Comparison of observed and predicted sodium air and ground concentrations
As part of the US DOE LMFBR safety effort, a project is underway to estimate the uncertainty associated with the use of mathematical models for the assessment of health impacts associated with potential releases of toxic substances to the environment. One facet of this project is the investigation of dispersion in the atmosphere of aerosols of sodium, the proposed coolant for the LMFBR. The Gaussian plume atmospheric diffusion model is the most widely used approach for modeling the atmospheric concentration and deposition of aerosols. Purpose of this paper is to compare predictions from one implementation of the Gaussian plume model with actual measured air and ground concentrations for sodium aerosols released to the atmosphere. The observed values used come from seven atmospheric sodium release tests conducted during 1978 and 1979. Spray and pool fires were used to produce sodium oxide particles under a limited number of atmospheric conditions. The concentration in air, aerial ground deposition, particle size, and chemical composition of the resulting aerosol were examined at downwind distances less than 3200 m.
