To address the demands of multi-level business activities of nuclear reactors, leveraging advancements in digital technology, a digital reactor platform architecture characterized by a unified platform and two fundamental cores has been developed. Furthermore, the design of the technical architecture has been implemented through comprehensive integration and application, numerical computation cores, and big data frameworks, thereby empowering the full life-cycle management of nuclear reactors. The key technologies, problems and challenges in the application of digital reactor are analyzed and studied, and the subsequent development trend is analyzed and prospected.
