in advanced nuclear operator training systems.

The full-scope simulator serves as a crucial piece of equipment for nuclear power plant operations, specifically designed for the rigorous training and licensing examinations of plant operators.

Developed by the SPIC Central Research Institute in collaboration with key subsidiaries, the system integrates three core proprietary technologies: the "Hejing" simulation platform, the "Herui" instrument and control simulation software, and the "COSINE" calculation software.

The simulator successfully passed its final acceptance review on Sept 18 following 23 months of comprehensive testing. This included 720 hours of trial operations and 126 training scenarios conducted by the first batch of operators of the Guohe One advanced nuclear reactor.

According to SPIC, the new system features ultra-real-time, high-precision calculation capabilities. The system can accurately replicate all plant conditions—from normal operations to severe accidents with 100-millisecond precision.

The breakthrough significantly strengthens the technical foundation of domestic operator training, ensuring higher safety standards and supporting the high-quality expansion of China's nuclear power industry, the company said.
