| Abstract: | During the operation of a domestic nuclear power plant,turbine blade fracture occurred.This paper analyzes the reason why the defects can not be completely detected by understanding the stress condition of the blade during operation and the defect area of the blade.Through the comparative test method,the optimal penetrant inspection process is improved and determined,which has achieved good results in the overhaul of nuclear power plant. |

| Keywords: | analysis of blade stress defect area of blade penetration inspection |
