S083014 Research on the hydrogen venting from the BWR reactor building at severe accident : Part 3: Sensitivity analysis on parameters related to hydrogen behavior

Abstract

Hydrogen venting in BWR reactor building (R/B) is an important issue in severe accident management. For this situation, an evaluation method to predict hydrogen density in R/B is proposed with lumped parameter system assuming uniform distribution in R/B space. Sensitivity analyses were conducted with this method to understand the effect of related parameter on hydrogen behavior and venting efficiency.
