Title: A comparison of results from LANCER02 and MCNP on a series of two-dimensional multiple BWR bundle configurations

This paper discusses recent extensions to the LANCER02 lattice physics code that allow for the analysis of multiple bundles lying along a two-dimensional plane of a reactor core. The paper presents results from LANCER02 on a study consisting of analyses on single assemblies, 2 x 2 arrays of bundles, and 4 x 4 arrays of bundles at different operating conditions. LANCER02 eigenvalues and rod-by-rod fission rates are compared against results from corresponding MCNP analyses. Results indicate that the LANCER02 multi-bundle modelling option is equivalent in accuracy to its single-assembly capability. (authors)
