Description
The OpenFOAM Fuel BEhavior Analysis Tool, i.e. OFFBEAT, is a research-oriented multi-dimensional fuel behavior solver under development at the Laboratory for Reactor Physics and Systems Behaviour at the EPFL and at the Paul Scherrer Institut, in Switzerland. OFFBEAT relies upon the C++ library OpenFOAM and it aims to be a complement to traditional fuel performance codes for the study of 2D and 3D complex phenomena occurring in fuel rods. Although initially developed for light water reactors, the tool displays a wide flexibility and work is ongoing on its extension to Fast Reactor applications. Among various ongoing developments, this paper presents the integration in OFFBEAT of an accurate fission gas release model. The implementation presented in this report is based on the 0-D inert gas behavior code SCIANTIX, developed at the Politecnico di Milano (Italy) and designed to be coupled with fuel performance codes. The correct implementation of this fission gas release model in OFFBEAT is assessed with validation tests, using experimental data from the International Fuel Performance Experiments (IFPE) database.
