SQA Directives and Guidance


  • DOE O 414.1D, Quality Assurance
  • DOE G 414.1-4, Software Guide for use with 10 CFR 830 Subpart A, Quality Assurance Requirements, and DOE O 414.1C, Quality Assurance

DOE Order O 414.1D, Quality Assurance, includes Attachment 4 addressing SQA requirements for nuclear safety applications at DOE nuclear facilities. The DOE O 414.1D was issued April 25, 2011. This Order and its associated Guide for safety software, DOE G 414.1-4, Safety Software Guide for use with 10 CFR 830 Subpart A, Quality Assurance Requirements.

The Order identifies 10 software quality work activities that are to be performed using the graded approach specified in the Order. These 10 work activities are: (1) software project management, (2) software risk management, (3) software configuration management, (4) procurement and vendor management, (5) software requirements identification and management, (6) software design and implementation, (7) software safety design, (8) verification and validation, (9) problem reporting and corrective action, and (10) training of personnel in the design, development, use and evaluation of safety software. These 10 work activities were consolidated from practices and activities identified in several well known consensus standards and federal requirements. Safety software must be acquired, developed and implemented using ASME NQA-1-2008 with the NQA-1a-2009 addenda (or later edition), Quality Assurance Requirements for Nuclear Facility Applications, Part 1 and Subpart 2.7, or other national or international consensus standards that provide an equivalent level of quailty assurance requirements as NQA-1-2008.

DOE Guide G 414.1-4 provides acceptable implementation strategies and appropriate standards for the 10 software quality work activities. This Guide incorporates practices from appropriate existing national/international standards and processes currently in use at DOE facilities. The Guide describes how the quality work activities may be implemented using a graded approach to satisfy the Order requirements. The grading guidance identifies subactivities that can be implemented at varying levels of rigor to align with the grading level (Level A, B or C) for the specific safety software application. The grading level is based upon the impact on safety and the safety software type (e.g., custom developed, configurable, or acquired).

The Guide contains two key appendices: Appendix B, Procedure for Adding or Revising Software to, or Deleting from the DOE Safety Software Central Registry and Appendix F, DOE O 414.1C Criteria Review and Approach Document. These appendices to reflect the 10 work activities in the Order. The assessment/evaluation criteria and information collected during evaluations of proposed Central Registry codes or during assessments of safety software are based upon the 10 work activities and their sub-activities in the Guide.
