s that are acceptable to the responsible reviewing organization for the subject application. The purpose of the analysis is to confirm the predictions of the mass and energy release rates appearing in the safety analysis report and to verify that 6.2.1.2-7 Revision 3 - March 2007 the analysis considered an appropriate break location and size including LBB considerations. 4. Design Pressure. For a CP PSAR, OL, DC, or COL FSAR, the reviewer ascertains that the subcompartment design procedures include appropriate margins above the calculated values, as given in Subsection II. Using the nodalization of each subcompartment as specified in the safety analysis report, the reviewer performs analyses using one of several available computer programs to determine the adequacy of the calculated peak differential pressure. The computer program used will depend upon the subcompartment under review and the flow regime. 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 (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
