The fuel rods (42) of the mini-bundle form an interior array (54) of fuel rods (42A), and a peripheral array (56) of fuel rods (42B) around the interior array, the fuel rods (42A) of the interior array (54) being smaller in diameter than the fuel rods (42B) of the peripheral array (56) so as to improve their Critical heat flux performance.
