Abstract

UN DISPOSITIVO (10) DE BLOQUEO INTEGRADO, REUTILIZABLE, ESTA SITUADO ENTRE UN TUBO GUIA (12) Y UNA CONTERA DE EXTREMO (14), PARA UN CONJUNTO COMBUSTIBLE NUCLEAR. UN ANILLO DE RETENCION FLEXIBLE (16) FORMA PARTE DE UN MANGUITO (22) EN EL EXTREMO DEL TUBO GUIA (12). EL ANILLO DE RETENCION (16) ES RECIBIDO EN UNA RANURA (26) PREVISTA ALREDEDOR DE LA PERIFERIA DE ESTE MANGUITO (22). UN RESORTE (20) DISPUESTO EN LA RANURA (26) REPELE EL ANILLO DE RETENCION (16) HACIA EL EXTERIOR. EL BORDE EXTERIOR DE ESTE ANILLO (16) ES RECIBIDO EN UN ALOJAMIENTO CILINDRICO (18) PREVISTO EN EL AGUJERO PASANTE DE LA CONTERA DE EXTREMO (14) Y SIRVE PARA RETENER EL TUBO GUIA (12) Y ESTA CONTERA (14) EN SU POSICION DE MONTAJE. UN MANGUITO O UN CASQUILLO PUEDE SER INSERTADO EN EL ALOJAMIENTO CILINDRICO (18) PARA FORZAR EL ANILLO DE RETENCION (16) HACIA EL INTERIOR CONTRA EL RESORTE (20) Y DESBLOQUEAR EL TUBO GUIA (12) Y LA CONTERA (14).
