Abstract

The invention relates to the technical field of reactor engineering, in particular to a detecting positioning device for a spherical element. The device comprises a pressure bearing housing, an innercomponent and a performing component, wherein the pressure bearing housing comprises a box body, a sphere feeding connecting pipe and two sphere discharging connecting pipes; the sphere feeding connecting pipe and the two sphere discharging connecting pipes are correspondingly arranged on the box body; the inner component is arranged in a rotor sunken hole and comprises a lined ring and a limitingring; the performing component comprises a turntable and two supporting lugs. The device can perform automatic material separating, accurate positioning and directional conveying of the spherical element; the device is compact in structure, and simple to control, and meets the requirement of running reliability and maintainability under long-term intermittent running in a high-radioactivity environment.

Description

technical field [0001] The invention relates to the technical field of reactor engineering, in particular to a spherical element detection and positioning device. Background technique [0002] The pebble bed high-temperature gas-cooled reactor uses spherical fuel elements to pass through the core multiple times to achieve non-stop continuous operation. The operation of the fuel loading and unloading system will directly affect the reactivity of the reactor. The online burnup measurement device measures the burnup of the fuel elements unloaded from the core, the components that have not reached the target burnup are sent back to the core, and the spent fuel elements that have reached the target burnup depth are discharged into the spent fuel storage tank. The HTR-10 high-temperature gas-cooled experimental reactor is equipped with a riser downstream of the broken ball separator to cooperate with the burnup measurement device to measure the burnup. The lifter performs the dual...
