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

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)

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
