Description
A helium circulator, to provide up to 1.5 kg/s of helium flow with pressure of 8 MPa, has been developed for the HCCR-TBS. To overcome the pressure drop of the helium cooling system of the HCCR TBS, the circulator is designed maximum speed of 70,000 RPM with electric power of 150 kWe to meet compression ratio of 1.1. One of the major design features of the circulator is that the impeller and the shaft are mechanically separated to isolate helium coolant pressure boundary from the atmosphere. The rotational momentum of the shaft, however, is transfer to the impeller by the magnetic coupling device. The circulator will be installed in the HeSS facility by May 2016 and the performance test will be performed to verify design parameters and performance of the circulator.
