Abstract

DISPOSITIVO ANTI-DESPRENDIMIENTO O ANTI-DESPEGUE PARA UN ELEMENTO COMBUSTIBLE DE REACTOR NUCLEAR. CONSTA DE UNA VAINA (21) INTRODUCIDA EN EL MANGUITO DE REJILLA (15) DE LA REJILLA INFERIOR (7A), ALREDEDOR DE LOS TIRANTES (5), ESTANDO PROVISTA EN SU EXTREMO INFERIOR DE UN RESALTO INTERIOR (23), QUE ESTA BLOQUEADO ENTRE EL ADAPTADOR (6) DEL TIRANTE (5) Y LA PLACA INFERIOR (3), Y EN SU EXTREMO SUPERIOR DE UN RESALTO EXTERNO (27) QUE BLOQUEA, CON UNA HOLGURA ADECUADA, EL DESPLAZAMIENTO HACIA ARRIBA DEL MANGUITO DE REJILLA (15). LA REJILLA INFERIOR (7A) DESCANSA SOBRE UNA SERIE DE RIOSTRAS TUBULARES (29), QUE RODEAN A LA VAINA ANTI-DESPEGUE (7). EL DISPOSITIVO ANTI-DESPEGUE EVITA EL DESPLAZAMIENTO HACIA ARRIBA DEL CONJUNTO FORMADO POR LA REJILLA (7A) Y LOS ELEMENTOS COMBUSTIBLES (2).
