title = "Development of a new 47-group library for the CASL neutronics simulators",
abstract = "The MPACT neutronics module of the Consortium for Advanced Simulation of Light Water Reactors (CASL) core simulator is a 3-D whole core transport code being developed for the CASL toolset, Virtual Environment for Reactor Analysis (VERA). MPACT is under development for neutronics and thermal-hydraulics coupled simulation for pressurized light water reactors. Key characteristics of the MPACT code include (1) a subgroup method for resonance self-shielding and (2) a whole core solver with a 1-D / 2-D synthesis method. Oak Ridge National Laboratory (ORNL) AMPX/SCALE code packages have been significantly improved to support various intermediate resonance self-shielding approximations such as subgroup and embedded self-shielding methods. New 47-group AMPX and MPACT libraries, which are based on ENDF/B-VII.O, have been generated for the CASL neutronics module MPACT. The MPACT group structure comes from the HELIOS library. This new 47-group MPACT library includes all nuclear data required for static and transient core simulations. This study discusses a detailed procedure to generate 47-group AMPX and MPACT libraries and benchmark results for VERA progression problems.",
