Passive advanced pressurized water reactor coolant pump installation technology

The invention relates to a passive advanced pressurized water reactor coolant pump installation technology. The passive advanced pressurized water reactor coolant pump installation technology is characterized in that a main pump occasional passage is provided; before a main pump is introduced to a nuclear island workshop, butt joint between a flat car transporting the main pump and the main pump occasional passage is completed; a draw gear is used to introduce a main pump/transport towing bracket assembly embarked on a mobile device to the nuclear island workshop; during the drawing process, a tail slipping device is used to prevent the moving speed becoming too fast, and then the main pump is moved to a turnover initial position; a ring crane hook is lifted and coordinates with moving of the mobile device so as to turnover the main pump, and at the same time, a tow rope of the tail slipping device is adjusted; the main pump is lifted to a steam generator cavity, and is located in a main pump installation mec
