description The invention belongs to the technical field of pressurized water reactor nuclear power station reactor upper reactor internal control rod guide cylinder assemblies and specifically relates to a fielddisassembling and assembling process of upper reactor internal control rod guide cylinders in order to overcome the physical condition restrictions. According to the field disassembling and assembling process of the upper reactor internal control rod guide cylinders, provided by the invention, related tools are used in cooperation to disassemble and assemble the guide cylinders in the designatedpositions of upper reactor internals. The field disassembling and assembling process is characterized by comprising the steps of dismantling of guide cylinder fastening bolts, dismantling of the upperguide cylinder, dismantling of the lower guide cylinder, reinstallation of the lower guide cylinder, reinstallation of the upper guide cylinder and installation of the guide cylinder fastening bolts.Through the field disassemb
