and guidelines are implemented or will be implemented in the design of I&C systems important to safety. If exceptions to the guidelines are taken, the review confirms that an acceptable basis has been provided for those exceptions. The reviewer is expected to develop an understanding of the fundamental I&C system architecture as well as the functional allocation to the various I&C systems and to develop a tabulation of the I&C systems important to safety and the acceptance criteria and guidelines applicable to these systems. The reviewer should also identify the elements of I&C systems important to safety that are identical to those previously reviewed by the staff and the portions of the staff's review that may be based on prior NRC approval. The bases for prior approval include the staff’s evaluation of applications for construction permits and operating licenses, preliminary and final design approvals for standardized plants, and topical reports. The review of Section 7.1 of the SAR is performed as follows: 1. Section 7.1 is reviewed to confirm that all I&C systems important to safety are included in Chapter 7. Normally, Chapter 7 of the SAR should address each of the I&C systems included in the areas of review for SRP Section 7.1. This review should confirm that all I&C systems, including embedded computers and software necessary to support the operation of safety systems, are identified in SAR Section 7.1 and discussed in subsequent sections of SAR Chapter 7. The safety systems supported by the I&C system are described in other sections of the SAR (particularly in Chapters 5, 6, 8, 9, 10, 15, and 18). The review of the systems identified is coordinated (as described in SRP Section 7.0) with the organizations that have primary review responsibility for the supported systems. 2. The regulatory requirements applicable to each of the I&C systems important to safety are reviewed to confirm that the applicant has appropriately identified requirements applicable to
