SYSTEM PIPE RUPTURES REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of containment integrity Secondary - None I. AREAS OF REVIEW The mass and energy release analysis for secondary system pipe ruptures is reviewed to ensure the acceptability of the data used to evaluate the containment and subcompartment functional design. The specific areas of review are as follows: 1. Sources of Energy: All of the energy sources from steam and feedwater line break accidents that are available for release to the containment are reviewed. 2. Mass and Energy Release Rate: The mass and energy release rate calculations are reviewed. 6.2.1.4-2 Revision 2 - March 2007 3. Single-Failure Analyses: The single-failure analyses performed for steam and feedwater line isolation provisions that would limit the flow of steam or feedwater to the assumed pipe rupture are reviewed. 4. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) reviews, the staff reviews the applicant's proposed ITAAC associated with the structures, systems, and components (SSCs) related to this SRP section in accordance with SRP Section 14.3, "Inspections, Tests, Analyses, and Acceptance Criteria." The staff recognizes that the review of ITAAC cannot be completed until after the rest of this portion of the application has been reviewed against acceptance criteria contained in this SRP section. Furthermore, the staff reviews the ITAAC to ensure that all SSCs in this area of review are identified and addressed as appropriate in accordance with SRP Section 14.3. 5. COL Action Items and Certification Requirements and Restrictions. For a DC application, the review will also address COL action items and requirements and restrictions (e.g., 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
