Development of support tool for control design of nuclear power plant using hierarchical control chart (HCC)

Control design of complex systems, such as nuclear power plants (NPP), is multidimensional problem that requires concurrent engineering environment. This paper presents the idea of integrating process and control models and associated knowledge using hierarchical control chart (HCC), which supports control activities throughout the analysis, design, and operation phases. Automated solution for implementing HCC is developed and presented using a selected case study of steam generator control design of nuclear power plant. Integrated knowledge architecture is presented to support different views during the control design stage: process design, control analysis, control design, control programming, operation, and troubleshooting. The proposed solution will provide better ways to structure and share control knowledge, which will reduce overall risks in the engineering process.
