Abstract

ESTA INVENCION SE RELACIONA CON UN CONJUNTO DE COMBUSTIBLE PARA UN REACTOR DE AGUA LIGERA CON UNA SECCION TRANSVERSAL BASICAMENTE CUADRADA EN LA QUE EL CONJUNTO DE COMBUSTIBLE CONSTA DE DIVERSAS VARAS DE COMBUSTIBLE (4). ESTAS SE PROLONGAN ENTRE UNA PLACA DE UNION INFERIOR (5) Y UNA SUPERIOR (6) Y UN REFRIGERANTE SE ADAPTA PARA FLUIR HACIA ARRIBA A TRAVES DEL CONJUNTO DE COMBUSTIBLE. AL MENOS UNA DE LAS PLACAS DE UNION SUPERIORES (6) O DE LAS INFERIORES (5) TIENEN ABERTURAS PARA EL FLUJO (22, 22A, 22B) PARA QUE PASE EL REFRIGERANTE Y APOYOS LATERALES (17) PARA SOSTENER LAS VARAS DE COMBUSTIBLE (4) EN DIRECCION LATERAL. LOS APOYOS LATERALES (17) ESTAN DISEÑADOS EN LA MISMA PIEZA METALICA QUE LAS ABERTURAS PARA EL FLUJO (22, 22A, 22B) Y LOS APOYOS LATERALES (17) ESTAN DOBLADOS A 90 GRADOS EN RELACION CON LA OTRA ESTRUCTURA DE LA PLACA DE UNION SUPERIOR (6) Y LA INFERIOR (5).
