摘　　要：UF_(6)泄漏会产生兼具化学危害与辐射危害的液滴型气溶胶,人员吸入会造成危害。对气溶胶进行压制是常用控制手段,在常规放射性气溶胶压制剂的基础配方中添加4%的NaCO_(3)等针对UF_(6)特性的专用助剂,研制出具有针对性的气溶胶压制剂。实验设计加工了以压缩空气作动力,以超声雾化喷嘴为主要部件的流体动力型超声雾化装置,选用SiCl_(4)作为模拟试剂,用其模拟UF_(6)泄漏并进行压制试验,结果表明压制剂在1 min内的压制效果达到自然沉降12 h以上的效果。Leakage of UF_(6) can form droplet-type aerosols,causing chemical and radiological hazards to workers.Atomization suppression method to control those aerosols is commonly used.By adding NaCO_(3) and other auxiliaries to the basic formula,a targeted aerosol inhibitor for UF_(6) is obtained.Compressed air is used as the power and an ultrasonic atomizing nozzle is used as the main component of a fluid-powered ultrasonic atomizing device.SiCl_(4) is used to simulate UF_(6) leakage.The results show that the suppression effect of the aerosol inhibitor in 1 minute is equivalent to the effect of 12 hours natural sedimentation.
