Abstract:

The parallel-plate assembly is a new type fuel element in nuclear reactors. According to the natural vibration characteristics of the parallel-plate assembly, its fluid-structure interaction vibration with nonlinear support is theoretically analyzed and numerical computed. The stability of steady-state solution near the quilibriu points is analyzed using the theory of stability. The result offers reference to the design and the safe analyse of the the parallel-plate assembly.
