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.
