d with sufficient margin, the calculated pressure and temperature conditions resulting from any loss-of-coolant accident. Using the above GDC as its basis, the following top-level attributes should be verified by ITAAC: A. pressure boundary integrity (GDC 14, 16 and 50) B. normal loads (GDC 2) C. seismic loads (GDC 2) D. suppression pool hydrodynamic loads (GDC 4) E. flood, wind, and tornado (GDC 2) F. rain and snow (GDC 2) G. pipe rupture (GDC 4) H. codes and standards (GDC 1) I. 10 CFR 50, Appendix J (GDC 16) In addition, to ensure that the final as-built plant conforms to the certified design, applicants should provide ITAAC to reconcile the as-built plant with the structural design basis. A summary of the top-level structural design requirements for the major structural systems that are verified by the structures and systems in Tier 1 and the piping design information in Tier 1. 4. Pressure Boundary Integrity. To ensure that the applicable requirements of GDC 14, 16, and 50 have been adequately addressed, ITAAC should be established to verify the pressure boundary integrity of the RPV, piping, and primary containment (For PWRs, RV, piping, and primary containment) for the standard design. GDC 16, GDC 50, and 10 CFR 50, Appendix J apply to the primary containment and GDC 14 applies to the RPV (RV for PWRs) and the reactor coolant pressure boundary piping systems. The pressure integrity for these major structural systems are needed to ensure the defense- in-depth principle. 14.3.2-6 March 2007 For the RPV and piping, hydrostatic tests performed in conjunction with the ASME Boiler and Pressure Vessel Code, Section III, should be required by ITAAC. See the standard ITAAC for hydrostatic tests in Appendix D to SRP Section 14.3. For the primary containment, a structural integrity test and containment integrated leakage rate test should be required by ITAAC to be performed on the pressure boundary components of the primary containment in accordance with the ASME Boiler
