Abstract
SEPARADOR CON UNA PLURALIDAD DE CELDAS PARA RETENER UNA PLURALIDAD DE VARILLAS DE COMBUSTIBLE ALARGADAS Y PARALELAS (5), QUE SE EXTIENDEN A TRAVES DE LAS CELDAS, A UN MANOJO DE VARILLAS DE COMBUSTIBLE EN UN MONTAJE DE COMBUSTIBLE DE UN REACTOR NUCLEAR. LAS CELDAS ESTAN FORMADAS POR MANGUITOS TUBULARES (1) PROVISTOS INTERNAMENTE CON SOPORTES FIJOS (2) Y AL MENOS UN ELEMENTO DE RESORTE (2) COLOCADO EN EL LADO OPUESTO DE DICHOS SOPORTES FIJOS (2). LOS ELEMENTOS DE RESORTE (3) ESTAN ADAPTADOS PARA SER LLEVADOS A UN ESTADO DE TENSION A TRAVES DEL CONTACTO CON UNA VARILLA DE COMBUSTIBLE (5) INSERTADA EN UN MANGUITO (1) Y CON FORMA DE BALLESTA (6) CORTADA DE LA PARED DEL MANGUITO (1) Y QUE, CUANDO EL MANGUITO (1) ESTA VACIO, SE EXTIENDE AL ESPACIO INTERIOR DEL MANGUITO (1). DE ACUERDO CON LA INVENCION DICHA BALLESTA (6) TENSADA CUANDO LA VARILLA DE COMBUSTIBLE (5) SE INSERTA DENTRO DEL MANGUITO (1) DESCANSA EN UNA POSICION QUE COINCIDE SUSTANCIALMENTE CON LA PARED DEL MANGUITO (1). LA BALLESTA (6)SE EXTIENDE TRANSVERSALMENTE EN RELACION AL EJE LONGITUDINAL DEL MANGUITO (1) PERMITIENDO ASI EL USO DE CELDAS DE UNA LONGITUD RELATIVAMENTE PEQUEÑA.
