          NRC Library  Document Collections  NUREG-Series Publications  Publications Prepared by NRC ContractorsOPUS/PlotOPUS: An ORIGEN-S Post-Processing Utility and Plotting Program for SCALE (NUREG/CR-6718)

On this page: Publication Information AbstractDownload complete document NUREG/CR-6718 (PDF 18.85 MB)Publication Information **Manuscript Completed:** March 2001**Date Published:** April 2001 **Prepared by:** I. C. Gauld, D. L. Barnett, 0. W. Hermann, S. M. Bowman Oak Ridge National Laboratory Managed by UT-Battelle, LLC Oak Ridge, TN 37831-6370 C. J. Withee, NRC Project Manager **Prepared for:** Spent Fuel Project Office Office of Nuclear Material Safety and Safeguards U.S. Nuclear Regulatory Commission****Washington, DC 20555-0001 NRC Job Code B-0009 Availability Notice Abstract The OPUS utility program produces an output file that can be used for making a variety of plots from output produced by the ORIGEN-S code that computes reactor fuel depletion, activation and fission- product buildup, and the corresponding photon and neutron source spectra. Tables containing individual and total nuclide or element concentrations, in 14 different units, may be generated as a function of time. Three classes of plot data may be produced by OPUS: (1) dominant or selected isotopes or elements, (2) photon and neutron source spectra, and (3) comparisons of selected quantities (totals or individual nuclides) between different ORIGEN-S cases. The input is designed for ease of use with self-explanatory parameter names, free-form input, and commonly used default values. The formatted output data produced by OPUS is designed to be used directly by the PlotOPUS graphics-plotting program. PlotOPUS is an interactive Visual Basic program designed for Windows 9x, 2000, and NT computers. PlotOPUS reads the formatted output data file produced by OPUS, plots the data, and will generate Windows metafile (WMF), JPEG bitmap (JPG), or Windows bitmap (BMP) files for saving the plot images. Even though it is designed to interface with PlotOPUS, the formatted OPUS output file can be easily read by other graphics packages for data visualization.
