放射性水洗研究综述

Summary of Research on Radionuclide Pool Scrubbing

摘要: 在核电厂严重事故工况下，水洗对放射性裂变产物的去除起着重要作用。从20世纪70年代，国际上关于放射性物质水洗过滤的研究便已逐步开展，这些研究既包含气泡形成的热工水力学过程和气溶胶去除的试验研究，也包含水洗效果分析模型的开发等理论研究，且主要针对的是沸水堆核电站抑压水池的水洗。本文基于大量的文献调研结果，从试验研究和计算模型开发两个方面，对放射性水洗的研究现状进行了介绍和总结，可为后续放射性水洗模型的研究、优化和验证以及气溶胶水洗试验的设计和开展提供参考。

Abstract: Pool scrubbing could play an important role in the removal of radioactive fission products under severe accident conditions in nuclear power plants. Since the 1970s research on pool scrubbing has been started, comprising the experimental study of the thermal-hydraulics of bubble formation and of the aerosol retention, as well as the development of pool scrubbing models. Such research mainly focused on BWR suppression pool scrubbing. In this paper, based on a large number of literature reviews, status of research on pool scrubbing was introduced and summarized from the point of experimental study and model developing, which could provide a reference for studying, optimizing and verifying pool scrubbing models, as well as designing and performing aerosol pool scrubbing experiments.
