Content:
andards, specifications, and regulatory guides (RGs), and other industry standards that are used in the design, fabrication, construction, testing, and inservice surveillance of the steel containment. The specific editions, dates, or addenda identified for each document are reviewed. 3. Loads and Loading Combinations. The information pertaining to the applicable design loads and various load combinations, with emphasis on the extent of compliance with ASME Code, Section III, Division 1, Subsection NE; RG 1.57; and Subsection II.3 of this SRP section are reviewed. The loads normally applicable to steel containments include the following: A. Those loads encountered during preoperational testing. B. Those loads encountered during normal plant startup, operation, and shutdown, including dead loads, live loads, thermal loads resulting from operating temperatures, and hydrostatic loads such as those present in pressure-suppression containments using water. 3.8.2-4 Revision 3 - May 2010 C. Those loads to be sustained during severe environmental conditions, including those induced by design wind (if not protected by a shield building) and the operating-basis earthquake (OBE). D. Those loads to be sustained during extreme environmental conditions, including those induced by the design-basis tornado (if not protected by a shield building) and the safe-shutdown earthquake (SSE) specified for the plant site. E. Those loads to be sustained during abnormal plant conditions, which include loss-of-coolant accidents (LOCAs). The main abnormal plant condition for containment design is the design-basis LOCA. The staff will also consider other accidents involving various high-energy pipe ruptures. Loads induced on the containment by such accidents include elevated temperatures and pressures and possibly localized loads such as jet impingement and associated missile impact. Also included are external pressure loads generated by events inside or outside the containment. F. Those loads to
