CRAD, Assessment Criteria and Guidelines for Determining the Adequacy of Software Used in the Safety Analysis and Design of Defense Nuclear Facilities

Performance Objective:

These guidelines and criteria provide a consistent overall framework for assessment of the processes that are currently in place to ensure that the software being used in the safety analysis and design of the SSCs in defense nuclear facilities is adequate. These reviews will be conducted only on software that is
currently in use, not on software that was previously used as part of a safety analysis and design process.


  • Custom software developed by DOE, its contractors, or subcontractors for use with SS or SC SSCs,
  • Commercial off-the-shelf (COTS) software,
  • Calculation software, such as spreadsheets and math programs (along with their associated user files), used to perform safety analysis and design calculations, and 
  • Database programs and associated user files used to maintain control of information that has nuclear safety implications.
