d designs should confirm that the SER open items are acceptably resolved for the proposed application. 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 7.0-5 Revision 5 - March 2007 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
