olve Staff concerns. This helps assure that changes are correctly propagated through the design effort, thus improving the Staff's confidence in design quality. Structure of SRP Chapter 7 Figure 7.0-2 illustrates the structure of SRP Chapter 7. SRP Section 7.0 should be the entry point for any I&C review activity. It discusses the different types of applications I&C reviewers may encounter, the information expected to accompany each application, the general scope of the I&C review, and the expected interfaces with other elements of a plant review. SRP Section 7.0 also encourages the reviewer to develop a review plan to guide review activities and to communicate expectations to management and the applicant. Because digital computer-based safety systems are a relatively new issue in nuclear power plants, SRP Appendix 7.0-A is provided to explain the general philosophy and approach to the review of digital computer-based systems. The NRC standard format and content guides, Regulatory Guide (RG) 1.70, "Standard Format and Content of Safety Analysis Reports for Nuclear Power Plants (LWR Edition)," and RG 1.206, "Combined License Applications for Nuclear Power Plants (LWR Edition)," advise the applicant that Section 7.1 of safety analysis reports (SARs) should list all I&C and supporting systems that are important to safety and should identify the regulatory requirements applicable to each of these systems. Consequently, SRP Section 7.1 identifies the acceptance criteria and regulatory guidance expected to apply to these systems. SRP Table 7.1 lists the regulatory requirements, acceptance criteria, and guidance relevant to I&C and summarizes their applicability to each of the typical systems. SRP Appendix 7-1.A discusses the regulatory requirements, acceptance criteria, and guidance in more detail and provides review guidance for each. Three IEEE standards play extensive roles in the review of I&C systems important to safety: (1) IEEE Std. 279-1971, "Criteria for
