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, multiple international consensus standards 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 multiple 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. C. STAFF REGULATORY GUIDANCE The requirements in ANSI/IEEE Std. 1008-1987 provide an acceptable approach for meeting the NRC’s regulatory requirements on the unit testing 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. This regulatory guide does not endorse the appendices to ANSI/IEEE Std. 1008-1987, except as noted below. 1. Software Testing Documentation Section 1.1 of ANSI/IEEE Std. 1008-1987 mandates the use of the test design specifications and the test summary report documents, which can be found in IEEE Std. 829-2008, Clauses 10, “Level Test Design” and 17, “Master Test Report”, respectively. In addition, ANSI/IEEE Std. 1008-1987 either incorporates additional information into these two documents or indicates the need for additional documentation. Regardless of
