Abstract

SE PRESENTA UN DISPOSITIVO COMPUESTOS POR UN MUELLE Y UN SEPARADOR PARA MANTENER LAS BARRAS DE COMBUSTIBLE (82) EN UNA POSICION RECTA EN UNA ESTRUCTURA DE COMBUSTIBLE DE UN NUCLEO DE UN REACTOR NUCLEAR. EL MUELLE (92) TIENE UNA PATILLA (106) Y DOS BUCLES (116, 118) UNO EN CADA EXTREMO DE LA PATILLA. CADA BUCLE ENCAJA UNA OREJETA (132, 134) FORMADA EN UNA FERULA (136) DEL SEPARADOR. CADA BUCLE CONTIENE UNA ONDULACION (122, 124) QUE CONTACTA CON CADA OREJETA DE LA FERULA. LA PARTE CENTRAL DE LA PATILLA TIENE UNA ONDULACION (108), O UNA PROYECCION, QUE CONTACTA CON UNA BARRA DE COMBUSTIBLE Y EMPUJA LA BARRA DE COMBUSTIBLE CONTRA UNOS TOPES (148, 152). LA FUERZA DEL MUELLE SE TRANSMITE A LAS OREJETAS DE LA FERULA MEDIANTE LAS ONDULACIONES EN LOS BUCLES DEL MUELLE. PREFERIBLEMENTE, EL MUELLE GIRA ALREDEDOR DE UNA ONDULACION (122, 124) CUANDO SE MONTA, CONTRIBUYENDO A MEJORAR LA FLEXIBILIDAD DEL MUELLE. LA ALTA FLEXIBILIDAD DEL MUELLE PERMITE EL USO DEL MISMO EN ESTRUCTURAS DE BARRAS DE COMBUSTIBLE QUE PRESENTAN UN PEQUEÑO ESPACIO ENTRE BARRA Y BARRA. ESTA CONSTRUCCION PERMITE QUE SE OBTENGA UN MUELLE DE BAJA SUPERFICIE DE AREA Y BAJO PESO, SUMINISTRANDO A SU VEZ UNA MAS BAJA ABSORCION DE NEUTRONES Y UNA MENOR OBSTRUCCION AL FLUJO DE LOS FLUIDOS.
