The liquid penetrant inspection is required for the weld of tube-tube sheet in steam generator product which was used in the main system of the pressurized water reactor nuclear power plant nuclear island. The selection of liquid penetrant inspection method, the requirements for the inspection devices, and the verification of inspection sensitivity were investigated. Through experiment comparison analysis, the inspection control process for water-washed liquid penetrant inspection of densely arranged tube-tube sheet welds was determined. Moreover, the product inspection results showed that when the liquid penetrant inspection was performed using the densely arranged and numerous tube sheet welds, the most efficient inspection method was the water-washed type dye penetrant inspection method under the condition that the sensitivity requirements were met.
