Abstract

UN MUELLE DE HOJA (11) DOBLADO EN ANGULO AGUDO (13) AGARRA SUELTO EN LAS CARAS EXTERIORES (12) DE UNA PLACA FINAL (2) DE UN ELEMENTO DE COMBUSTION DE REACTOR NUCLEAR CON UN PRIMER LADO (14) EN ANGULO RECTO RESPECTO A LA CARA EXTERIOR (12) EN UNA RANURA GUIA (15) QUE SE EXTIENDE LONGITUDINALMENTE. CON EL SEGUNDO LADO (16) ESTA SUJETO EL MUELLE DE HOJA (11) RIGIDO A LA CARA EXTERIOR (12). PARA REFORZAR LA FUERZA DEL MUELLE ESTA PREVISTO UN MUELLE DE HOJA ADICIONAL (21) QUE ESTA DOBLADO IGUALMENTE EN UN ANGULO AGUDO (23) Y QUE CON UN EXTREMO (26) ENCAJA SUELTO EN LA RANURA GUIA (15) Y CON EL OTRO EXTREMO (24) ESTA CONDUCIDO SUELTO EN EL LADO (14) DEL MUELLE DE HOJA (11).
