| Abstract: | In order to ensure that the installation of AP1000 reactor coolant main pipe meets the design requirements,researches were conducted on the measurement technology,groove preparation and welding deformation control of main pipe.Results show that the laser measurement can completely meet the installation precision control requirement of main pipe.The feed amount for groove machining should not exceed 0.25 mm/time,and the welding deformation of main pipe can be effectively controlled and tracked.Under the guidance of above researches,the installation of AP1000 reactor coolant main pipe can completely meet the design requirements. |
