Content:
ding 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. 3.8.1-20 Revision 4 - September 2013 This SRP section 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. This SRP section also describes a deterministic methodology for estimating the ultimate pressure capacity of reinforced concrete and prestressed concrete containments. Meeting these requirements and criteria provide assurance that the containment structure, including the penetrations and the internal compartments, will be able to withstand the loads resulting from pressure and temperature conditions caused by any LOCA and will perform its design safety function. 6. Compliance with Appendix B to 10 CFR Part 50 requires that applicants establish and maintain a quality assurance program for the design, construction, and operation of SSCs. This SRP section provides guidance specifically related to design, construction, testing and inservice surveillance of concrete containments. Subsection II.2 of
