Abstract

The nuclear power engineering information model is a specific type of information model that matches the business model of nuclear power engineering construction. It is a set of related information about the structure, system, and components of nuclear power plants, including a large amount of design data, relationships, and rules, used to integrate, express, and describe the processes and data of various stages of the entire life cycle of nuclear power plants. The information model of nuclear power engineering supports requirement management, configuration management, and physical configuration management of power plants throughout the entire cycle of nuclear power engineering^[1]. Among them, configuration management plays a crucial role in the construction of nuclear power projects, connecting demand upwards and regulating the actual physical configuration of power plants downwards. The configuration item structure is generally carried out according to the SSC hierarchical method. Due to certain requirements that cannot be connected to SSC items, dedicated nodes must be added to supplement the configuration item structure. With a large number of configuration items in nuclear power engineering and complex association and constraints, its accurate expression requires strict and multi-dimensional association engineering data structure specifications, and the matching software database must fully adapt to these data structures and association rules in order to meet the management requirements of software on data permission, status and association. This paper mainly discusses the logical structure composition of nuclear power engineering configuration items, describes the data model from the aspects of engineering object type and attribute structure, equipment model, multi-layer function model, etc., and applies this model to construct information model. It will help to meet the data requirements of the nuclear power engineering project for information consistency with configuration items, multi-dimensional deconstruction and separation, and data status control and tracking, improve the efficiency and quality of information flow of nuclear engineering projects, shorten the construction period and reduce the construction cost.
