Evaluation Method for Pipe Wall Thinning Due to Liquid Droplet Impingement - (II) Comparison of Calculations with Measurements at Actual Nuclear Power Plants

Abstract

The validations on DRAWTHREE-LDI are made through the comparisons of results calculated with those measured in feedwater heater vent lines at an actual power plant. In DRAWTHREE-LDI, pipe wall thinning rates are evaluated by the procedure composed of six steps. Comparison of calculated results by DRAWTHREE-LDI is made with those measured in feedwater heater vent lines at an actual power plant. Most calculated results agreed with those measured within a factor of two which is the target in the development of DRAWTHREE-LDI.
