dance provided byRG 1.136 (see Subsection II.3 of this SRP section). The loads normally applicable to concrete containments include the following: A. Those loads encountered during construction of the containment, including dead loads, live loads, prestress loads, temperature, wind, earth pressure, snow, rain, and ice, and construction loads that may be applicable such as material loads, personnel and equipment loads, horizontal and vertical construction loads, loads that are induced by the construction sequence and by the differential settlements of the soil under and to the sides of the containment building, erection and fitting forces, equipment reactions, and form pressure. B. Those loads encountered during preoperational testing. C. Those loads encountered during normal plant startup, operation, and shutdown, including dead loads, live loads, thermal loads resulting from operating temperatures, hydrostatic loads, and hydrodynamic loads resulting from safety/relief valve (SRV) actuation such as those present in pressure- suppression containments using water. Appendix A to this SRP section further describes loads associated with SRVs. 3.8.1-4 Revision 4 - September 2013 D. Those loads to be sustained during severe environmental conditions, including those induced by the design wind and the operating-basis earthquake (OBE) specified for the plant site. Subsection II.3.C of this SRP section defines the condition for which the OBE load is required for design of concrete containment. E. Those loads to be sustained during extreme environmental conditions, including those induced by the design-basis tornado, hurricane, and the safe-shutdown earthquake (SSE) specified for the plant site. F. 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. Other accidents involving various high-energy pipe ruptures are also considered. Loads
