摘要: Graphite particle generation by interpebble abrasion and of pebbles with the containment vessel during operation a pebble bed reactor is an issue interest in safety analysis this class very high temperature reactor. To understand generation, we have constructed apparatus to generate graphite particles from preformed hemispheres under rotational/spinning abrasive loading. We initially used commercial-grade graphites our experiments generated size distributions for abraded particles, determined shapes, measured surface areas, pore volumes, volume produced surfaces different conditions. The were studied using Aerodynamic Particle Sizer™ Scanning Mobility Sizer.™ Most observed range 18.1 600 nm diameter. scanning electron micrographs showed that tend to...
