OrigenArp -Graphical User Interface

The new OrigenArp graphical user interface (GUI) is a Windows-based program that provides an easy-to-use method for setting up and executing the ORIGEN-ARP spent fuel characterization module in SCALE. ORIGEN-ARP is a sequence that serves as a faster alternative to the SAS2H sequence of the SCALE system to perform point-irradiation calculations with the ORIGEN-S code using problem-dependent cross sections. ARP (Automatic Rapid Processing) uses an algorithm that allows the generation of cross-section libraries for the ORIGEN-S code by interpolation over pre-generated SAS2H cross-section libraries. Interpolations are performed on burnup, enrichment, and optionally, water density. The OrigenArp for Windows GUI provides menus, toolbars, forms, and online help that assist the user in preparing a SCALE input file to execute ARP and ORIGEN-S. This GUI contains several new features, including a simplified input form, referred to as Origen Express, that requires as few as seven key input parameters. It also provides the capability to easily plot ORIGEN-S calculated results via the PlotOPUS interactive Windows plotting program. A sample Origen Express input form and a plot from PlotOPUS are shown in the figures on this page.
