Abstract

UN CONJUNTO COMBUSTIBLE PARA UN REACTOR DE AGUA HIRVIENTE QUE COMPRENDE UNA PLURALIDAD DE UNIDADES DE COMBUSTIBLE (3A, 3B, 3C, 3D) APILADAS UNAS ENCIMA DE OTRAS, COMPRENDIENDO CADA UNA DE ELLAS UNA PLACA DE ASIENTO SUPERIOR (5), UNA PLACA DE ASIENTO INFERIOR (6) Y UNA PLURALIDAD DE VARILLAS DE COMBUSTIBLE (4A, 5B, 4C) DISPUESTAS ENTRE LA PLACA DE ASIENTO SUPERIOR Y LA PLACA DE ASIENTO INFERIOR. LAS UNIDADES DE COMBUSTIBLE ESTAN RODEADAS POR UN CANAL DE CARGA (9) QUE TIENE UNA SECCION TRANSVERSAL SUSTANCIALMENTE CUADRADA. AL MENOS PARTE DE LAS UNIDADES DE COMBUSTIBLE COMPRENDE UNAS VARILLAS DE COMBUSTIBLE DE DIAMETROS DIFERENTES Y CANTIDADES DE COMBUSTIBLE DIFERENTES. LAS VARILLAS DE COMBUSTIBLE ESTAN ADAPTADAS DE MODO QUE LA CANTIDAD DE COMBUSTIBLE Y EL ESPACIO RETICULAR DEL CONJUNTO COMBUSTIBLE SE OPTIMICEN LATERAL Y AXIALMENTE.
