Abstract
Abstract In PFBR, Intermediate Heat Exchanger (IHX) is used to transfer heat from Primary Sodium to Secondary Sodium. A scaled down model of PFBR IHX has been designed as per design code rules of RCC-MR. In this scaled down model, main portion of IHX like tube sheets, tubes and down comer are designed innovatively. The ligament efficiency and radial & circumferential hole pattern are simulated for top & bottom tube sheets. A 2D Axis-symmetric finite element model of the scaled down model has been made and detailed structural analysis has been carried out via software called CAST3 M. Design and development of a scaled down model to simulate the deformation as well as stress distribution realistically, establishing the test setup and procedures for causing crack initiation and depicting the enhanced understanding of RCC-MR design procedures of tube sheets specific to heat exchanger are the novel features of this paper.
