1. Introduction
Fast Breeder Reactor (FBR) is a sodium cooled pool type reactor with two primary pumps and two secondary loops. A few signifi- cant structural dynamics problems such as pump induced as well as flow induced vibration and seismic excitation is very critical in a fast breeder reactor. Roof slab, which is the top cover for the main vessel forms the top shield along with rotating plugs. It provides biological and thermal shielding in the top axial direction of the reactor. It also acts as a support for various components such as main vessel (MV), Intermediate Heat Exchangers (IHX), Decay Heat Exchangers (DHX), Control Plug (CP), Primary Sodium Pump (PSP), in-vessel transfer machine, etc. The reactor assembly of prototype fast breeder reactor is shown in Fig. 1 and roof slab is shown in Fig. 2. Chetal et al [1] described the salient features of PFBR including the design of the reactor core, reactor assembly, main heat transport systems, component handling, steam water system, electrical power systems, instrumentation and control, plant layout, safety, research and development. Commercial Fast Breeder Reactors (CFBRs) are planned tobe built by 2023 after PFBR [2]. CFBR have many innovative features in reactor assembly design to achieve cost reduction. The design adequacy of PFBR components has been confirmed jointly by the scientists of IGCAR and other researchers from academia using several analyses. Chellapandi et al [3] predicted the vibration response of primary pump as well as dynamic forces developed at its supports using numerical analysis. Chellapandi et al [4] have investigated the effect of inter-connection of the nuclear reactor with the adjacent building during seismic event. Chellapandi et al [5] have investigated the seismic analysis of reactor assembly considering the fluid-structure interaction effects. An axisymmetric finite element analysis is performed with Fourier option to account for the circumferential load variations. The reactor assembly components were modeled as axisymmetric shell structures with FEM. Prakash et al [6] discussed on the experiments carried out of PFBR subassemblies for its design qualifications. The tests include pressure drop measurements, cavitation testing, flow induced vibration studies and subassembly hydraulic lifting studies. Prakash et al [7] performed the flow induced vibration studies on a scaled down model of PFBR control plug. From the experimental results, it is concluded that the control plug internals are subjected to flow induced vibration away from the resonance and the level of vibration and the bending stress induced are well
