概要
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 two phase flow.
