Abstract

APARATO Y PROCEDIMIENTOS PARA LA FABRICACION DE SEPARADORES PARA UN HAZ DE BARRAS DE COMBUSTIBLE NUCLEAR. UNA HERRAMIENTA DE AJUSTE INCLUYE UN MANGUITO QUE TIENE UNA REGION CENTRAL CON UNA ABERTURA AXIAL CIRCULAR Y CUATRO RESORTES DE HOJAS QUE SE PROYECTAN DESDE CADA UNO DE LOS EXTREMOS OPUESTOS DE LA REGION CENTRAL. LA REGION CENTRAL ES DE SECCION TRANSVERSAL CRUCIFORME CON PAREDES LATERALES CURVADAS ENTRE LAS PROYECCIONES DE LA SECCION CRUCIFORME. LAS CELULAS UNITARIAS SE ENCUENTRAN DISPUESTAS EN UNA BASE QUE TIENE UNAS ABERTURAS QUE SE CORRESPONDEN EN POSICION CON LOS CENTROS DE LAS CELULAS UNITARIAS EN SU ENSAMBLAJE FINAL EN UN SEPARADOR PARA UN HAZ DE BARRAS DE COMBUSTIBLE NUCLEAR. LOS DISPOSITIVOS DE AJUSTE SE DISPONEN LIBRE Y HOLGADAMENTE EN EL INTERIOR DE LAS CELULAS UNITARIAS Y LOS PASADORES SE INSERTAN PARCIALMENTE A TRAVES DE LOS DISPOSITIVOS DE AJUSTE PARA HACER QUE LOS RESORTES DE HOJAS SE EXPANDAN Y SE CONECTEN A LAS CELULAS UNITARIAS. LA ALINEACION PRECISA DE LAS CELULAS UNITARIAS PERMITE LA SOLDADURA FINAL DE LAS CELULAS ADYACENTES ENTRE SI.
