The load combinations corresponding to these limits include the following: (1) LOCA in combination with safe shutdown earthquake and local dynamic loadings D + L + T + R + P + Y + Y + Y + E' a a a r j m (2) Multiple SRV actuations in combination with small-break or intermediate-break accident, safe shutdown earthquake, and local dynamic loadings D + L + T + R + Y + Y + Y + P + T + R + E' a a r j m s s s (e) Post-Flooding Condition This includes the post-LOCA flooding of the containment in combination with operating basis earthquake D + L + F + E L 4. Design and Analysis Procedures Design and analysis procedures for steel containments are covered in Article NE-3000 of Subsection NE of the Code, Section III, Division 1. The procedures given in the Code, as augmented by the applicable provisions of Regulatory Guide 1.57, constitute an acceptable basis for design and analysis. Moreover, for the specific areas of review described in subsection I.4 of this SRP section, the following criteria are acceptable: a. Treatment of nonaxisymmetric and localized loads For most containments, the nonaxisymmetric loads which apply are the horizontal seismic and associated sloshing 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
