> TRISO particles. Each of these small particles (which are about the size of a poppy seed) is comprised of uranium, oxygen and carbon covered by ceramic and carbon materials. The particles are then formulated into larger cylinders or spheres (depending on the reactor design) for use in reactors.
This sounds quite much like the PBMRs (pebble bed modular reactors) proposed by Eskom (IIRC). The primary technical objection to those was the risk of a graphite fire, which could be VERY difficult to extinguish. Does this new technology under discussion here have any similar risk(s) ? 3000F - is that sufficiently hot for testing purposes ?
