CAVITY REACTOR WITH TWO STAGE SEPARATION

摘要

A colloidal gas core nuclear reactor having a high tensile strength outer semispheroidal pressure shell enclosing a moderator body member which surrounds a central cavity with an expanding nozzle at one end thereof. The greatest cavity radius is at the end remote from the nozzle. Hydrogen gas is supplied to the cavity to provide a vortex fow within the cavity. A conical duct is provided between the throat of the nozzle and the expansion portion of the nozzle. A groove and particle catcher is provided between the duct and expansion portion of the nozzle. The groove leads to a particle outlet duct.
