摘要

事故工况下，安全壳内已经沉降的气溶胶由于气流扰动等原因可能发生再悬浮现象，文章中基于STORM(Simplified Test Of Resuspension Mechanism)实验结果对气溶胶再悬浮力学平衡模型适用性进行评估。针对实验建立分析模型，研究了Wichner力学平衡模型中扰动力系数、沉积表面粗糙度和Michael力学平衡模型中沉积表面微凸体之间的距离的影响。通过对比分析模型预测结果与实验测量结果，评估模型的适用性。结果表明：Wichner力学平衡模型更适用于预测气溶胶粒径较小时，较大扰动气流速度区间内的再悬浮行为。

Abstract

Background

During a severe nuclear reactor accident

the aerosol deposited in the containment may resuspend due to airflow disturbance. It would increase the source terms in the containment and may eventually result in an increase in source terms that are released into the environment.

Purpose

This study aims to analyse the applicability of aerosol resuspension force balance models based on the STORM (Simplified Test Of Resuspension Mechanism) experiment.

Methods

Firstly

the analytical model of the experiment was established

and then the influence of the disturbing force coefficient

the deposition surface roughness in the Wichner model and the micro-protrusions distance in Michael model on the deposition surface were studied. The applicability of the models was evaluated by comparison between models prediction results and the experimental measurements.

Results & Conclusions

Analysis results show that the Wichner force balance model is more suitable for predicting the resuspension behavior in a wide range of disturbed airflow velocity with small aerosol particle size.
