Analysis of the Vibration Characteristics of a Fuel Rod
- 1. Korea Atomic Energy Research Institute, Taejon (Korea, Republic of)
Description
In this study, the modal characteristics of a fuel rod have been analyzed by using the finite element method and the possibility of the resonance between the fuel rod and a pressure flow which originates from a coolant pump has been investigated. In order to analyze the modal characteristics of a fuel rod, the material properties of a clad and meat such as the density, Young's modulus, and Poisson ratio were determined and the finite element model of the fuel rod was validated based on the experimental results of brass fuel rods. The modal analyses were carried out for two kinds of fuel rods, one is the fuel rod which contains Zr-X%U as its meat material and the other contains Zr-Y%U. Each fuel rod was analyzed under the conditions of in-air and in-water surroundings for five different boundary conditions. The commercial code ANSYS (ver. 9) was used as a finite element analysis tool
