CSAS/KENO V.a Criticality Safety Analysis Sequence

CSAS is the control module designed for executing all the criticality analysis sequences except those using KENO-VI. The analytic sequence designated by =CSAS25 follows the execution path BONAMI, NITAWL, and KENO V.a. The sequence =CSAS4 follows the same execution path, but repeats the BONAMI, NITAWL, and KENO V.a. analysis as part of a search for the geometry dimension or material concentration that provides the minimum, maximum, or specified keff value. The above sequences are modified to include cell-weighting with XSDRNPM if =CSAS2X or =CSAS4X is specified by the input. Other sequences are available to obtain keff via a one-dimensional XSDRNPM model or to simply prepare problem-dependent cross-sections for subsequent use in analyses with individual codes. If PARM=CENTRM is specified on the =CSASnn line, CENTRM/PMC replaces NITAWL in the above sequences. A windows GUI named GeeWiz is available for preparing and executing input files. KMART can be executed following the CSAS/KENO V.a sequence to obtain reaction rates, while possibly collapsing the data to a fewer group structure. These reaction rates and fluxes can then be plotted using the Javapeno GUI. Also the reaction rates can be plotted in a three-dimensional perspective plot using KENO3D.
