Title: A new swelling model and its application to uranium silicide research reactor fuel

Abstract

This document discusses a new version of the dispersion fuel behavior model currently being incorporated in DART, which has been generated. The model's description of fuel swelling - more specifically, the evaluation of fission-gas bubble morphology - is significantly improved. Although some of the assumptions underlying the basic model are derived from systems other than U[sub 3]Si[sub 2], it represents a physically realistic interpretation of the observed irradiation behavior of U[sub 3]Si[sub 2] over a wide range of fission densities and fission rates.
