Revision 3 - March 2007 (DCD). 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 (ESP) 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 also states the bases for those conclusions. 1. The TGS includes all components and equipment normally provided, such as turbine main steam stop and control valves and reheat steam stop and intercept valves. The scope of review of the TGS for the plant includes layout drawings, P&IDs, and descriptive information for the system and for control and supporting systems that are essential to its operation. 2. The basis for acceptance of the TGS in the NRC review was conformance of the designs, design criteria, and design bases to the Commission’s regulations, as cited in the GDC of Appendix A to 10 CFR Part 50. The staff concludes that the plant design is acceptable and meets the requirements of GDC 4 with respect to the protection of SSCs important to safety from the effects of turbine missiles. The applicant has met this requirement by providing a turbine overspeed protection system to control the turbine action under all operating conditions, which ensures that a full-load turbine trip will not cause
