Abstract

Abstract

In order to solve the technical problem of precise control for the material irradiation temperature in high heat release rate region of the research reactor, the segmented air-gap coupled electric heating test device for the material irradiation was developed. The irradiation temperature control method of axial segmented air gap coupling electric heating was adopted to enable the irradiation device to have a large temperature regulation ability. The structure of axial segmented yin-yang plane independent partition was adopted in the test device. The irradiation test section loaded with material samples was composed of four independent chambers, each of which was equipped with an independent inert gas regulating circuit, and the two chambers on the first segment were equipped with the electric heating rod auxiliary air gap for the irradiation temperature regulation. This device was used to carry out irradiation test in the research reactor, and the results show that the material irradiation temperature for the test device can be effectively controlled at 335~365℃ in high flux rate region of the research reactor, and the independent temperature control ability of the electric heating rod can reach 30℃. The developed device greatly improves the accuracy of irradiation temperature control, realizes on-line accurate adjustment and control of irradiation temperature, and achieves the purpose of fine temperature control for material irradiation.
