SAR. 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. The staff concludes that the design of the RCS high-point vents is acceptable and meets the relevant requirements of 10 CFR Part 50, 10 CFR 50.44(c), 10 CFR 50.46, 10 CFR 50.46a, 10 CFR 50.49, and 10 CFR 50.55a, and GDC 1, 14, 17, 19, 30, 34, and 36 and Appendix B to 10 CFR Part 50. This conclusion is based on the following: The RCS high-point vents include components and piping to remotely relieve noncondensible gases from the primary coolant system and vent the gases to the containment atmosphere or to holdup tanks within containment. [The review has included the applicant's proposed design criteria and design bases, and these meet the requirements for the CP stage.] [The review has included the applicant's analysis of the vent system design with the design criteria and design bases and has included operating procedures for the vents for the OL stage.] In addition, the basis for acceptance in the staff review is conformance of the applicant's designs, design criteria, and design bases for the RCS vents and supporting systems to applicable regulatory guides, branch technical positions, and industry standards [identify each document and describe how the applicant has implemented each]. For DC and COL reviews, the findings will also
