Calculation of fuel rod dynamic response by state space method

  • 1. Statni Vyzkumny Ustav pro Stavbu Stroju, Bechovice (Czechoslovakia)

Description

The mathematical model is described for calculating the dynamic response of fuel rods to flowing coolant effects. The so-called state space method was used which makes it possible to find response to any arbitrary time and space course. Equations are shown for one rod, for two series-connected and two parallel-bundled rods. An example is given of a solution for one rod. The rod deflection amplitude calculated from the specific elongation is comparable with experimental measurement. (Z.M.)
