The space nuclear reactor power source (SNRPS) offers advantages such as independence from solar energy, a wide power range, and excellent environmental adaptability, making it an ideal power source for constructing the lunar base. However, unlike ground-based nuclear power plants, SNRPS cannot rely on the distributed control system and operators for state monitoring and precise control, resulting in innovative yet high-risk challenges. Establishing a Digital Twin-based Operational Control Platform (DT-OCP) on the ground, combined with the communication system, is crucial for enabling real-time monitoring, fault detection, and control support for SNRPS. This paper proposes a conceptual design of DT-OCP for SNRPS. Key technologies are discussed, and recommendations for technological breakthroughs and engineering development are provided.

摘要

The space nuclear reactor power source (SNRPS) offers advantages such as independence from solar energy, a wide power range, and excellent environmental adaptability, making it an ideal power source for constructing the lunar base. However, unlike ground-based nuclear power plants, SNRPS cannot rely on the distributed control system and operators for state monitoring and precise control, resulting in innovative yet high-risk challenges. Establishing a Digital Twin-based Operational Control Platform (DT-OCP) on the ground, combined with the communication system, is crucial for enabling real-time monitoring, fault detection, and control support for SNRPS. This paper proposes a conceptual design of DT-OCP for SNRPS. Key technologies are discussed, and recommendations for technological breakthroughs and engineering development are provided.
