With the rapid development of information technology, the control systems of Nuclear Power Plants are undergoing a transformation from traditional analog technologies to digitalization and intelligence, a transition that is critical to enhancing the safety and efficiency of NPP. Parallel theory as a new research technique integration theory, practice, and computation, provides a new perspective and tools for this transformation. Based on the parallel theory, this paper discusses its application and fusion in safety-level DCS in NPP. By explaining the parallel theory and analyzing its application requirements in safety-level DCS, the application architecture of safety-level DCS based on the parallel theory is proposed, and the application of the parallel theory in safety-level DCS chassis of NPP is analyzed. It aims to provide theoretical support and practical guidance for the digital transformation and development of safety-level DCS in NPP and other key fields in China and the safe, stable and reliable operation of nuclear power units.

摘要

With the rapid development of information technology, the control systems of Nuclear Power Plants are undergoing a transformation from traditional analog technologies to digitalization and intelligence, a transition that is critical to enhancing the safety and efficiency of NPP. Parallel theory as a new research technique integration theory, practice, and computation, provides a new perspective and tools for this transformation. Based on the parallel theory, this paper discusses its application and fusion in safety-level DCS in NPP. By explaining the parallel theory and analyzing its application requirements in safety-level DCS, the application architecture of safety-level DCS based on the parallel theory is proposed, and the application of the parallel theory in safety-level DCS chassis of NPP is analyzed. It aims to provide theoretical support and practical guidance for the digital transformation and development of safety-level DCS in NPP and other key fields in China and the safe, stable and reliable operation of nuclear power units.
