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

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  Java Plots 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 235 U and 238 U 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
