Thermal Performance Test of the Hot Gas Duct of 10MW High Temperature Reactor Test Module

摘要

The thermal performance test of the horizontal coaxial double tube hot gas duct (HGD) with an internal thermal insulation for the 10MW High Temperature Reactor Test Module (HTR-10) was conducted on a Helium Test Loop (HETL). The present paper deals with the technical feature of the HETL, the test section and the thermal performance test of the HGD. The HGD test section with a triple tube structure includes an inner heater, a HGD model and a cold-hot gas mixer. A counter-flow of cold and hot helium gas under the pres- sure of about 3.0 MPa and the minimum temperature of 100℃ in the annular passage and the maximum of 950℃ in the central tube of the HGD model was formed.
