CFR Part 50 as they apply to the development of SRSs. The criteria of Appendix A and Appendix B to 10 CFR Part 50 apply to systems and related quality standards and quality assurance processes as well as the software elements of those systems. The NRC issues regulatory guides to describe to the public methods that the staff considers acceptable for use in implementing specific parts of the agency’s regulations, to explain techniques that the staff uses in evaluating specific problems or postulated accidents, and to provide guidance to applicants. However regulatory guides are not substitutes for regulations and compliance with them is not required. The information provided by this regulatory guide is also in the Standard Review Plan, NUREG-0800, “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition,” Chapter 7, “Instrumentation and Controls,” (Ref. 5). The NRC staff uses the NRC Standard Review Plan to review 10 CFR Part 50 and 10 CFR Part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants,” (Ref. 6) license applications. This regulatory guide contains information collection requirements covered by 10 CFR Part 50 that the Office of Management and Budget (OMB) 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. A licensee’s compliance with these standards does not
