Abstract

LA PRESENTE INVENCION SE REFIERE A UN CONJUNTO COMBUSTIBLE (1) Y A UN PROCEDIMIENTO PARA EL MISMO. EL CONJUNTO COMBUSTIBLE ESTA PENSADO PARA UN REACTOR NUCLEAR REFRIGERADO CON AGUA ORDINARIA Y COMPRENDE UN PRIMER Y UN SEGUNDO MIEMBROS DE ENCLAVAMIENTO (9A, 9B, 10), UNA PLURALIDAD DE ELEMENTOS ALARGADOS (3, 3A), TENIENDO CADA UNO DE LOS EXTREMOS INFERIORES DE LOS ELEMENTOS ALARGADOS UN OBTURADOR FINAL (3B). EL OBTURADOR FINAL (3B) SE COLOCA EN UNA POSICION GUIADA O ENCLAVADA EN UNA PLACA FINAL (6) QUE COMPRENDE AL MENOS DOS AGUJEROS ADYACENTES PARA LOS OBTURADORES (6B) PARA RECIBIR UN OBTURADOR FINAL (3B) CADA UNO. EL PRIMER MIEMBRO DE ENCLAVAMIENTO (9A, 9B) ESTA HECHO EN UN OBTURADOR FINAL (3B) Y TIENE UNA FORMA CONCAVA Y EL SEGUNDO MIEMBRO DE ENCLAVAMIENTO (10) ESTA DISPUESTO DE MANERA DESLIZANTE EN UN AGUJERO DE ENCLAVAMIENTO (6C) QUE ESTA ADAPTADO PARA QUE SE EXTIENDA ENTRE LOS DOS AGUJEROS ADYACENTES PARA LOS OBTURADORES (6B) Y SE ABRA EN ESTOS. EL SEGUNDO MIEMBRO DE ENCLAVAMIENTO (10)TIENE UN LARGO SUPERIOR AL LARGO DEL AGUJERO DE ENCLAVAMIENTO (6C) Y UNAS SUPERFICIES FINALES CON FORMAS DISEÑADAS PARA QUE COOPEREN CON LA SUPERFICIE CONCAVA DEL PRIMER MIEMBRO DE ENCLAVAMIENTO (9A,9B).
