title = "Multigroup data processing for the embedded self-shielding method in SCALE",
abstract = "The embedded self-shielding method (ESSM) was previously developed to provide an integrated approach for lattice calculations. ESSM consists of three interrelated components: (1) processing multigroup cross sections, (2) computing resonance-shielded multigroup cross sections, and (3) performing neutron transport calculations in lattice physics calculations. The self-shielding computation in ESSM is embedded within the transport solution, which provides information for treating heterogeneous self-shielding effects. The resulting shielded cross sections provide data for the transport calculation. This approach integrates the self-shielding and transport components of the lattice physics calculations. Earlier publications have described this aspect of ESSM; however, another equally important aspect of ESSM is that the processing of the multigroup cross section library is integrated with the self-shielding procedure in a consistent manner. This paper describes the procedures that have been developed to generate multigroup libraries for ESSM calculations of light water reactor lattices with the SCALE code system. Results of sample lattice physics calculations are presented to illustrate the impact of ESSM processing procedures.",
