[LA-SiGMA] Reminder - Dr. Steven Zinkle, Friday March 22, 3:30 p.m.

[sjlee at cct.lsu.edu]

Dear All,

Dr. Steven Zinkle, of Oak Ridge National Laboratory will be giving a  
seminar Friday, March 22, at 3:30 p.m. in the Frank H. Walk Design  
Presentation Room at Louisiana State University. The title of his talk  
is "Materials Under Extreme Environments: Fission and Fusion Energy".

Abstract:
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 20% of the US electricity, and 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 be presented.

About the speaker:
Steve is currently the Chief Scientist of the Nuclear Science and  
Engineering Directorate and a Corporate Fellow at Oak Ridge National  
Laboratory. He previously served as the director of the ORNL Materials  
Science and Technology Division from 2006 - 2010, and in a variety of  
research scientist and program management roles since he joined ORNL  
in 1985. He received a PhD in Nuclear Engineering and an MS in  
Materials Science from the University of Wisconsin-Madison in 1985.  
His research interests include deformation and fracture mechanisms in  
structural materials and investigation of radiation effects in  
ceramics, fuel systems, and metallic alloys for fusion and fission  
energy systems. He has written over 240 peer-reviewed publications and  
is a member of the National Academy of Engineering. Steve is a  
recipient of the 2006 U.S. Department of Energy E.O. Lawrence Award,  
and is a fellow of the American Ceramic Society, ASM International,  
The Minerals, Metals and Materials Society (TMS), the Materials  
Research Society, the American Nuclear Society (ANS), and the American  
Association for the Advancement of Science. He received the 2007  
Mishima Award from ANS for outstanding R&D on nuclear fuels and  
materials and received the inaugural Robert Cahn Award from Elsevier  
Ltd. in 2010.
