approved under OMB control number 3150-0011. The NRC may neither conduct nor sponsor, and a person is not required to respond to, an information collection request or requirement unless the requesting document displays a currently valid OMB control number. This regulatory guide is a rule as designated in the Congressional Review Act (5 U.S.C. 801- 808). However, OMB has not found it to be a major rule as designated in the Congressional Review Act. B. DISCUSSION Background The use of industry consensus standards, such as IEEE standards, is part of an overall approach to meeting the requirements of 10 CFR Part 50 when developing safety systems for nuclear power plants. Compliance with these standards does not guarantee that regulatory requirements will be met. However, 1 The term “safety systems” is synonymous with “safety-related systems.” The scope of the GDC includes systems, structures, and components “important to safety.” However, the scope of this regulatory guide is limited to “safety systems,” which are a subset of “systems important to safety.” DG-1206, Page 3 such compliance does ensure that practices accepted within various technical communities will be incorporated into the development and quality assurance processes used to design safety systems. These practices are based on past experience and represent industry consensus on approaches used for the development of such systems. This regulatory guide refers to software incorporated into the instrumentation and control systems covered by Appendix B to 10 CFR Part 50 as “safety system software.” The identification, control, and documentation of safety system software must be accomplished as part of the effort to comply with NRC requirements. In addition to the record maintenance requirement of GDC 1, Appendix B provides detailed quality assurance criteria, including criteria for administrative control, design documentation control, design interface control, design change control,
