一、引言压水堆中常采用银-铟-镉合金及硼不锈钢作控制棒及可燃毒物材料;冷变形的188不锈钢作控制棒包壳材料;固溶的18-8不锈钢作导向管材料。由于控制棒减速的需要,导向管上加工了若干段缩颈,并在缩颈段要进行一定温度的退火处理。本工作的目的是研究控制棒组件材料在模拟压水堆一回路条件下的耐腐蚀性。
First, the introduction PWR often used silver - indium - cadmium alloy and boron stainless steel as a control rod and combustible poison material; cold deformed 188 stainless steel shell material for the control rod; 18-8 stainless steel solution for the guide tube material. Due to the need of slowing down of the control rod, a number of segments of neck are machined on the guide tube, and a certain temperature is annealed in the neck segment. The purpose of this work is to study the corrosion resistance of the control rod assembly material under the condition of a primary circuit of the PWR.
