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).
Europe is considering the viability of a next generation of nuclear energy systems that promise significant advances in sustainability, safety, reliability and costs. An EU initiative aims to deploy one such nuclear reactor prototype in central Europe.
