摘要

A fuel element for a boiling water nuclear reactor comprises a foot (2), a sieve plate (9), a fuel element head (1) and a bundle of longitudinal fuel rods (3,3a) that extend from the foot, as well as a water channel (4) inside the bundle. A number of partial length fuel rods are fixed to a separate holding section, which is attached to the top of the fuel element foot. The holding section also supports long fuel rods, and the holding sections are arranged on the sieve plate so that the sieve openings remain free.
