swell, and subsequent hydrodynamic reaction loads Note: For loading combinations B, Service Conditions(iii), for (1)(d), (3)(c), and (4)(b), a small or intermediate pipe break accident is postulated; for all other load combinations, the design-basis LOCA is postulated. Ps C All pressure loads that are caused by the actuation of SRV discharge, including pool swell and subsequent hydrodynamic loads, if applicable Ts C All thermal loads that are generated by the actuation of SRV discharge, including pool swell and subsequent hydrodynamic thermal loads, if applicable Rs C All pipe reaction loads that are generated by the actuation of SRV discharge, including pool swell and subsequent hydrodynamic reaction loads, if applicable Yr C Equivalent static load on the structure generated by the reaction on the broken pipe during the design-basis accident Yj C Jet impingement equivalent static load on the structure generated by the broken pipe during the design-basis accident Ym C Missile impact equivalent static load on the structure generated by or during the design-basis accident, such as pipe whipping FL C Load generated by the post-LOCA flooding of the containment, if applicable Pg1 C Pressure load generated from 100-percent fuel clad metal-water reaction 3.8.2-12 Revision 3 - May 2010 Pg2 C Pressure loads generated by hydrogen burning, if applicable Pg3 C Pressure load from postaccident inerting, assuming carbon dioxide is the inerting agent, if applicable B. Loading Combinations The loading combinations for which the containment might be designed or subjected to during the expected life of the plant include the following: i. Testing Condition This includes the testing condition of the containment to verify its leak integrity. The loading combination in this case includesC D + L + Tt + Pt ii. Design Conditions These include all design loadings for which the containment vessel or portions thereof might be designed during the expected life of the plant. Such loads include
