摘　　要：法国RCC-MRx规范提供了高温堆、研究堆和聚变反应堆(ITER)的部件及其附属部件和辐射设备的设计和建造规则。它于2009年整合了RCC-MX2008和RCC-MR2007两部规范,可用于防止过量变形、塑性失稳、弹性及弹塑性失稳、渐增性变形、疲劳、蠕变和快速断裂等破坏形式。主要介绍了RCC-MRx规范的分析方法和评定规则,包括破坏类型、操作工况、安全准则以及分析和设计的规则。还对可忽略蠕变/显著蠕变、可忽略辐射/显著辐射的所有组合下的分析和设计规则进行介绍。In French code RCC-MRx, the construction rules for the components, associated auxiliaries and irradiation devices in high temperature reactors, research reactors and fusion reactors were provided. In 2009, it merged two previous codes - RCC-MX2008 and RCC-MR2007, so that it can be used to analyze the failures of excessive deformation, plastic instability, elastic-plastic instability, progressive deformation, fatigue, creep and fast fracture. In this article, the analysis methods and evaluation criteria in code RCC- MRx were introduced, including damage types, working operations, level of criterion and rules for analysis and design. Further, the rules to take combined conditions into accounts, such as with and without creep, with and without irradiation, were also introduced.
