Abstract
Stoichiometric circular shaped interstitial dislocation loop energies are calculated in stoichiometric UO2 by empirical potential simulation. The Burgers vector directions studied are ã110ã and ã111ã. The main structural properties of each type of interstitial dislocation loop are determined, including stacking fault energy. Defect energies are compared and a maximum size for stable ã111ã dislocation loops before transition to ã110ã dislocation loops is given. A model of dislocation loop energy based on elasticity theory is then fitted on the basis of these simulation results.
