Nuclear fuel element

Description

For a fuel element of a BWR with steadily cooled fuel rods and a longitudinal fuel box with rectangular cross section, the fuel rods are arranged at a distance in the meshes of an imaginary grid installed in the box with its sides running parallel to the box walls; the cross section of a prismatic water pipe arranged at a distance from the fuel box covers more than one mesh of the imaginary grid while everywhere between the water pipe and the fuel box there are meshes which are occupied by fuel rods.
