Short summary
Short summary
We present new measurements of the efficiency with which aerosol particles are collected by raindrops. These measurements provide the link to reconcile the scavenging coefficients obtained from theoretical approaches with those from experimental studies. We provide proof of the rear capture that is a fundamental effect on submicroscopic particles. Finally, we propose an expression to take into account this mechanism to calculate the collection efficiency for drops within the rain size range.
Short summary
The decommissioning of nuclear power plants needs the development of innovative cutting tools to improve safety, radiation protection, waste management, time and cost aspects. Laser cutting technology is considered as a promising alternative for the segmentation of nuclear power reactors. LD-SAFE aims to demonstrate that the laser cutting technique applied to dismantling allows meeting technical and safety challenges in a more efficient and economical way than conventional cutting techniques.
