11. AMPX-6: A Modular Code System for Processing ENDF/B Evaluations

AMPX is a modular system of computer programs used for nuclear analysis with a primary emphasis on tasks associated with the production and use of multigroup (MG) and continuous energy (CE) cross sections. AMPX accepts basic cross section data from ENDF/B libraries. AMPX can be used to generate a variety of MG libraries that can be used with modern transport codes to perform nuclear analyses. CE or point cross section libraries can be produced for use in Monte Carlo codes and other applications. In addition, AMPX has an internal MG format that can be read by various AMPX modules and codes outside the system. For example, the Standardized Computer Analyses for Licensing Evaluations (SCALE) system has the capability to read AMPX formatted cross section libraries. This manual provides procedures for producing CE and MG neutron cross section libraries.
