到1990年底,已经建成高温钠腐蚀回路,可用来模拟快堆工况下包壳材料和结构材料耐腐蚀性能试验。回路参数如下:温度: 600℃;流速: 2—12m/s;氧含量:<10pp m。回路由主回路、冷阱净化旁路、氩气保护系统和测量控制系统组成。主回路系统由电磁泵、主加热器、膨胀罐和二个试验段组成。试验段中放有样品盒,试验样品装在样
By the end of 1990, a high-temperature sodium corrosion circuit has been built and can be used to simulate the corrosion resistance of cladding and structural materials under fast reactor conditions. Loop parameters are as follows: Temperature: 600 ° C; Flow rate: 2-12 m / s; Oxygen content: <10pp m. Loop from the main circuit, cold trap purification bypass, argon protection system and measurement control system. The main loop system consists of electromagnetic pump, main heater, expansion tank and two test sections. Test section put a sample box, the test sample loaded in the sample
