simply inherit the controls of the supported system. The reviewer considers the activities, including tests, performed to implement a surveillance requirement and confirms that SSC availability can be adequately determined with the surveillance requirement. Guidance Specific to DC and COL applications For review of a DC application, the reviewer should follow the above procedures to verify that the design set forth in the 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 to address the regulatory criteria stated in the section on RTNSS in the staff’s Safety Evaluation Report (SER) and that the review and calculations (if applicable) support conclusions of the following type to be included in the SER. The reviewer also states the bases for those conclusions. 19.3-13 Draft Rev.0 – June 2013 1. The staff concludes that the applicant’s process for using the focused PRA results to identify RTNSS-important nonsafety-related SSCs follows the process approved by the NRC and is therefore acceptable. 2. Based on its review, the staff concludes that the applicant has correctly identified the nonsafety equipment relied upon to meet the SBO and ATWS rules
