AI Technical Summary
Existing technologies struggle to efficiently obtain complete circumferential oxide film thickness distribution information for fuel rods, and scum interference with measurement signals affects data accuracy.
A device for measuring the oxide film thickness of fuel rods inside a hot chamber was designed, comprising a support structure, a limiting structure, and a driving structure. By moving multiple sets of measuring structures along the fuel rod axis, combined with eddy current detection technology and a gas cleaning ring, the continuity and stability of the measurement are ensured.
It enables continuous and stable measurement of the oxide film thickness of fuel rods, improves measurement efficiency and accuracy, and avoids the influence of scum on the measurement results.
