摘要
下管座具有支撑和定位的作用,是CF3燃料组件的重要结构部件。采用有限元计算分析和载荷试验2种方法分别对CF3燃料组件下管座的应力情况和承载能力进行研究,计算结果和试验结果表明,各种工况下CF3燃料组件下管座的应力均满足ASME规范要求,其承载能力达到了CF3燃料组件的设计要求。
Bottom nozzle,used to support and locate,is an important structural component of CF3 fuel assembly.FEM and load test method were adopted to study the mechanical properties of CF3 fuel assembly bottom nozzle.The result shows that the stress on every condition meets the requirement of the ASME code and the carrying capacity meets the design requirement of CF3 fuel assembly.
