that should be addressed in the application. The review of any application should involve all the applicable life-cycle activities. Reviews should confirm the acceptability of system requirements and the adequacy with which the final system meets these requirements. Review of non-digital I&C equipment may focus on component and system requirements, design outputs, and validation (e.g., type testing). In addition to these three aspects, review of digital computer-based systems should also focus on confirming the acceptability of life-cycle activities. SRP Section 7.1 discusses the review of the overall I&C system concept and generic system requirements. SRP Appendices 7.1-A, 7.1-B, 7.1-C, and 7.1-D discuss the review procedures for each acceptance criterion relevant to I&C systems. SRP Sections 7.2 through 7.9 describes the review of system-specific requirements, system design, and implementation. For computer-based systems or components with embedded computers, SRP Appendix 7.0-A describes a generic process for reviewing the unique aspects of computer-based systems, including hardware/software integration. The appendices to SRP Sections 7.0 and 7.1 are to be used in conjunction with SRP Sections 7.1 through 7.9. The review of each life-cycle activity should address the review points covered in Subsections III.A and III.B below. The staff's review emphasis should be commensurate with the safety significance of a given system or aspect of a system's design under review. Probabilistic risk assessments (PRAs), such as those conducted under the Individual Plant Evaluation Program or required as part of applications under 10 CFR Part 52, provide 7.0-6 Revision 7 – August 2016 information that may prove helpful in determining the appropriate level of review. RG 1.174, “An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Licensing Basis,” provides specific guidance on the review of license amendment
