Abstract
UN CARGADOR DE VARILLA DE COMBUSTIBLE NUCLEAR (32) PARA VARILLAS DE ARRASTRE DE COMBUSTIBLE (18) EN UN ARMAZON DE MONTAJE DE COMBUSTIBLE (24) QUE TIENE UNA PINZA DE VARILLA (42) CON RANURAS (48) QUE DEFINEN MANECILLAS (54). LA PINZA (42) PASA A TRAVES DE REJILLAS (16) DEL ARMAZON (24) EN SU CAMINO HACIA UN CARGADOR DE VARILLA DE COMBUSTIBLE (34). UN EJE INTERIOR (44) DE LA PINZA (42) SE EXTIENDE SOBRE LAS MANECILLAS (54) PARA ACOPLAR UNA RANURA (66) EN LA CAVIDAD (62) DE LA CLAVIJA TOPE (38) DE LA VARILLA DE COMBUSTIBLE (18). LA PINZA (42) ES RETORCIDA ARRASTRANDO LA VARILLA (18) AL ARMAZON (24). LA PINZA (42) TIENE UNA SUPERFICIE ACHAFLANADA (74) EN EXTREMOS DE RANURAS CERRADAS (50) DE CADA RANURA (48) PARA EVITAR QUE LA PINZA (42) DAÑE UN HOYUELO (30) DURANTE LA ENTRADA EN LAS REJILLAS (16) DEL ARMAZON (24). LA PINZA (42) TIENE UNA SUPERFICIE DE PRESION AUXILIAR (76) EN EL EXTREMO (50) DE CADA RANURA (48) PARA EVITAR FALLO EN LAS MANECILLAS (54), AL FLEXIONARLAS.
