posed application. 7.0-5 Revision 6 - May 2010 Figure 7.0-3 illustrates the life-cycle activities for any I&C system and relates the application types described below (in Subsections III.A, III.B, and III.C) to the life-cycle activities 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, computer-based system (e.g., programmable logic controllers) implementation may focus on component and system requirements, design outputs, and validation (e.g., type testing). Review of digital computer-based systems should focus on confirming the acceptability and correct implementation 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 describe 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, "Early Site Permits; Standard Design Certifications;
