Abstract

Abstract

The nonlinear phenomenon of the hold-down system is analyzed and some design response measures are proposed. Then, the method for evaluating the PWR fuel assembly leaf spring hold-down system is put forward. Last, the method is used for the design optimization of the leaf spring hold-down system of the floating NPP fuel assembly.
