Nuclear industry differs from most other industries in the characters of large scaling, long period and multiple collaborating institutions . Traditionally, the material codes are compiled respectively by collaborating institutions of nuclear power plant projects, so the whole code system lacks unified management and planning, causing many defects such as the incompleteness in information coverage, the inconformity in classification and description of materials and the confusion in commodity codes. So, it is of great significance in setting up a standard nuclear power material code system to effectively enhance the efficiency of design and management, and to ensure the schedules of the projects.
This article introduces in detail the entire process of the setting up and application of the material code system of State Nuclear Power Technology Company (SNPTC) by Shanghai Nuclear Engineering Research & Design Institute (SNERDI) for the CAP1400 nuclear power plant project. The application of the material code system in the CAP1400 project remarkably simplifies the work of design, material take-off and purchase, improving the project’s quality.
