The purpose of this report is to establish a predictive methodology for estimating rate of wall thinning in a piping system used in ag eing nuclear power plants. First, mechanism of flow accelerated corrosion caused by steam of flowing water is given by KWU-KR model. Se condly, a method for setting geometrical parameter based on pipe wall thickness measurements is considered. Thirdly, estimation method ology for wall thinning rate is formulated within the framework of Kalman filtering. Finally, some simula...
