For application of the FAC code to system safety analysis, a 1D FAC code was developed by applying 1D mass transfer coefficients and geometry factors, which could prepare for not only the probability of serious wall thinning occurrence but also a hazard scale for pipe rupture could be analyzed. FAC risk was defined as the mathematical product of the possibility of wall thinning occurrence and its hazard scale. The local maximum thinning rate could be predicted with accuracy within a factor of 2 with th...

FAC risk has been defined as the mathematical product of the possibility of wall thinning occurrence and its hazard scale. The possibility of wall thinning occurrence was designated as the time margin for pipe rupture determined by applying a one-dimensional FAC code, which could predict wall thinning rate with an accuracy within a factor of 2, while the hazard scale was defined as the volume of effluent steam and water from the ruptured mouth, which was enthalpy of water originally flowing in the pipe...

In order to establish safe and reliable plant operation, it is required to forecast future troubles on structural materials based o n combined analyses of flow dynamics and corrosion and to mitigate them before they become serious on plant operation. In the prese ntation, discussion is focused on wall thinning of major pipes due to single and two phase flow. FAC (flow accelerated corrosion) is considered for wall thinning in single phase flow, while LDI (liquid droplet impingement) is evaluated for that in...
