Abstract
A fuel assembly has a plurality of fuel rods arranged and held in parallel with one another in the cells of spacer assemblies arranged at suitable intervals. During the assemblying and transportation of the fuel assembly, flexible sleeves are inserted in respective cells such as to separate the fuel rods from parts provided on the walls of the cells, thereby protecting the fuel rod surfaces against any damage and scratch which may otherwise be caused due to interference between the fuel rod surface and the parts provided on the walls of the cell.
