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. Evaluation findings applicable to any DCS: The NRC staff conducted a review of these systems for conformance to the guidelines in the RGs and industry codes and standards applicable to these systems. The staff concluded that the applicant or licensee adequately identified the guidelines applicable to these systems. Based on the review of the system design for conformance to the guidelines, the staff finds that there is reasonable assurance that the systems fully conform to the guidelines applicable to these systems. Therefore, the staff finds that the requirements of GDC 1 and 10 CFR 50.54(jj) and 10 CFR 50.55(i) have been met. Additional evaluation findings applicable to all DCSs that support safety functions: The NRC staff concludes that the design of the DCS meets the relevant requirements of 10 CFR 50.55a(h). The review included the identification of those systems and components for the DCS 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 or 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 requirements of General Design Criteria 2 and 4. Additional evaluation findings applicable to all DCSs that support protection system functions (RTS, SRP Section 7.2, or ESFAS, SRP Section 7.3): 7.9-10 Draft Revision 6 - August 2015 Based on the review of system functions, the staff concludes that the
