Abstract

A simulation model for estimating flaw densities and size distributions for welds in nuclear piping is described. Application of the simulation model provides a basis for estimating flaw densities and size distributions as a function of pipe wall thickness, type of piping material, welding procedure, and inspection practice. Trends from the calculations described in this paper are believed to give reasonable inputs for calculating piping failure probabilities. In addition, the flaw simulation model provides a physical basis for scaling flaw distribution parameters between piping of different sizes and fabrication practices, and thereby provides confidence that calculated values of failure probabilities reflect correct trends for a risk-informed ranking process of selecting locations for inservice inspection.
