Monaco - Functional Module

Monaco is a general-purpose, fixed-source, multi-group Monte Carlo shielding code for the SCALE package. It is a functional module that uses already processed AMPX cross sections to calculate neutron and photon fluxes to geometry regions and to point detectors outside the geometry. Basic, multi-group transport methods are inherited from Monaco’s predecessor, MORSE. Variance reduction includes source biasing and weight windows, either by geometry region or by using a mesh importance map. User input includes the cross section file unit number; the geometry description using the SCALE General Geometry Package; source description as a function of position, energy, and direction; tally descriptions (fluxes in which regions, at what point detectors, or over what mesh grids); and response functions (functions of energy). Output consists of tables detailing the region and point detector fluxes (and their responses), as well as files for mesh tallies.
