摘要: 为解决高温气冷堆示范工程（HTR-PM）蒸汽发生器绝热材料装配问题，保证绝热材料达到设计要求的填充密度及压力，针对于蒸汽发生器不同位置进行装配工艺试验研究，通过试验测量压缩与回弹关系，得到不同压力下的保温材料填充密度。试验结果表明，热氦气侧采用毯状绝热材料，冷氦气侧采用锥形块及絮状绝热材料，可以满足设计要求的密度及压力。因此，通过本研究成功解决了蒸汽发生器绝热材料装配问题，为后续高温气冷堆项目建设提供了技术保障。Abstract: In order to solve the assembly problem of insulation materials for steam generator of high temperature gas cooled reactor demonstration project (HTR-PM) and ensure that the insulation materials meets meet the design requirements of filling density and pressure, the assembly process test was carried out at different positions of the steam generator. The filling density of insulation material under different pressure was obtained by measuring the relationship between compression and rebound through test. The results show that blanket insulation material is used on the hot helium side and conical block and flocculent insulation material on the cold helium side, which can meet the density and pressure requirements of the design. Therefore, the assembly problem of steam generator insulation materials has been successfully solved through this research, which provides technical guarantee for the subsequent construction of high temperature gas-cooled reactor projects.
