available for release from the various sources with the acceptance criteria listed in Section II, above. The reviewer determines the acceptability of the analytical models and the assumptions used to calculate the rates of mass and energy release during the initial blowdown, core reflood, and post-reflood phases of a LOCA. The reviewer also compares energy inventories at various times during a LOCA to ensure that the energy from the various sources has been accounted for and has been transferred to the containment on an appropriate time scale. The reviewer reviews comparisons made by the applicant to experimental data and makes comparisons to other available experimental data to determine the amount of conservatism in the mass and energy release models. The reviewer may perform confirmatory analyses of the mass and energy profiles. The purpose of the analysis is to confirm the predictions of the mass and energy release rates appearing in the safety analysis report, and to confirm that an appropriate break location has been considered in these analyses. For reviews under 10 CFR Part 52, the reviewer should follow the above procedures to verify | that the design set forth in the safety analysis report, and as applicable, site interface | requirements, and combined license action items, meet the acceptance criteria. Following this | review, SRP Section 14.3 should be followed for the review of Tier I information for the design, | including the site parameters, interface criteria, and ITAAC. | IV. EVALUATION FINDINGS The conclusions reached on completion of the review of this SRP section are presented in SRP Section 6.2.1. V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plan for using this SRP section. This SRP section will be used by the staff when performing safety evaluations of design | certifications and license applications submitted by applicants pursuant to 10 CFR 50 or 10 CFR | 52.
