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.
