Abstract

The invention discloses an automatic detection mechanism for appearance integrity of a ball bed high-temperature reactor fuel element, belonging to the field of reactor engineering equipment. The automatic detection mechanism comprises a rack, a detection module, a clamp module, a clamping rotation module and an element guide rail module. The automatic detection mechanism can realize the accuratepositioning of a novel fuel element, the effective clamping and the sufficient rotation, and finishes twice automatic detection processes of the element, thus being applied to detect the appearance integrity of the automatic detection mechanism.

Description

technical field [0001] The invention relates to the field of reactor engineering equipment, in particular to an automatic detection mechanism for the appearance integrity of fuel elements of a pebble bed high temperature reactor. Background technique [0002] The high-temperature gas-cooled reactor has the characteristics of continuous circulation of fuel elements and non-stop refueling. The fuel used is a spherical element with a diameter of 60 mm. A certain amount of new fuel needs to be added to the core every day, and a corresponding amount of spent fuel. After the fuel elements are processed and manufactured, they are transported outside the plant to the nuclear power plant for use. Due to the bumps and operations in the transportation and hoisting process, the appearance integrity of the new fuel elements may be damaged. In order to avoid damage, the new fuel elements that exceed the standard are loaded into the core , requiring visual integrity checks of components d...
