Abstract

The evolution of a complex criticality model for a burnup credit shipping cask to an accurate TSUNAMI-3D model for eigenvalue sensitivity coefficient generation is detailed in this paper. TSUNAMI-3D is a Monte Carlo-based eigenvalue sensitivity analysis sequence that was released with SCALE 5. In the criticality model, 32 fuel assemblies, each with 18 axial zones with differing depletion-dependent compositions, are placed in a generic burnup credit cask, referred to as the GBC-32, in a fully flooded condition. The selection of various combinations of options for TSUNAMI-3D and their effect on computational requirements and the validity of the sensitivity coefficients, relative to direct difference calculation results, are described. Accurate modeling of this system required the use of prototypic codes developed for the next release of SCALE.
