11.1. AMPX Library Utility Modules

D. Wiarda, A. Holcomb, L. M. Petrie

Abstract

The purpose of this section is to document selected AMPX modules that can benefit the analyst interested in editing, converting, or combining cross-section libraries normally used by the SCALE system modules. The input description for these codes is provided in the documentation of the AMPX nuclear data processing code system that is distributed with SCALE package.

11.1.1. Introduction

AMPX is a modular system [UTILS-WWCD15] that generates continuous energy (CE) and multigroup (MG) cross section data from evaluated nuclear data files such as ENDF/B. All the nuclear data libraries distributed with SCALE have been processed using AMPX. In addition to data processing modules, AMPX also includes a number of useful utility modules for checking, manipulating, and editing the libraries in SCALE. This section lists and briefly describes some of the AMPX utility codes that may be useful to SCALE users. Input instructions for these codes can be found the AMPX code documentation, which is distributed with the SCALE code package. Additional AMPX modules of interest may also found in the documentation.

11.1.2. AJAX: MODULE TO MERGE, COLLECT, ASSEMBLE, REORDER, JOIN, AND/OR COPY SELECTED DATA FROM AMPX MASTER LIBRARIES

AJAX (Automatic Joining of AMPX X-Sections) is a module to combine data from different AMPX libraries. Options are provided to allow merging from any number of files.

11.1.3. ALPO: MODULE TO CONVERT AMPX LIBRARIES INTO ANISN FORMAT

ALPO (ANISN LIBRARY PRODUCTION OPTION) is a module for converting AMPX working libraries into the library format used by the legacy discrete ordinates transport codes ANISN and DORT/TORT contained in the DOORS package cite:rhoades_doors_1998.

11.1.4. CADILLAC: MODULE TO MERGE MULTIPLE COVARIANCE DATA FILES

CADILLAC (Combine All Data Identifiers Listed in Logical AMPX Coverx-format) is a module that can be used to combine multiple covariance data files in COVERX format into a single covariance data file. The material IDs can be changed as needed by the user.

11.1.5. COGNAC: MODULE TO CONVERT COVARIANCE DATA FILES IN COVERX FORMAT

COGNAC (Conversion Operations for Group-dependent Nuclides in AMPX Coverx-format) is a module that can be used to convert a single COVERX-formatted data file from bcd format to binary. Also, COGNAC can be used to convert from binary to bcd, binary to binary, and bcd to bcd.

11.1.6. LAVA: MODULE TO MAKE AN AMPX WORKING LIBRARY FROM AN ANISN LIBRARY

LAVA (Let ANISN Visit AMPX) is a module that can convert an ANISN formatted library (neutron, gamma, or coupled neutron-gamma) to an AMPX working library that can be used in XSDRNPM.

11.1.7. MALOCS: MODULE TO COLLAPSE AMPX MASTER CROSS-SECTION LIBRARIES

MALOCS (Miniature AMPX Library Of Cross Sections) is a module to collapse AMPX master cross-section libraries. The module can be used to collapse neutron, gamma-ray, or coupled neutron-gamma master libraries.

11.1.8. PALEALE: MODULE TO LIST INFORMATION FROM AMPX LIBRARIES

PALEALE lists selected data by nuclide, reaction, data-type from AMPX master and working libraries.

11.1.9. RADE: MODULE TO CHECK AMPX CROSS-SECTION LIBRARIES

RADE (Rancid AMPX Data Exposer) is provided to check AMPX- and ANISN-formatted multigroup libraries. It will check neutron, gamma, or coupled neutron-gamma libraries.

11.1.10. TOC: MODULE TO PRINT AN AMPX LIBRARY TABLE OF CONTENTS

Program TOC is a utility program to print a sorted table of contents of an AMPX cross section library. It is designed to be run interactively, with the cross section library specified as the argument.
