Abstract

EL CONJUNTO (10) INCLUYE 2 INYECTORES, SUPERIOR (22) E INFERIOR (12), ASI COMO ELEMENTOS ESTRUCTURALES (14) LONGITUDINALES QUE SE EXTIENDEN ENTRE LOS INYECTORES Y SUJETAN A LOS MISMOS PARA CONSOLIDAR EL CONJUNTO DE COMBUSTIBLE EN UNA ESTRUCTURA UNITARIA, QUE TRANSMITE UNA CARGA AXIAL A DICHOS ELEMENTOS ESTRUCTURALES UNA VEZ DENTRO DEL NUCLEO DEL REACTOR. ALGUNO DE LOS ELEMENTOS ESTRUCTURALES INCLUYE UN TUBO DE REVESTIMIENTO ALARGADO Y HUECO QUE CONTIENE MEDIOS DE SELLADO (30) Y SUJECION (46) EN ABMOS EXTREMOS DEL TUBO, Y EN UN INTERIOR CONTIENE BIOXIDO DE CIRCONIO REVESTIDO DE MATERIAL ABSORBENTES RESISTENTE AL ALARGAMIENTO, ASI COMO MEDIOS DE PRETENSION (FUELLE PRESORIZADO INTERNAMENTE O MUELLES BELLEVILLE) PARA CONTRARRESTRAR LA CARGA AXIAL Y REDUCIR EL ESFUERZO DE COMPRESION AL QUE ES SOMETIDO EL TUBO DE REVESTIMIENTO.
