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

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

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

![Page 14: KENO Postprocessor Analysis and Plotting Capabilities 2002 ANS Winter Meeting Washington D.C. November 17 - 21, 2002 D. F. Hollenbach, L. M. Petrie, B](https://reader034.vdocuments.mx/reader034/viewer/2022042718/56649ead5503460f94bb454c/html5/thumbnails/14.jpg)
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)

Javapeno is interactive
![Page 18: KENO Postprocessor Analysis and Plotting Capabilities 2002 ANS Winter Meeting Washington D.C. November 17 - 21, 2002 D. F. Hollenbach, L. M. Petrie, B](https://reader034.vdocuments.mx/reader034/viewer/2022042718/56649ead5503460f94bb454c/html5/thumbnails/18.jpg)
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
