Disassembling of NPP equipment, systems and metal constructions is a compulsory procedure in the final stage of NPPs work cycle, namely withdrawal. Disassembling technology is closely linked with some necessary conditions, that is why some mandatory requirements must be fulfilled.
The disassembling tasks can be carried out with the help of modern tech-nologies, means and instrumentware. The system of task-oriented engineering and adaptation to the environment and its conditions provides informational and me-thodical supporting in the process of developing the technology of equipment dis-assembling.   
This article presents the common methods and practical recommendations for developing the technological process of disassembling of NPP equipment.
