Waste tank deflagration source generation mechanisms

PDF Version Also Available for Download.

Description

This paper describes the models employed and analyses performed to estimate the source terms which would result from deflagrations in waste storage and processing tanks at the Savannah River Site (SRS). It should be noted that SRS waste tank deflagrations are very low probability events. The three main source generation mechanisms associated with waste tank deflagrations are: (1) entrainment from the liquid surface, (2) vaporization from the liquid surface, and (3) solids fire ignited as a result of the deflagration. The results of this work show that entrainment would be the dominant source term generation mode for cases where the ... continued below

Description

This paper describes the models employed and analyses performed to estimate the source terms which would result from deflagrations in waste storage and processing tanks at the Savannah River Site (SRS). It should be noted that SRS waste tank deflagrations are very low probability events. The three main source generation mechanisms associated with waste tank deflagrations are: (1) entrainment from the liquid surface, (2) vaporization from the liquid surface, and (3) solids fire ignited as a result of the deflagration. The results of this work show that entrainment would be the dominant source term generation mode for cases where the liquid waste solution level is near the vent path. Vaporization would be the dominant mode for cases where the liquid level is lower. The maximum vaporization source term is approximately an order of magnitude less than that maximum entrainment source term. The source term associated with a solids fire would be insignificant in comparison.
