[0002] The nuclear fuel is in the form of uranium dioxide ceramic core blocks sintered from uranium mixture powder. The ceramic core blocks are cylinders with a diameter of one centimeter and a height of one centimeter. Hundreds of core blocks are stacked together and loaded into a slender zirconium alloy casing with a diameter of one centimeter, a length of about four meters, and a thickness of about one millimeter. Because the nuclear fission reaction is like burning atoms, it is called a fuel rod.
[0003] At present, most of the existing fuel rods need to be cut during processing to facilitate subsequent processing and packaging, and most of the existing cutting devices rely on a push rod to push the fuel core rod along the slide groove toward the saw blade to achieve cutting. This cutting method does not fix the fuel core rod when in use, which can easily lead to force generated when the fuel core rod contacts the saw blade, causing the fuel core rod to shift or tilt, resulting in changes in the subsequent cutting position or uneven cuts, affecting the normal use of the device.
