identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. Section 7.0 provides an overview of the review process for I&C systems. Within this process, the review of Section 7.1 of the SAR should confirm that the I&C systems important to safety are addressed in Chapter 7 of the SAR and that the applicant or licensee commits to appropriate acceptance criteria and guidelines applicable to each of these systems. Thus, the review of SAR Section 7.1 focuses on confirming that commitments made for I&C systems fulfill the requirements of 10 CFR 50.54(jj) and 10 CFR 50.55(i), and 10 CFR Part 50, Appendix A, General Design Criterion 1, “Quality Standards and Records.” These sections require that SSCs important to safety be designed, fabricated, erected and tested to quality standards commensurate with the importance of the safety function to be performed. Therefore, the review of SAR Section 7.1 should confirm that the SAR includes: (1) a discussion regarding the applicability of each criterion and guideline for each system important to safety, and (2) a statement that the criteria 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
