This interim staff guidance (ISG) provides the staff’s position on what an acceptable analysis using CMS should include, and what information should be reviewed by the staff when considering a submittal from an applicant using CMS in the design review of a storage cask or transportation package. This ISG applies to both thermal and structural analyses utilizing CMS. However, application of this ISG does not extend to shielding and criticality analyses that rely on CMS since present guidance sufficiently addresses current issues in these areas.
