What Simulations need to be done for the VTR?
Part of the VTR mission will be to provide experimental and computational advances in nuclear and materials science by enabling a comprehensive understanding of nuclear fuels as well as structural materials to support the development of advanced nuclear energy systems. ISU has an opportunity to play a role in the development of a VTR program for material irradiation testing. Such a testing program will have a research component that utilizes computational advances to benchmark models of materials that have been exposed to the fast neutrons produced by the VTR. We propose a program to design model validation experiments that characterize microstructure before and after irradiation.
Specifically nuclear fuel cracking as a result of irradiation will be a focus of the VTR based validation program using INL's simulation tool MARMOT. The initial step of this research program will be to develop a validation experiment. The validation experiment will focus on methods to measure local phenomena changes that avoid observing averaged microstructure properties. Most of the available data reports the results of average microstructural properties over long time periods. We propose to development a validation experiment using MARMOT that will characterize microstructure changes in 3D over short time periods.

ISU currently has a physics student working as an intern with the MOOSE software development group. The student is focusing on how ions, like fission fragments, loose their energy traversing materials like fuel rods. The student's current research involves altering the packages within MARMOT to use different physical descriptions of energy loss that are highly dependent on fragment kinematics. After the internship is completed later this year and with the support of this proposal, the student will move onto using MARMOT to develop a 3-D description of the damage done to a fuel which would result in cracking. Armed with this experience, the student can design experiments that would be used to validate the predictions of MARMOT. The skill sets received in advanced computer and development are in high demand and would easily enable the student to successfully enter the technical work force.

Involvement in MOOSE INL group
ISU currently has a student who is an intern with INL's software development group. This may be a well timed opportunity to build a program utilizing INL's investment in new computing resources. ISU's physics department has been focused more on the Idaho Accelerator Center and Jefferson Lab. With the support of this proposal, ISU's physics department can build upon its limited relationship with INL by becoming more involved in INL's advanced computing initiatives. From our perspective, INL's new computer center will be the central hub to strengthen ISU-INL collaborative research.

Describe simulations here
MARMOT's 3-D description of the damage done to irradiation fuel will be used to develop validation experiments. The first step of the program will be to visual the temporal damage, in three dimensions, to a fuel rod that is exposed to neutrons from the VTR. The second step will be the development of a validation experiment based on MARMOT's predictions. The key ingredients of the experiment will be non-destructive characterization that can use the Physics department's current tools of non-destructive analysis such as photon activation analysis or positron annihilation spectroscopy.
