Abstract

The analysis of VHTR fuel tends to be difficult, when using deterministic methods currently employed in lattice codes, notably because of limitations on geometry representation, and the stochastic positionning of spherical elements. The method proposed here and implemented in the lattice code DRAGON is to generate the positions of multi-layered spheres using random sequential addition, and to analyze the resulting geometry using a full three-dimentionnal spherical collision probability method. The preliminary validation runs are consistent with results obtained using the Monte-Carlo method. Comparisons have also been made with two double-heterogeneity models already available in DRAGON.
