[0002] In the spent fuel reprocessing plant, some special equipment is installed in the hot chamber (red zone), and power and signals need to be transmitted through penetrations and cables in the hot chamber. After long-term operation, due to the high radiation level in the hot chamber, maintenance personnel cannot directly enter the hot chamber to perform continuous maintenance on the equipment. This requires that some parts of the equipment in the hot chamber have the function of remote disassembly and assembly. The hot chamber only has a small inspection well for the inspection and maintenance of the cable drag chain, and the inspection well is located at the top of the hot chamber, far away from the equipment, which makes it difficult to disassemble and assemble the equipment at a distance. The cable drag chain used for the equipment in the hot chamber is long and heavy, making it difficult to reinstall after maintenance. There is no effective traction device, and it can only be transported by personnel in the hot chamber inspection well through long-pole tools. The work efficiency is low and the personnel are in the high radiation zone for a long time, which greatly increases the exposure of personnel. During the reinstallation process, the drag chain has no effective support or guidance inside the hot chamber, and there is a risk of the cable drag chain breaking, which makes the drag chain unable to be used normally and needs to be replaced and reinstalled.
