Abstract

CONJUNTO DE COMBUSTIBLE NUCLEAR CON UN DISPOSITIVO QUE EVITA QUE LAS BARRAS DE COMBUSTIBLE TOMEN UNA FORMA CURVA, EN EL CUAL UN HAZ DE BARRAS DE COMBUSTIBLE (36) ESTA CONECTADO POR SUS EXTREMIDADES OPUESTAS CON UNAS PLACAS DE UNION, QUE INCLUYEN UNA PLACA DE UNION SUPERIOR (38) PROVISTA DE AGUJEROS (54) QUE LA ATRAVIESAN Y EN LOS CUALES ESTAN SITUADAS UNAS PROLONGACIONES (52) FORMADAS EN LOS TAPONES DE EXTREMIDAD SUPERIOR (50) DE LAS BARRAS (36). CADA PROLONGACION (52) TIENE UN DIAMETRO SUSTANCIALMENTE INFERIOR AL DEL AGUJERO ASOCIADO (54), Y ENTRE LA PARED PERIFERICA DE CADA AGUJERO (54) Y LA PROLONGACION (52) SITUADA EN EL, HAY UN ELEMENTO DE INSERCION FLEXIBLE (62) ACOPLADO CON DICHA PROLONGACION PARA SOPORTARLA DE MANERA ELASTICA A UNA CIERTA DISTANCIA DE LA PARED PERIFERICA DEL AGUJERO ASOCIADO (54). ESTA DISPOSICION IMPIDE EL BLOQUEO DE LAS PROLONGACIONES (52) EN LOS AGUJEROS (54) Y, POR CONSIGUIENTE IMPIDE QUE LAS BARRAS (36) SEAN SOMETIDAS A FUERZAS AXIALES Y SE CURVEN.
