Abstract

Abstract

Hold-down system is one important part of the fuel assembly, which performance has important effects on the integrity and security of the fuel assembly. In this paper, the numerical simulation method for non-linear characteristics of the leaf spring hold-down system is studied. Then the method is verified by the calculated data comparing to the measured data.
