Abstract: This paper introduces the main technology and implementation process of a pipe wall thickness management system in nuclear power plant. The system can realize the information storage by establishing the pipeline basic information and thickness measurement database of the conventional island system of the power plant, and realize the visual display of the current situation of pipeline wall thickness reduction by combining virtual reality three-dimensional visualization technology. According to the existing thickness measurement data of previous overhauls of the power plant, the wall thickness reduction trend analysis and prediction are realized through a feasible mathematical calculation model, so as to promote the information construction of the pipeline data of the secondary circuit FAC system, and solve the problems of low efficiency and easy leakage in evaluating the wall thickness reduction of secondary circuit pipeline and calculating the corrosion rate of components in power plant.
