nditions, force-time functions, and assumed ductility. For the time- dependent differential pressure, however, elastic behavior is required and the methods of determining an equivalent static load are accordingly reviewed. iv. Other Interior Structures Most of the other interior structures that are also reviewed are combinations of slabs, walls, beam and columns, classified as Category I structures and subject to most of the loads and combinations described in subsection I.3 of this SRP section. Analytical techniques for these structures are reviewed on the same basis as for the structures described above. 3.8.3-8 Rev. 1 - July 1981 b. For PWR Ice-Condenser Containment Internal Structures i. Divider Barrier Since the divider barrier has to maintain a certain degree of leak-tightness during a LOCA and is thus a critical structure with respect to the proper functioning of the containment, it is treated on the same basis as the containment. The loads that usually govern the design of the divider barrier are those induced by the LOCA, including the time-dependent differential pressure across the barrier and any concurrent concentrated jet impingement loads. As the divider barrier is typically a combination of walls and slabs framed together, the design and analysis procedures are of the conventional type. They are accordingly reviewed with emphasis on the assumed boundary conditions and behavior under loads. Since the dif- ferential pressure and jet impingement loadings are dynamic impulsive loads that vary with time, the techniques utilized to determine their equivalent static loads are reviewed. ii. Ice-Condenser The design of the ice-condenser and its various components may be based on a combination of analysis and testing. The ana- lytical and testing procedures that are reviewed include those for the ice baskets and brackets (couplings); the lattice frames and columns including attachments; the supporting struc- tures comprising the lower supports; the wall panels
