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. BowmanOak 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

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 plot of 235U and 238U fission activities

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
