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. The organization responsible for mechanical engineering Review of the stress analyses of the piping that are considered for LBB in accordance with the requirements of Section III of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (Code) is performed under SRP Section 3.9.3. 3.6.3-3 Revision 1 - March 2007 2. The organization responsible for balance of plant Review of the capability, reliability and sensitivity of the reactor coolant pressure boundary leakage detection systems inside the containment in accordance with Regulatory Guide (RG) 1.45 is performed under SRP Section 5.2.5. The specific acceptance criteria and review procedures are contained in the reference SRP sections II. ACCEPTANCE CRITERIA Requirements Acceptance criteria are based on meeting the relevant requirements of the following Commission regulations: 1. GDC 4 as it relates to the exclusion of dynamic effects of the pipe ruptures that are postulated in SRP Section 3.6.2. The design basis for the piping means those conditions specified in the SAR, as amended, and which may include regulations in 10 CFR Part 50, applicable sections of the SRP, Regulatory Guides, and industry standards such as the ASME Code. 2. LBB should only be applied to high energy, ASME Code Class 1 or 2 piping or the equivalent. Applications to other high energy piping will be considered based on an evaluation of the proposed design and inservice inspection requirements as compared to ASME Code Class 1 and 2 requirements. 3. Approval of the elimination of dynamic effects from postulated pipe ruptures is obtained individually for particular piping systems at specific
