<p>The invention relates to a debris trap for use within an end nozzle of a nuclear fuel assembly.
<??>The debris trap (42) comprises an enclosure (46) which defines a debris capturing and retaining chamber (54) and at least the downstream and upstream walls (48, 50) of which are made of a material, such as wire-mesh screen, which is pervious to liquid coolant but impervious to debris entrained therein. The upstream wall (50) of the enclosure has openings (58) sufficiently large to permit debris to pass through, and at each opening (58) it is provided with a baffle (56) which directs debris through the opening into, but deters passage of the debris through the opening from, the capturing and retaining chamber (54). The debris trap also includes means (leaf springs 72) cooperable with portions of the end nozzle to lock the trap releasably in position therein. </p> |
