title = "EFFECTS OF THE BUBBLE SIZE DISTRIBUTIONS ON THE DECONTAMINATION FACTORS DURING BUBBLE RISE IN THE POOL SCRUBBING",
abstract = "In this paper, with the size distribution of the bubbles during pool scrubbing obtained from EPRI experiments, we propose a calculational method for bubble-size-dependent decontamination factors for more realistic analyses on the pool scrubbing coupling with bubble hydrodynamics and thermodynamics. We implement the calculational method into an in-house code named I-COSTA (In-Containment Source Term Analysis). We then perform sensitivity analyses of the bubble size on the various retention mechanisms of the aerosol particles in pool scrubbing. We also perform sensitivity analyses on the size distributions of the bubbles obtained from experiments with various conditions on the diameters at the nozzle exit, molecular weights of non-condensable gases in the carrier gases, and steam fractions of the carrier gases. We apply I-COSTA to analyses of LACE-ESPA{\~N}A experiments and compare the numerical results to those from SPARC-90 and experimental results in order to validate the calculational method and show the effect of the bubble size distributions.",
