loshing loads, pool swell, and its related 3.8.2-15 DRAFT Rev. 2 - April 1996 hydrodynamic loads caused either by LOCA or by SRV actuation. Other possible nonaxisymmetric and localized loads are those induced by pipe rupture such as reactions, jet impingement forces, and missiles. For the PWR ice-condenser containment, the design basis accident may result in a nonaxisymmetric pressure load due to compartmentation of the containment interior. For such localized loads, the analyses should include a determination of the local effects of the loads. These effects should then be superimposed on the overall effects. For the overall effects of nonaxisymmetric loads on shells of revolution, an acceptable general procedure is to expand the load by a Fourier series. Other methods are reviewed on a case-by-case basis for applicability to a large thin shell. b. Treatment of buckling effects Earthquake and localized pressure loads, such as those encountered in PWR ice-condenser containments, require consideration of buckling of the shell. An acceptable approach to the problem is to perform a nonlinear dynamic analysis. If a static analysis is performed, an appropriate dynamic load factor should be used to obtain the effective static load. Buckling of shells with more complex shell geometries and loading conditions than those covered by Subsubarticle NE-3133 of the Code should be considered in accordance with the criteria described in ASME Code Case N-284, as endorsed by Regulatory Guide 1.84. Buckling of shells under internal pressure should be considered in accordance with the criteria described in ASME Code Case N-284, as endorsed by Regulatory Guide 1.84.52 c. Computer programs The computer programs used in the design and analysis should be described and validated by any of the procedures or criteria described in subsection II.4.e of Standard Review PlanSRP Section 3.8.1. d. Ultimate capacity of steel containment An analysis should be performed to determine the ultimate
