Abstract: Sustainability includes all aspects of the society, such as civil infrastructural systems, energy, environment, health, safety, life-cycle analyses, etc. New technologies like nano technology, simulation and smart materials play key roles in achieving sustainability. Nuclear energy is a viable source of clean energy. The historical perspective, R&D, challenges and barriers for sustainability are presented. Key elements include mechanics, life-cycle performance, smart materials, durability, nano and other new technologies. Many complex materials require multi-scale and/or multi-physics research to connect structure to properties and ultimately to function. The amalgamation of the discrete multiple length spectrum and its multiple physics principles creates a unprecedented area whose evolution can only be unveiled through the marriage of advancement of theoretical studies, use of computational methods, and experimental validation. Here we introduce a concurrent multiscale simulation method, aiming at a seamless transition from the atomistic to the continuum description of multi-element crystalline solids. We adopt a cluster-based summation rule for atomic force calculations in the FE formulations.
