Multiple discharge cylindrical pump collector

Patent ·
OSTI ID:7261822
This patent describes an improvement in a method for circulating fluid coolant through a reactor core of a pool-type nuclear reactor having a sealed containment vessel containing a reactor core submersed in a body of liquid coolant. The method for circulating coolant including utilization of a rotary pump including an impeller for producing a highly circumferential flow of cooling fluid and a method for collecting and discharging coolant fluid, the improvement to the method of collecting and discharging coolant fluid including the steps of: producing a substantially uniform circumferential flow of the fluid by directing the flow through a plurality of diffuser vanes and into an annular collector located radially outboard from the impeller. The annular collector having an entirely closed outer periphery; and turning the flow of cooling fluid into a substantially axially direction while maintaining a substantially constant average flow velocity by directing the coolant flow from the annular collector into a plurality of individual passageways located in an axial position relative to the annular collector.
