Abstract (en)
[origin: US5289514A] A gap between a foot part and a channel of a boiling water fuel assembly is sealed against a coolant flow by a spring being supported by a central part thereof against the channel and by sides thereof against the foot part and being clipped and/or clamped on at that location even when all of the fuel rods are removed. For this purpose, the upper edge can extend around the foot part edge or the spring may be constructed as a spring band running entirely around the foot part and being fitted into a lateral groove.
Abstract (fr)
L'espace entre le pied (400) et le boîtier (WC) d'un élément combustible de réacteur à eau bouillante est rendu étanche au fluide de refroidissement par un ressort qui s'appuie par sa partie médiane (405) contre le boîtier et par ses côtés (406, 407) contre le pied et qui peut ensuite être pincé et/ou serré à ce niveau, lorsque toutes les barres auront été retirées. A cet effet, l'extrémité supérieure peut entourer l'angle (207) du pied, ou on peut donner au ressort la forme d'un ruban entourant entièrement le pied et inséré dans une encoche latérale.
