The criteria in Appendices A and B apply to systems and related quality assurance processes, and the requirements extend throughout the life cycle of the protection system especially when those systems include software. There are further requirements for software testing which can be found in the documentation retention and handling section of 10 CFR Part 21.51, “Maintenance and Inspection of Records” (Ref. 5).

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. 6). 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. 7) 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.
