2002 ANS Winter Meeting
Washington D.C.
November 17 - 21, 2002

Oak Ridge National Laboratory
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
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
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

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
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
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 also plots XSDRNPM
results
Javapeno is interactive
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
