Vertical Disruption Events (VDE) in tokamaks, may cause significant melting along tile ridges of the vessel upper dump plates with release of metallic particulate and droplets as shown in and in references therein. Accurate studies of the motion of such debris released in the vessel are important for the inventory of tritiated composites in a reactor. Recently numerical codes have been developed to track this particulate of variable mass and charge, in interaction with the Scrape-Off layer (SOL) plasma. Here a contribution is given for a more consistent discussion of the additional acceleration of the dust due to asymmetric loss of mass in flight. A simplified description is constructed in analogy with the physics of comets.

托卡马克中的垂直破裂事件（VDE）可能会导致沿容器上部卸料板的瓦脊明显熔化，并释放金属颗粒和液滴，如其中和参考文献中所示。准确研究容器中释放的此类碎屑的运动对于反应堆中ated化复合材料的库存非常重要。最近，已经开发出数字代码，以与刮擦层（SOL）等离子体相互作用来跟踪质量和电荷可变的颗粒。在此，对于由于飞行中质量的不对称损失而引起的附加尘埃加速度的更一致的讨论做出了贡献。类似于彗星的物理学构造了一个简化的描述。
