LOSS-OF-COOLANT ACCIDENTS (LOCAs) REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of containment integrity Secondary - None I. AREAS OF REVIEW The analyses of the mass and energy release are reviewed to assure that the data used to evaluate the containment and subcompartment functional design are acceptable for that purpose. The specific areas of review are as follows: 1. The energy sources that are available for release to the containment. 2. The mass and energy release rate calculations for the initial blowdown phase of the accident. 3. For pressurized water reactor (PWR) plants, because of the additional steam generator stored energy available for release, the mass and energy release rate calculations for the core reflood and post-reflood phases of the accident. 6.2.1.3-2 Revision 3 - March 2007 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 the referenced DC. Additionally, a COL applicant must
