AUS module MIRANDA - a data preparation code based on multiregion resonance theory

Abstract

MIRANDA is a data preparation module of the AUS reactor neutronics scheme and is used to prepare multigroup cross-section data which are pertinent to a particular reactor system from a general purpose multigroup library of cross sections. The cross-section library has been prepared from ENDF/B and includes temperature dependent data and resonance cross sections represented by subgroup parameters. The MIRANDA module includes a multiregion resonance calculation in slab, cylinder or cluster geometry, a homogeneous B. flux solution, and a group condensation facility. Interaction with other AUS modules, particularly for burnup calculations, is provided.
