PRC-NS-00029-VA, Rev. 0<strong>CritView</strong>: <strong>An</strong><strong>Electronic</strong> <strong>Handbook</strong><strong>for</strong> <strong>Criticality</strong> <strong>Safety</strong>Presented to: American <strong>Nuclear</strong>SocietyPresented by: Scott Finfrock
Example ARH-600 FigurePRC-NS-00029-VA, Rev. 03
<strong>CritView</strong> <strong>Electronic</strong> <strong>Handbook</strong>• A <strong>Nuclear</strong> <strong>Criticality</strong> <strong>Safety</strong> Program (NCSP) Project– Purpose:• Preserve ARH-600 data• Improve usability• Provide additional data sets beyond ARH-600• Provide ready means <strong>for</strong> adding additional data setsPRC-NS-00029-VA, Rev. 04
Example <strong>CritView</strong> FigurePRC-NS-00029-VA, Rev. 05
Software Features• Windows Interface• Extensive Library of Peer Reviewed Data• Data Filters• Flexible DisplayPRC-NS-00029-VA, Rev. 06
Data Library• ARH-600 Scans• LA-10860 Scans (currently only a subset available)• MCNP Reproduction of most ARH-600 DataPRC-NS-00029-VA, Rev. 07
Example Figure Showing MCNP DataPRC-NS-00029-VA, Rev. 08
Data Filters• Source (ARH-600, MCNP, etc.)• Material (Plutonium, Uranium, etc.)• Geometry• Reflector ThicknessPRC-NS-00029-VA, Rev. 09
Display Features• Axis Parameters• Axis Dimensions• Plot Type (log or linear)• Plot Scale (zoom in or out)• Curve Features (dashed lines, colors, thickness, etc.)• Legend• Data Display Values• Compare Curves (show difference between curves)• Save Plots as JPEG filesPRC-NS-00029-VA, Rev. 010
Findings• MCNP Results Compared to ARH-600– Generally good agreement– Critical dimensions typically 1% - 2% higher <strong>for</strong> ARH-600– Loss of precision in scanned dataPRC-NS-00029-VA, Rev. 011
