Flow-accelerated corrosion (FAC) of carbon steel piping is a significant problem in nuclear power plants.
The basic process of FAC is currently understood relatively well; however, the accuracy of predictionmodels of the wall-thinning rate under an FAC environment is not reliable. Herein, we propose amethodology to construct pipe wall-thinning rate prediction models using artificial neural networks anda convolutional neural network, which is confined to a straight pipe without geometric changes.
Furthermore, a methodology to generate training data is proposed to efficiently train the neural networkfor the development of a machine learning-based FAC prediction model. Consequently, it is concludedthat machine learning can be used to construct pipe wall thinning rate prediction models and optimizethe number of training datasets for training the machine learning algorithm. The proposed methodologycan be applied to efficiently generate a large dataset from an FAC test to develop a wall thinning rateprediction model for a real situation
