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

[sjlee at cct.lsu.edu]

Dear All,

As a reminder, Steven Zinkle, of Oak Ridge National Laboratory will be  
giving a seminar today, 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.

The seminar will be a live broadcast from Louisiana State University,
