The helium circulator is a key component of the 10MW High Temperature Gas cooled Reactor (HTR 10), which provides pressure rise required for helium circulation within the primary system in order to assure the thermal energy transfer from the reactor core to the steam generator. The circulator operates at 250℃, 3.0 MPa helium condition. The performance test was carried out in the factory. Instead of 3.0 MPa helium, 0.426 MPa nitrogen was chosen as test fluid to reduce system pressure of the experimental facility. This paper highlights the test principle, describes the test procedures and analyzes the test results. In addition, the circulator performance on the HTR 10 is predicted. As a result, the aerodynamic performances of the helium circulator satisfy the HTR 10 operation requirements with a considerable margin.
