锆锡合金的辐照生长及在燃料组件结构设计中的考虑

Irradiation-Induced Growth of Zircaloy and Its Effect on the Mechanical Design of Fuel Assemblies

锆锡合金由于中子辐照而引起生长。生长量是锆锡合金材料的织构、辐照温度、快积分通量和冷作量的函数。在燃料组件结构设计中应给予足够的重视。

Zircaloy growth could be induced due to irradiation.The ammount of growth is described as a function of texture,irradiation temperature,fast neutron fluence and the reduction of cold work, and it should be given great attention in the mechanical design of fuel assemblies.
