Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 to 1000 nanometres (10−9 meter) but usually is 1 to 100 nm (the usual definition of nanoscale).
Thermal hydraulics is recognised as key to the development of next-generation reactor systems. EU-funded researchers have developed new physical models and improved numerical analysis tools as well as their application to address cross-cutting issues.
