LOSS-OF-COOLANT ACCIDENTS (LOCAs) REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of containment systems | 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 review includes the following areas: 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. Rev. 2 - January 2006 6.2.1.3-2 4. Inspection, Test, Analysis, and Acceptance Criteria (ITAAC) | | For design certification and combined license reviews, the applicant's proposed | information on the ITAAC associated with the systems, structures, and components | (SSCs) related to this SRP section is reviewed in accordance with SRP Section 14.3. It | is recognized that the review of ITAAC is performed after review of the application | against acceptance criteria contained in this SRP section. Furthermore, the ITAAC are | reviewed to assure that all SSCs in this area of review are identified and addressed as | appropriate in accordance with SRP 14.3. | Review Interfaces The related SRP section is identified by functional relationship. Review of the acceptability of piping design criteria, selected break locations and break sizes based on the provisions made to limit pipe motion, for breaks postulated to occur within subcompartments is performed under SRP Section 3.6.2. The acceptance criteria and review procedures are contained in the referenced SRP section. II. ACCEPTANCE CRITERIA The acceptance criteria given below apply to the mass and energy release analysis for | postulated
