ions of Appendix J to 10 CFR Part 50, as described in SRP Section 6.2.6. SRP Section 3.8.1 provides guidance related to methods, including load combinations, acceptance criteria, standards, and codes, to ensure compliance with GDC 16. Meeting these requirements and criteria provide assurance that an uncontrolled release of radioactivity to the environment will be prevented and that the design conditions of the reactor coolant pressure boundary will be maintained for as long as required. 5. Compliance with GDC 50 requires that the reactor containment structure, including access openings, penetrations, and containment heat removal systems, be designed so that the structure and its internal compartments will have the capability to accommodate, without exceeding the design leakage rate and with sufficient margin, the calculated pressure and temperature conditions resulting from any LOCA. The calculated margin should reflect consideration of (1) the effects of potential energy sources which have not been included in the determination of the peak conditions (such as energy in steam generators) and, as required by 10 CFR 50.44, the energy from metal-water and other chemical reactions that may result from degradation but not total failure of emergency core cooling functioning; (2) the limited experience and experimental data available for defining accident phenomena and containment responses; and (3) the conservatism of the calculational model and input parameters. SRP Section 3.8.1 provides guidance for methods, including load combinations, acceptance criteria, standards, and codes to ensure that the design of the containment can withstand the pressure loads and temperature conditions resulting from any LOCA. SRP Section 3.8.1 also describes a deterministic methodology for estimating the ultimate pressure capacity of reinforced concrete and prestressed concrete containments and also provides guidance for reviewing alternate methodologies. Meeting these requirements and
