STREAM II-V3: Revision for STREAM II-V2 to Include the Sedimentation Effects on a Release from H-Area
STREAM II, an aqueous transport module of the Savannah River Site emergency response Weather INformation Display (WIND) system, accounts for the effects of dilution, advection and dispersion. Although the model has the capability to account for nuclear decay, due to the short time interval of interest for emergency response, the effect of nuclear decay is very small and so it is not employed. The interactions between the sediment and radionuclides are controlled by the flow conditions and physical and chemical characteristics of the radionuclides and the sediment constituents. The STREAM II-V2 used in emergency response does not model the effects of sediment deposition/resuspension to minimize computing time. The effects of sedimentation on cesium and plutonium transport in the Fourmile Branch were studied recently and the results from these studies indicated that the downstream cesium and plutonium peak concentrations were significantly reduced due to the effects of sedimentations. The STREAM II-V2 was upgraded to account for the effect of sedimentation on aqueous transport of cesium and plutonium released from H-Area.
