Content:
t including R., pool swell, and subsequent hydrodynamic reaction loads. Ps --- All pressure loads which are caused by the actuation of safety relief valve discharge including pool swell and subsequent hydrodynamic loads. Ts --- All thermal loads which are generated by the actuation of safety relief-valve discharge including pool swell and subsequent hydrodynamic thermal loads. R. --- All pipe reaction loads which are generated by the actuation of safety relief valve discharge including pool swell and subsequent hydrodynamic reaction loads. Yr--- Equivalent static load on the structure generated by the reaction on the broken pipe during the design basis accident. Y. --- Jet impingement equivalent static load on the structure generated by the broken pipe during the design basis accident. Y --- Missile impact equivalent static load on the structure generated by or during the design basis accident, such as pipe whipping. F Loads generated by the post-LOCA flooding of the containment, if any. 3.8.2-8 Rev. 1 - July 1981 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 (ii) Design conditions These include all design loadings for which the containment vessel or portions thereof might be designed for, during the expected life of the plant. Such loads include design pressure, design temperature, and the design mechanical loads generated by the design basis accident. The loading combination in this case includes: D + L + P + T + R a a a (Iii) Service conditions The load combinations in these cases correspond to and include Level A service limits, Level B service limits, Level C service limits, Level D service limits and the post-flooding condition.
