The SCALE Criticality Safety Analysis sequences: Status and Future Directions
- Oak Ridge National Laboratory (ORNL), Oak Ridge, TN (United States)
The Standardized Computer Analyses for Licensing Evaluation (SCALE) code system was originally conceived and developed in the late 1970s for the US Nuclear Regulatory Commission. The goal was to provide easy-to-use, yet accurate, analysis capabilities for evaluating the criticality safety, shielding, and heat transfer aspects of transportation packages for radioactive material. The Criticality Safety Analysis Sequences (CSAS) for SCALE were developed to "automate" problem-dependent cross-section and material processing prior to execution of the well-established XSDRNPM or KENO codes for the calculation of keff. The criticality analysis sequences provided in SCALE-4 are summarized in Table 1. The SCALE system continues to be maintained and enhanced by staff of the Computing Applications Division at Oak Ridge National Laboratory (ORNL). The purpose of this paper is to discuss recent efforts to improve system portability and user interfaces and to provide information on going work to enhance the analysis capabilities.
