Application of Detail Design Data of Nuclear Power Plant in Project Construction and Operation Under the Background of Digitization

Building Information Modeling theory has been more and more welcome all over the world, and has been introduced into nuclear power industry. The so-called ‘smart power station’ being established by many nuclear power enterprises is the embodiment of BIM. With the deepening of digital design and application, the design data has become more and more detailed and accurate, to support all design work such as data exchange between systems and software, automatic drafting, automatic material and working counting, and so on. In addition to design, how should the procurement, construction, installation and power station operation engineers use these data to improve their work efficiency and accuracy is a research topic, which has been highly followed by engineering companies at present. At the same time, the design data is more for design itself. Whether its expression form, depth and breadth can meet the requirements of downstream engineers and how to improve efficiently when they are not satisfied is an important issue that all project participants should pay attention to. This paper gives a sketch of 3D design data, with pipework as an example, to elaborate how to use design data to help other engineers to break down old-style of working mode, and gives some thinking about optimizing design data efficiently to fulfill the requirement of other project participants.
