本工作对中国实验快堆二回路钠取样器上非标设备的视镜部分的视镜玻璃进行了设计验证实验。实验验证了3种不同类型的6种规格直径为88mm玻璃。实验结果表明:厚度为8mm的铅玻璃,6mm厚的有机玻璃和5mm厚的钠化玻璃在室温、压力为0.9MPa的工况下,使用性能良好;厚度为6mm的有机玻璃 In this work, the design verification experiment was performed on the mirror glass of the non-standard equipment on the sodium sampler of the second loop of China Experimental Fast Reactor. The experiment validated three different types of six kinds of specifications of 88mm diameter glass. The experimental results show that the lead glass with a thickness of 8mm, the plexiglass with a thickness of 6mm and the soda-lime glass with a thickness of 5mm have good performance at room temperature and pressure of 0.9MPa. The plexiglass with a thickness of 6mm
