[en] The KENO V.a and KENO-VI three-dimensional Monte Carlo criticality computer codes in the SCALE (Standardized Computer Analyses for Licensing Evaluation) computer software system developed at Oak Ridge National Laboratory (ORNL) are widely used and accepted around the world for criticality safety analyses. As part of current development efforts to improve SCALE's ease of use, the SCALE project team at ORNL has developed a new integrated graphical visualization package for KENO V.a and KENO-VI in SCALE 5.1. This package uses the SCALE Graphically Enhanced Editing Wizard (GeeWiz) as the visualization control center that provides users the capability to set up, execute, plot, and view results from KENO in a friendly, colorful, and interactive computing environment without ever using a text editor or a command prompt
