摘要

文章介绍了利用 MAVR-TA 代码模拟 TOSQAN（法国）和 CSE（美国）实验中喷雾系统液滴捕获气溶胶裂变产物模拟物的结果。计算结果与实验数据密切相关。描述了在超出设计基础的事故条件下喷雾液滴捕获气溶胶粒子的主要机制。通过分析计算研究了气溶胶颗粒密度对颗粒去除效率的影响。根据计算结果，气溶胶粒子的密度对从安全壳大气中清除这些粒子有重大影响。

Simulation of the removal of radioactive aerosols from the atmosphere of NPP containment by spray system droplets using the MAVR-TA code

The article presents the results of a simulation of the TOSQAN (France) and CSE (USA) experiments on the capture of aerosol fission product simulators by droplets of the spray system using the MAVR-TA code. The calculation results are well-correlated with experimental data. The main mechanisms for capturing aerosol particles by sprayed droplets under conditions of beyond-design-basis accidents are described. Analytical calculations were carried out to study the effect of aerosol particle density on the efficiency of particle removal. According to the performed calculations, the density of aerosol particles has a significant impact on their removal from the atmosphere of the containment.
