S083024 Investigation for Piping Strength on Non Condensable Gas Combustion : Detonation Experiments of Mixed Gas in Various Piping

Abstract

In late 2001, due to rapid combustion of radiolysis gas, steam piping rupture accidents occurred in Japan and abroad BWR plant. In this study, to establish the structural integrity evaluation method for the steam piping in the case of rapid combustion of the radiolysis gas occurs, detonation experiments were conducted using various piping specimens that are assumed in the actual plant. Pressure data in the various piping were obtained for the validation of detonation analysis.
