Spark Plasma Sintering for Ultra-High Temperature Reactor
Applications," Department of Energy (FY2009 NE-UP Program),
Project Period - 10/1/2009 to 9/30/2012:
A number of W-Re alloys will be developed using a combination of
high energy ball milling and spark plasma sintering.
Microstructures, mechanical properties and thermophysical
properties will be evaluated to study their suitability as the
cladding materials for space nuclear reactors to be used for
space missions to Moon, Mars and beyond. This research will be
mainly carried out at the Center for Advanced Energy Studies (CAES),
Idaho Falls. Our collaborators in this effort are the Boise
State University, Idaho National Laboratory and Center Space

PI, "Mechanical Properties of Nuclear Fuels," supported by the INL / Battelle Energy Alliance,
Project Period - 8/25/2008 to 9/30/2011: Research is being
carried out by a Ph.D. student at the Idaho National Laboratory.
He is using a variety of mechanical characterization techniques to irradiate low enrichment uranium-based fuel materials,
fuel cladding materials, and
evaluating their microstructural characteristics and mechanical
properties before and after irradiation using various test techniques.
Co-PI, "Influence of Fast Neutron
Irradiation on the Mechanical Properties and Microstructure of
Nanostructured Metals/Alloys," ongoing project, UI is a collaborator in the NC
State-led team for the first ATR National Scientific User
Facility (NSUF) grant in April 2008. Under this program, our team
will carry out neutron irradiation experiments on nanocrystalline materials and nanostructured steels to various
neutron doses at the ATR facility of INL. Post-irradiation
examination will be carried out onsite at INL, and cold samples
will be studied at the universities.

Partnership) Research and Training at University of Idaho,"
Department of Energy, Project Period:
An STA equipment was
procured from NETZSCH. With this instrument, one can perform very high temperature (up
to 1773 K) DSC, DTA and TGA (thermogravimetric analysis)
experiments on a variety of materials under a controlled atmosphere. The heating and cooling
rates are programmable and the data acquisition system is fully
automated. This system was used for thermal analysis of
advanced cladding and structural materials. We gratefully acknowledge the financial support of the US
Department of Energy through the grant DE-FG07-07ID14873 for
carrying out this project.
