ing to Evolutionary and Advanced Light-Water Reactor (ALWR) Designs”), the reviewer should determine that the design, including DCSs, has sufficient D3. See SRP BTP 7-19 for guidance on reviewing D3 analyses. • DCSs exposed to seismic hazard - The reviewer should determine whether the subject DCS equipment is located in seismic Category I structures. In certain designs, some connected data communication or multiplexer equipment may be located in non-seismic Category I structures. For these cases, the reviewer must ensure that simultaneous seismic destruction or perturbation of the exposed equipment does not simultaneously render redundant DCSs ineffective. 7.9-9 Draft Revision 6 - August 2015 For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the final safety analysis report (FSAR) meets the acceptance criteria. DCs have referred to the FSAR as the design control document. The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL action items; however, to ensure these COL action items are addressed during a COL application, they should be added to the DC FSAR. For review of a COL application, the scope of the review is dependent on whether the COL applicant references a DC, an early site permit or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). For review of both DC and COL applications, SRP Section 14.3 should be followed for the review of ITAAC. The review of ITAAC cannot be completed until after the completion of this section. IV. EVALUATION FINDINGS The reviewer verifies 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
