摘要
三代核电反应堆堆内构件安装过程中多处采用冷装配技术,包括堆内构件堆芯支撑镶块定位销的安装、H/V定位销暗销的安装、DVI导流板衬套的安装等。利用金属材料线性热胀冷缩的特性,模拟整个冷装配的操作过程,掌握冷装配的操作要领,实施冷装配操作,以提高安装的成功率。
The cold assembly technology is applied to manyinstallation processes of reactor core internals of Generation IIInuclear plant, which refers to the installation of dowel pin of reactorvessel internal core support clevis, installation of dowel pin for H/V alignment pin, and the installation of DVI flow deflector. Withthe linear expansion and contraction features of metal materials,it can simulate the whole operation process of cold assembly, soas to grasp the operation essentials of cold assembly, conduct coldassembly processing operation and improve the success rate ofinstallation processing.
