Abstract

EN UN CONJUNTO DE COMBUSTIBLE TRADICIONAL, EXISTEN MEDIOS DE MANTENIMIENTO, QUE PERMITEN RECONSTRUIR LAS BARRAS DE COMBUSTIBLE DEFECTUOSAS, CONSISTENTES EN UNA ESTRUCTURA (38) QUE INTERCONECTA FLEXIBLEMENTE LA TOBERA (32) MONTADA EN LAS PROLONGACIONES TUBULARES (40), SUJETA POR UNOS MUELLES HELICOIDALES (46) A UNA PLACA DE MANTENIMIENTO (42), QUE EN CONJUNTO PERMITEN LAS DILATACIONES DE LAS BARRAS DURANTE SU FUNCIONAMIENTO, Y QUE REMATA POR UNA TUERCA DE RETENCION (78) QUE SE PUEDE DESMONTAR PARA LIBERAR EL CONJUNTO DE MUELLES BELLEVILLE (72) QUE ABSORBEN LOS IMPULSOS AXIALES.
