Content:
on responsible for SRP Section 15.0.3 must be notified if the containment depressurization time does not meet the acceptance criterion. The primary review organization for this SRP section reviews the assumptions made in the analyses to maximize the calculated containment pressure and temperature. The primary review organization for this SRP section determines the conservatism of the respective containment response analyses by comparing the analytical models, and the assumptions made, with the acceptance criteria in Subsection II of this SRP section and by performing appropriate confirmatory analyses. It is not necessary to perform accident pressure calculations for every plant. The primary review organization for this SRP section will ascertain, however, whether the adequacy of the applicant's calculational model has been demonstrated. The primary review organization for this SRP section determines whether the applicant has identified the pipe break(s) resulting in the highest containment pressure and temperature. Hot leg, cold leg (pump suction), and cold leg (pump discharge) pipe breaks of the reactor coolant system, and secondary system steam and feedwater line breaks, should be analyzed by the applicant. The primary review organization for this SRP section reviews the assumptions used to determine whether the analyses are acceptably conservative. Design Certification applicants should meet the CP containment design pressure margin criterion of Item 1 of the SRP Acceptance Criteria (above). 3. The primary review organization verifies that the containment is designed to withstand hydrogen burning during an accident that releases hydrogen from a 100% fuel clad metal-water reaction as described in Item 10 of the SRP Acceptance Criteria (above). 4. The primary review organization performs confirmatory containment response analyses when necessary. The purpose of these analyses is to confirm the applicant's predictions of the response of the containment to
