Abstract
In this paper, a reactor core thermomechanical analysis method is described to provide a tool to quantify the reactivity effect of the fuel subassembly distortion in the reactor core which is a relevant problem for certain reactor types such as Sodium-cooled Fast Reactors. The importance of such an analysis was made evident by the A.U.R.N. (negative reactivity event) [1] issue in the Phenix reactor as well as by the partial core meltdown of EBR-I [2]. The proposed method consists of two major phases: 1) The simulation of the core deformation through a CAD (Computer Aided Design) based finite element solver and 2) The measurement of the reactivity effect of the c...
