KMC Modeling of Helium-Vacancy Clustering in Iron
2011 - 2015
This project looks at the effect of helium on the accumulation of defects and defect clusters in iron. KMC simulations are being used to find the void size distribution in iron under irradiation. This work will concentrate on determining the effect of helium on the void size distribution, and comparing these results to previous experimental data.

Equation of State for Xenon in Molybdenum
2012
This project was focused on directly calculating the equation of state for xenon in molybdenum by Metropolis monte carlo simulation using a recently developed EAM interatomic potential. The SPPARKS KMC code was extended to work with the EAM potential form, and a number of data processing tools were written to help with file format conversion and data analysis.

Fundamental Studies of Irradiation-Induced Defect Formation in Oxide Fuels
2007-2010
This project was set up to address performance issues of oxide-type nuclear fuels in the proposed fast spectrum Advanced Burner Test Reactor (ABTR). Studying radiation effects and fission product transport processes in oxide-type nuclear fuels will establish a fundamental understanding of fuel performance. My focus in the project was the development of a kinetic Monte Carlo simulation code that could model configuration-dependent defect mobility data, which was then used to study the effects of impurity concentration on defect mobility in the surrogate CeO2 material.
