摘要：屈曲是快堆关键部件的重要失效模式,涉及地震载荷下的反应堆主容器、轴压载荷下的泵和换热器支撑筒等部件。为保证反应堆安全可靠地运行,相关部件的屈曲设计至关重要。针对快堆瞬时屈曲和蠕变屈曲失效模式,介绍了ASME规范和RCC-MRx标准中的屈曲设计方法,分析了不同设计方法的差异。最后以轴压载荷下的圆柱壳为例,开展了基于ASME规范和RCC-MRx标准中屈曲设计方法的应用案例研究。
Buckling is a main failure mode of some critical components in fast reactor,involving main vessel of the reactor under seismic load,support cylinders of pump and heat exchanger under axial load,etc.In order to ensure safe and reliable operation of the reactor, the buckling design of relevant components is of vital importance.In view of the failure modes such as the instantaneous buckling and creep buckling,the buckling design methods in ASME and RCC-MRx codes were introduced and the differences in these design methods were analyzed.Finally,an application case based on buckling design methods in ASME and RCC- MRx was studied by taking an axial compressive cylindrical shell as an example.
