摘要/Abstract

摘要： 为减少核设施运行、检修等过程产生的放射性气溶胶对人员和环境的危害,方便对放射性气溶胶颗粒进行回收处理,以丙烯酸丁酯、甲基丙烯酸甲酯和甲基丙烯酸为单体,通过乳液聚合法制备了成膜型雾化固定剂。对固定剂进行了基础性能表征及气溶胶控制实验,结果表明,该雾化固定剂在300 mL/m³的用量时针对二氧化钛粉末2小时捕集率达到95%以上,且再悬浮率仅为0.2%。在某后处理厂手套箱检修时对该固定剂进行了现场应用试验,其在30 min内对检修过程一级气帐内的放射性气溶胶控制效率达到了95%。因此,该成膜型雾化固定剂可应用于核设施运行及检修场景的放射性气溶胶控制,能够有效捕集气溶胶并防止其再悬浮。

Abstract: To reduce the hazards of radioactive aerosols to personnel and the environment during the operation,maintenance and other activities of nuclear facilities, and to facilitate the recovery and treatment of radioactive aerosol particles, a film-forming atomized fixative was prepared via emulsion polymerization with butyl acrylate, methyl methacrylate and methacrylic acid as monomers. The fixative is used to capture and suppress radioactive aerosols, so as to mitigate the diffusion and resuspension of aerosols. Fundamental characterization and aerosol control experiments were performed. The results demonstrate that the fixative achieves a 2-hour capture efficiency of over 95% at a dosage of 300 mL/m³, with a resuspension rate of merely 0.2%. Field tests were further conducted in a reprocessing plant, showing that the control efficiency of fixative for radioactive aerosols in the first-level gas bladder reached 95% within 30 minutes during overhaul and maintenance. Accordingly, this film-forming atomized fixative exhibits excellent performance for radioactive aerosol control in nuclear facility maintenance, achieving efficient capture and significant inhibition of resuspension.
