Abstract

A nuclear reactor fuel assembly includes an elongated fuel assembly box. Fuel rods containing nuclear fuel are mutually spaced apart in the fuel assembly box and parallel to the longitudinal direction of the fuel assembly box. A water tube inside the fuel assembly box is parallel to the fuel rods. The water tube has a lower end with an inlet opening and an upper end with an outlet opening for liquid water. A shield is fastened inside the water tube and spaced apart from both of the ends of the water tube. A flowthrough opening is formed in the shield or between the shield and the water tube for the liquid water.
