CFR Title: 

Content:
the test environment and processes should address the V&V test phase vulnerabilities identified in the vulnerability assessment. The NRC staff may review and audit any of the documentation and/or V&V security analysis and testing to conclude that the digital safety system was developed in a secure environment and that it will be protected from inadvertent actions in its operational environment. In addition Regulatory Guide 1.152 contains guidance on the establishment of SDOEs for digital safety systems to meet criteria of IEEE Std. 603-1991 and 10 CFR 50, Appendix B. d. Test Evaluation Test evaluation includes confirming the technical adequacy of test materials such as plans, designs, and results. These materials should be evaluated for consistency with Criterion II, in its requirement for controlled conditions, and with Criterion XI, in its requirement for the evaluation of test results. e. Evaluation of User Documentation User documentation is important to the safe operation and proper maintenance of safety system software. The requirements of Criterion III for correctly translating the design basis of safety system software into specifications, procedures, drawings, and instructions apply to software documentation, including user documentation. 8. Annexes There are eight informative annexes in IEEE Std. 1012-2004, while IEEE Std. 1028-2008 contains two informative annexes. These annexes are listed here as sources of information; they have not received regulatory endorsement unless otherwise noted: DG-1267, Page 10 IEEE Std. 1012-2004: • Annex A, “Mapping of IEEE Std. 1012 V&V Activities and Tasks,” provides the mappings of IEEE Std. 1012-2004 V&V activities to V&V requirements of the International Organization for Standardization/International Electrotechnical Commission (ISO/IEC) 12207:1995, “Information Technology-Software Life Cycle Processes” (Ref. 16); IEEE Std. 1074-1997, “IEEE Standard for Developing Software Life Cycle Processes”; and
