The Helium circulator is a unique high speed rotating component in the Very High Temperature gas-cooled Reactor(VHTR) which is a candidated nuclear reactor for hydrogen production. Control of gaseous impurities in the VHTR is a significant operating requirement. The oil vapor induced by a circulator will contaminate and damage the sophisticated high temperature components composed of Graphite material. Therefore, Helium circulator needs an elimination of the oil systems required by traditional bearing designs. An oil less magnetic bearing circulator could meet the requirement for VHTR, because the control object in the magnetic bearing system enables the rotor to rotate without any physical contact by using magnetic force. We study the status of magnetic bearing technology and pick out possible problem when the large size helium circulator adapted the magnetic bearing as his bearing system.
