Abstract: As the digital design paradigm of nuclear power evolves, the complexity of collaborative design tasks across departments, disciplines, and domains escalates. Aiming at the common problems existing in the simulation verification process of digital nuclear power design, this paper studies the enterprise-level simulation process and data management (SPDM) technology, and develops a simulation verification platform for digital nuclear power design. The system achieves software integration and data control in various domains, including design, modeling, simulation, and testing software. This development has laid the foundation for the digital transformation of design verification in nuclear power scenarios.
