四代核电高温部件结构分析设计方法

Structural Analysis and Design Method for Elevated Temperature Components of Gen-Ⅳ

四代核电装备需要在高温、长寿期、载荷复杂等极端条件下服役,产品设计中需要兼顾蠕变、疲劳、蠕变-疲劳交互作用等影响。通过分析英国的R5规程、法国的RCC-MR、美国的ASME-NH,阐述高温部件结构分析设计方法,为核电高温部件设计提供参考。

Gen-IV has to operate under extreme service conditions： elevated temperature, service longevity, complex load and so on. The effect of creep, fatigue, creep-fatigue interaction should be considered in product design. The paper studies British′ s R5, France′ s RCC-MR, USA′ s ASME-NH codes to propose a structural analysis and design method for elevated temperature components, which can be referenced for the design of the elevated temperature components of nuclear power plants.
