<p>The invention relates to a fuel assembly, especially for a BWR, comprising a fuel-rod bundle surrounded by an outer flow channel (20), and a hollow water-cross (26) dividing the fuel-rod bundle within the outer flow channel into several mini-bundles.
<??>In a lower portion of the flow channel there is provided a flow mixing chamber (56) located beneath the lower inlet end (38) of the water-cross, which inlet end is spaced a sufficient distance above the lower ends of the mini-bundles to permit free cross flow of coolant between lower end portions of the a mini-bundles.
<??>This arrangement alleviates the problem of coolant flow maldistribution among the mini-bundles. </p> |
