Abstract:

Design and construction rules for mechanical components of nuclear installations (RCC-MR 2007) code are prescribed for design and manufacture of components or parts that form plasma chamber first confinement barrier and some system related components in ITER Project. On the base of contents of RCC-MR 2007, the differences of general requirements, materials, design rules and analysis rules for component behavior among Class 1 components, Class 2 components and Class 3 components are analyzed and compared. The differences of design requirements for shells, piping, box structures, heat exchanger elements, valves, and bellows among three Classes are also analyzed and compared.

Key words: RCC-MR 2007, Components, Design requirements, Analysis, ITER

摘要：

核装置机械部件设计和建造规则(RCC-MR 2007)是ITER装置中构成等离子体腔室第一道密封屏障的设备或部件设计和制造的依据。本文在研究RCC-MR 2007主要内容的基础上，分析了RCC-MR 2007中1、2、3级机械设备设计相关的通用要求、材料要求、设计通则、设备性能分析要求之间的区别，同时对1、2、3级壳体、管道、箱式结构、热交换器、阀门和波纹管设计要求之间的差异进行了分析。
