Abstract: Abstract:Taking the final assembly clearance control of the steam seal of the turbine in AP1000 nuclear power unit as example, the characteristics of the laser clearance measurement method and the characteristics of the conventional clearance measurement method were analyzed, and the advantages and disadvantages of the two methods were compared. The laser clearance measurement method was adopted for measuring, and the conventional clearance measurement method was adopted for verifying. So the rationality of the final assembly clearance of steam seal was ensured.
