nalyze the wall for such dynamic time-dependent loads with particular emphasis on modeling techniques, assumptions on boundary conditions, and behavior under loads. 3.8.3-10 Revision 3 - May 2010 iii. Refueling Pool and Operating Floor The refueling pool is assumed to be continuously filled with water to provide biological shielding above the reactor. The operating floor, which may be supported on the walls of the refueling pool on one side and on the containment shell on the other side, is a combination of reinforced concrete and structural steel. The design and analysis procedures for the refueling pool and the operating floor are conventional and are reviewed accordingly, with particular emphasis on the structural framing and behavior under loads. In cases in which the floor beams are supported vertically on the containment shell, they should be laterally isolated to minimize interaction between the containment and its interior. iv. Concrete Supports for Reactor and Recirculation Pump The design and analysis procedures used for the reactor and recirculation pump supports are reviewed in a manner similar to that used for the PWR reactor and reactor coolant system supports, as already described in this SRP section. v. Reactor Pedestal The reactor pedestal supports the reactor and must withstand the loads transmitted through the reactor supports. It is thus subjected to most of the loads described in Subsection I.3 of this SRP section and is designed and analyzed for all applicable load combinations. Because of the similarity in geometry and function of the BWR reactor pedestal to the PWR primary shield wall, their design and analysis procedures are similar. Hence, the review evaluates the reactor pedestal using the method previously discussed in this SRP section. vi. Reactor Shield Wall This cylindrical wall, which surrounds the reactor and provides biological shielding, is also subjected to most of the loads described in Subsection I.3 of this SRP section. In most
