Sensitivity analysis of the HAARM-3 code

Battelle's Columbus Laboratories has recently developed and completed an improved computer model for predicting LMFBR aerosol behavior within the containment. This model is designated HAARM-3 (Heterogeneous Aerosol Agglomeration Revised Model-3). One of the important improvements incorporated in the HAARM-3 code compared to the previous models is that the effects of morphological properties of agglomerates (density, size, and shape) have been comprehensively corrected. Aerosol agglomeration mechanisms due to gas turbulence which had not been included previously has also been added into the HAARM-3 code. These HAARM-3 calculations have been compared with available experimental data and found to predict aerosol behavior more realistically. The report develops a methodology to perform sensitivity analysis of the HAARM-3 computer code and studies quantitatively the effects of various independent variables of the code such as initial aerosol properties and containment geometry upon aerosol behavior
