regulations as they apply to the application being reviewed. The scope of review includes those I&C systems that are identified as substantially identical to systems that have been previously reviewed and approved by the staff. The evaluation of these systems in subsequent sections of Chapter 7 may be based upon prior Staff approval. If any aspect of a design is not identical to that which is referenced, an evaluation must be made to address the adequacy of the different design. Conclusions drawn from this review must be included in the safety evaluation report. Figure 7.0-2 illustrates the life cycle for any I&C system, and relates the application types described below to the life-cycle activities that should be addressed by 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 implementation may focus on component and system requirements, design outputs, and validation (e.g., type testing). Review of computer-based systems should focus on confirming the acceptability and correct implementation of the life-cycle activities. Section 7.1 discusses the review of the overall I&C system concept and generic system requirements. Appendices 7.1-A, 7.1-B, and 7.1-C discuss the review procedures for each acceptance criterion relevant to I&C systems. 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, Appendix 7.0-A describes a generic process for reviewing the unique aspects of computer-based systems, including hardware/software integration. The appendices to Sections 7.0 and 7.1 are to be used in conjunction with Sections 7.1 through 7.9. The HICB review of each life-cycle activity should address the review points covered in
