## KENO Postprocessor Analysis and Plotting Capabilities

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

**S. M. Bowman**
**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

_**K**_eno_** M**_odule for _**A**_ctivity-_**R**_eaction Rate _**T**_abulation
- 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

## Spent Fuel Storage Array: Fission Activity

## 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**_ _**P**_lots _**E**_specially _**N**_ice _**O**_utput
- 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

- 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**
