摘　　要：用于10MW高温气冷实验堆的高可靠性铠装热电偶测温装置,分别测量一回路介质温度、压力容器表面温度以及堆内构件的温度,属于安全(1E)级和安全有关(SR)级仪表。经过两年多时间的反应堆功率运行,证明其选材正确,结构合理,完全满足10MW高温气冷实验堆的运行要求。This paper presents a high-reliability thermocouple tempera ture-measuring unit for use with the 10-MW high-temperature gas-cooled reactor（HTR-10）. The thermocouple temperature-measuring units with class IE and SR are used to measure the helium temperature and the surface temperature of the vessels of both reactor and evaporator as well as the temperature of components in the reactor vessel. The power operating experience of the HTR-10 for more then two years shows that the selection of materials is correct and their structure is reasonable. They can meet the requirements of the HTR-10.
