Abstract.
The article is devoted to the urgent task of creating digital twins of power units of NPPs with a VVER-1000 reactor based on flexible modeling complexes. Digital twins can significantly improve operational monitoring, diagnostics, control, and forecasting of the state of process systems, which is especially important in increasing requirements for nuclear energy safety and efficiency. The paper analyzes the current state of digital modeling technologies, emphasizes their increasing role in nuclear energy, and discusses existing solutions’ main advantages and disadvantages. The primary attention is paid to the concept of a flexible modeling complex as a key component in developing digital twins. It is emphasized that the flexibility of the architecture of this complex provides the ability to adapt to various operating modes of power units and changes in their performance characteristics.
Keywords:
