Abstract In this paper, from a review of the size distribution of the bubbles during pool scrubbing obtained from experiments by EPRI, we apply the bubble size distributions to analyses on the decontamination factors of pool scrubbing via I-COSTA (In-Containment Source Term Analysis). We perform sensitivity studies of the bubble size on the various mechanisms of deposition of aerosol particles in pool scrubbing. We also perform sensitivity studies on the size distributions of the bubbles depending on the diameters at the nozzle exit, the molecular weights of non-condensable gases in the carrier gases, and the steam fractions of the carrier gases. We then perform analyses of LACE-ESPANA experiments and compare the numerical results to those from SPARC-90 and experimental results in order to show the effect of the bubble size distributions.

用 EPRI 实验获得的气泡尺寸分布对水池洗涤过程中的去污因素进行初步分析

摘要 本文从 EPRI 实验中获得的水池洗涤过程中气泡大小分布的回顾，我们应用气泡大小分布通过 I-COSTA（In-Containment Source Term Analysis）分析水池洗涤的去污因素。 ）。我们对水池洗涤中气溶胶颗粒沉积的各种机制进行气泡大小的敏感性研究。我们还根据喷嘴出口处的直径、载气中不可冷凝气体的分子量以及载气的蒸汽分数对气泡的尺寸分布进行敏感性研究。然后我们对 LACE-ESPANA 实验进行分析，并将数值结果与 SPARC-90 和实验结果进行比较，以显示气泡尺寸分布的影响。
