  1. KENO Postprocessor Analysis and Plotting Capabilities 2002 ANS Winter Meeting Washington D.C. November 17 - 21, 2002 D. F. Hollenbach, L. M. Petrie, B. T. Rearden, S. M. Bowman Oak Ridge National Laboratory

  2. Introduction • New and improved postprocessing capabilities for KENO V.a and KENO-VI will be available in SCALE 5 • KMART for KENO V.a • KMART6 for KENO-VI • Results from these codes can be plotted in • KENO3D • Javapeno

  3. KMART / KMART6 • Keno Module for Activity-Reaction Rate Tabulation • Reads a KENO V.a or KENO-VI restart file and working cross-section library • Calculates total or group activities, fluxes, fission densities • Activities specified by nuclide identifier and MT number of corresponding reaction rate • Can collapse multigroup data to fewer groups

  4. KMART / KMART6 • Specified data are printed in SCALE output file • Results also written to an ASCII file that can be read by SCALE visualization and plotting programs • KENO3D • Javapeno

  5. KENO3D • Powerful, state of the art 3-D visualization tool that displays KENO V.a or KENO-VI geometry models • Can read KMART data file and overlay results on the KENO model used to generate the data

  6. Sheba-II Critical Experiment Low enriched uranyl fluoride solution in a stainless steel tank

  7. KENO3D plot of235U fission activity

  11. Spent Fuel Storage Array: Fission Activity

  12. You can do this at home!(or in your office) • What you will need • SCALE 4.4a • KENO3D Version 2.0 • Download latest versions of KMART and KENO3D from the SCALE website (updated version of KENO3D will be posted next week) • Download the updated KMART user manual

  13. Javapeno • JavaPlots Especially Nice Output • Plots data from SCALE 5 modules • SEN1 - Sensitivity sequence • SEN3 - Sensitivity sequence • SMORES - Material optimization sequence • KMART – KENO V.a activities postprocessor • KMART6 - KENO-VI activities postprocessor

  14. Javapeno • Plots the following types of data for each energy group normalized by unit lethargy • Sensitivities • Reaction-rates • Fluxes • Javapeno plots can be printed directly or exported using a variety of graphics formats • Because it uses Java, Javapeno will work on any computer which has an available Java Runtime Environment (e.g., Windows, Unix, Linux, Mac OSX)

  15. Javapeno plot of 235U and 238U fission activities

  16. Javapeno also plots XSDRNPM results

  17. Javapeno is interactive

  18. Conclusions • KMART and KMART6 postprocessors provide activities, fluxes, fission densities from KENO calculations • These results can be easily plotted with the interactive KENO3D or Javapeno tools to present data in a form that is easy to analyze and is suitable for inclusion in reports and presentations
