, interface requirements and site parameters). For a COL application referencing a DC, a COL applicant must address COL action items (referred to as COL license information in certain DCs) included in the referenced DC. Additionally, a COL applicant must address requirements and restrictions (e.g., interface requirements and site parameters) included in the referenced DC. Review Interfaces Other SRP sections interface with this section as follows: 1. Review of the various types and aspects of the containment design are identified in SRP Section 6.2.1. 2. The seismic classification and system quality group classification of steam and feedwater line isolation valves are reviewed under SRP Sections 3.2.1 and 3.2.2 to determine the acceptability of these valves in limiting the mass and energy releases from the steam and feedwater systems. 3. Postulated pipe break locations and sizes are reviewed under SRP Section 3.6.2. 4. The time assumed for operator action to close the manual valves in the auxiliary feedwater system is reviewed under SRP Section 10.4.9. The specific acceptance criteria and review procedures are contained in the referenced SRP sections. II. ACCEPTANCE CRITERIA Requirements Acceptance criteria are based on meeting the relevant requirements of the following Commission regulations: 6.2.1.4-3 Revision 2 - March 2007 1. General Design Criteria (GDC) 50, as it relates to providing sufficient conservatism in the mass and energy release analysis for postulated pressurized-water reactor (PWR) secondary system pipe ruptures to ensure the reactor containment structure, including access openings, penetrations, and the containment heat removal system shall be designed so that the containment structure and its internal compartments can accommodate, without exceeding the design leakage rate and with sufficient margin, the calculated pressure and temperature conditions resulting from any loss-of-coolant accident. 2. 10 CFR 52.47(b)(1), which requires that a DC
