that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the following type to be included in the staff’s safety evaluation report. The reviewer also states the bases for those conclusions. 1. The NRC staff concludes that the designs of the information systems important to safety are acceptable and meet the relevant requirements of General Design Criteria (GDC) 1, 2, 4, 13, 19, and 24, and 10 CFR 50.34(f), 10 CFR 50.55a(a)(1), and 10 CFR 50.55a(h). The staff conducted a review of the information systems important to safety for conformance to the guidelines in the regulatory guides and industry codes and standards applicable to these systems. The staff concludes that the applicant/licensee adequately 7.5-11 Revision 5 - March 2007 classified and identified the guidelines applicable to these systems. Based on the review of the system design for conformance to the guidelines, the staff finds that the systems conform to the guidelines applicable to these systems. Therefore, the staff finds that the applicable requirements of GDC 1 and 10 CFR 50.55a(a)(1) have been met. The review included the identification of those systems and components for the information systems important to safety that are designed to survive the effects of earthquakes, other natural phenomena, abnormal environments, and missiles. Based on the review, the staff concludes that the applicant/licensee has identified those systems and components consistent with the design bases for those systems. Sections 3.10 and 3.11 of the SER address the qualification programs to demonstrate the capability of these systems and components to survive these events. Therefore, the staff finds that the identification of these systems and components satisfies the applicable requirements of GDC 2 and 4. The non-safety portions of information systems important to safety are appropriately isolated from safety systems, including the safety portions
