nto NRC regulations nor endorsed in a regulatory guide, licensees and applicants may consider and use the information in the referenced standard, if appropriately justified and consistent with current regulatory practice. Harmonization with International Standards This regulatory guide endorses, in whole or in part, international consensus standards and reports produced by international organizations such as the Institute of Electrical and Electronic Engineers (IEEE). The IEEE is a non-profit professional association dedicated to advancing technological innovation and excellence. It has more than 400,000 members in more than 160 countries and produces 30% of the world's literature in the electrical and electronics engineering and computer science fields including multiple tutorials and standards produced by its standardization committees. Endorsement, in whole or in part, of international standards reduces the need for the development of unique NRC standards and is consistent with the agency goal of improved harmonization with international organizations. DG-1267, Page 6 C. STAFF REGULATORY GUIDANCE This regulatory guide applies to all aspects of the software life cycle within the system life-cycle context. IEEE Std. 1012-2004 provides an acceptable approach to the NRC for meeting the agency’s regulatory requirements on the V&V of safety system software with the exceptions and additions listed in these regulatory positions. In this section of the guide, the cited criterion refers to Appendix B to 10 CFR Part 50 unless otherwise noted. The methods in IEEE Std. 1028-2008 provide an approach acceptable to the NRC staff for carrying out software reviews, inspections, walkthroughs, and audits, subject to the exceptions and additions listed in these regulatory positions. These methods are often used in association with software quality assurance activities. The annexes to IEEE Std. 1012-2004 and IEEE Std. 1028-2008 contain information that may be useful. However, the
