讲座主要内容:
Development and deployment of a diverse mixture of economic and environmentally sustainable energy sources is important for international energy security. Nuclear (fission) power currently provides about 13% of the worldwide electricity (and is the major contributor to clean energy with low carbon emissions). A variety of fission and fusion energy concepts are under consideration for meeting future energy needs. After a brief review of current and proposed fission and fusion energy systems, the crucial role of high performance materials on possible future pathways for fission and fusion energy systems will be discussed. Key materials science aspects associated with operation in these extreme temperature, mechanical stress and radiation environments will be summarized. Radiation-induced nanoscale complexes that evolve over multiple length and time scales (with the potential for dramatic accompanying property changes) are a recurring feature in many materials systems for nuclear energy. Several strategies to design new high-performance self-healing structural materials will be discussed. Recent exploratory research on potentially improved accident-tolerant fuel systems for fission reactors (motivated by the 2011 accident at the Fukushima Dai-ichi power plants in Japan following the devastating earthquake and tsunami) will also be presented.
