mal conditions generated by the postulated pipe a break accident, including T , pool swell, and subsequent hydrodynamic o reaction loads. R --- Pipe reactions under thermal conditions generated by the postulated pipe a break accident, including R , pool swell, and subsequent hydrodynamic o reaction loads. P --- All pressure loads which are caused by the actuation of safety relief valve s discharge, including pool swell and subsequent hydrodynamic loads. T --- All thermal loads which are generated by the actuation of safety relief s valve discharge, including pool swell and subsequent hydrodynamic thermal loads. R --- All pipe reaction loads which are generated by the actuation of safety s relief valve discharge, including pool swell and subsequent hydrodynamic reaction loads. Y --- Equivalent static load on the structure generated by the reaction on the r broken pipe during the design basis accident. 3.8.2-11 DRAFT Rev. 2 - April 1996 Y --- Jet impingement equivalent static load on the structure generated by the j broken pipe during the design basis accident. Y --- Missile impact equivalent static load on the structure generated by or m during the design basis accident, such as pipe whipping. F --- Load generated by the post-LOCA flooding of the containment, if any. L P --- Pressure load generated from 100% fuel clad metal-water reaction. g1 P --- Pressure loads generated by hydrogen burning. g2 P --- Pressure load from postaccident inerting, assuming carbon dioxide is the g3 inerting agent.46 b. Loading Combinations These include all loading combinations for which the containment might be designed for or subjected to during the expected life of the plant. The loading combinations 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 includes: D + L + T + P t t (ii) Design conditions These include all design loadings for which the containment vessel or
