Safety assessments and environmental impact statements for facilities require an estimation of airborne releases from accidents. Aerosols generated by accidents are being investigated to develop the source terms for these releases. One example of a severe accidental release event is a pressurized liquid release. Pressurized liquid release experiments performed in static air measured the mass airborne as a function of source size and containment pressure. Pressurized releases with the containment breach above the liquid level were investigated. For this configuration, only containment pressure at the time of release was found to be a significant parameter. Releases in static air can be estimated using the relationships developed in this work. Weight percent of the airborne source ranged from 4 X 10(-4) to 0.15%. All of the pressurized releases produced a significant fraction of respirable particles.
设施的安全评估和环境影响声明需要估算事故中的空气传播释放量。正在对事故产生的气溶胶进行研究，以确定这些释放的源项。严重意外释放事件的一个例子是加压液体释放。在静态空气中进行的加压液体释放实验测量了作为源尺寸和容器压力函数的空气传播质量。研究了容器液位上方有破损的加压释放情况。对于这种配置，发现仅释放时的容器压力是一个重要参数。静态空气中的释放量可以使用本研究中建立的关系进行估算。空气传播源的重量百分比范围为4×10(-4)至0.15%。所有加压释放都产生了很大一部分可吸入颗粒。
