Local Collection and Treatment of Laser Generated Decontamination Fume

与其他机械或化学技术相比，在核退役任务（去污染或切割）中使用激光技术可以提供显着的优势。优点包括提高安全性，减少下游污水处理要求，减少切割时间/成本。在这些应用中使用激光技术的犹豫主要包括对过程中释放的颗粒和烟雾副产品的担忧。确保足够的萃取和中和副产物对过滤系统提出了很高的要求。它们还可能对人类健康构成严重风险，而且无法加以消除。因此，尽管激光切割具有优势，但目前很少用于核退役，尽管兴趣正在增长。这项研究背后的动机是通过推进局部抽提通风背后的科学技术来提高激光技术作为退役工具的可行性，从而减轻设施通风系统的负担。

Using laser technologies during nuclear decommissioning tasks (decontamination or cutting) can offer significant advantages compared to alternative mechanical or chemical techniques. Advantages include improved safety, reduction in downstream effluent treatment requirements, reduced cutting time/cost. Hesitation to use laser technologies for these applications principally includes concerns surrounding particle and fume by-products liberated during the processes. Ensuring adequate extraction and neutralisation of by-products places heavy demand on filtration systems. They also potentially pose serious risks to human health without abatement. Hence, despite its advantages, laser cutting is seldom currently used for nuclear decommissioning, although interest is growing. The motivation behind this study is to increase the viability of laser technology as a decommissioning tool by advancing the science and technology behind local extract ventilation, therefore reducing the burden on facility ventilation systems.
