The experimental study on the helium circulator of HTR-10

The helium circulator is a key component of 10 MW high temperature gas-cool ed reactor (HTR-10), which has the helium coolant circulate inside the prim ary loop of the reactor. Before delivery, the performance experiment of the circulator was carried out in the factory at 0.426 MPa, 250 degreesC nitro gen condition. In the paper, by using dimensional methodology, the experime nt results are converted to those on 3.0 MPa, 250 degreesC helium condition which is real working condition on the reactor. Then the circulator perfor mances are analyzed. Finally, the operating performances on HTR-10 are pred icted. The paper concludes that the circulator design was made correctly an d the performances are satisfied with HTR-10 operating requirements. (C) 20 01 Elsevier Science B.V. All rights reserved.
