Abstract

APARATO PARA MEDIR LA LONGITUD DE UNA PILA DE PASTILLAS EN EL INTERIOR DE UN ELEMENTO DE COMBUSTIBLE DE REACTOR NUCLEAR. EL APARATO, PROTEGIDO EN CONJUNTO POR UNA ENVOLTURA (12), CONSTA DE UNA BARRA (36) CON UN TOPE (38), DESPLAZABLE POR UN MOTOR NEUMATICO, QUE SE APROXIMA AL ELEMENTO DE COMBUSTIBLE (16), INTRODUCIENDOSE EN EL INTERIOR DE LA VAINA (18) Y CONTACTANDO CON LAS PASTILLAS (20). LA MEDIDA SE LLEVA A CABO POR UN DISPOSITIVO (44), PRESIONADO POR EL TOPE (38) SOLIDARIO A LA BARRA (36), QUE LE HACE CONTACTAR PRIMERO CON LA VAINA (18) SIN QUE SE PUEDA DESPLAZAR MAS EL ELEMENTO VERTICAL (48) DEL DISPOSITIVO (44), MOMENTO EN EL QUE SE QUEDAN ENRASADOS LOS PRINCIPIOS DE LA VAINA (18) Y LA BARRA (36), EFECTUANDOSE A CONTINUACION LA MEDIDA DE LAS PASTILLAS (20).
