Open publisher page 5 citations

Abstract

Nuclear power plants are designed to prevent the damage of safety installations and human safety due to the jet impingement when a pipe is ruptured. We have investigated evaluation methods for the design basis of protection of plants against effects of postulated pipe rupture using computational fluid dynamics analysis (CFD). The flashing steam jet was evaluated in this study. Shapes of flashing jet were obtained by CFD calculations, and we have found that the affected region was wider than usual steam jet flow and strongly depends on the nozzle exit flow conditions. This is thought as the different tendency from established standards.
