Abstract

UN CONJUNTO COMBUSTIBLE MEJORADO INCLUYE CABEZALES SUPERIOR (22) E INFERIOR (12), TUBOS GUIA DE BARRAS DE CONTROL QUE SE EXTIENDEN LONGITUDINALMENTE ENTRE LOS CABEZALES (22) Y (12) Y ESTAN INTERCONECTADOS RIGIDAMENTE A ESTOS, REJILLAS (16) TRANSVERSALES SOPORTADAS EN LOS TUBOS GUIA (14) A LO LARGO DE ELLOS ENTRE LOS CABEZAS (22) Y (12), BARRAS DE COMBUSTIBLE (18) QUE SE EXTIENDEN A TRAVES DE LAS REJILLAS (16) Y ESTAN SOPORTADAS POR ELLAS ENTRE LOS CABEZALES (22) Y (12) Y BARRAS DE SUJECION (34) MACIZAS QUE SE EXTIENDEN LONGITUDINALMENTE ENTRE LOS CABEZALES (22) Y (12) Y A TRAVES DE LAS REJILLAS (16). CADA UNO DE LOS TUBOS (14) TIENE UNA SECCION TRANSVERSAL SUSTANCIALMENTE EQUIVALENTE A LAS POSICIONES DE MAS DE UNA DE LAS BARRAS (18), MIENTRAS QUE CADA UNA DE LAS BARRAS (34) TIENE UNA SECCION TRANSVERSAL SUSTANCIALMENTE EQUIVALENTE A LA POSICION DE SOLO UNA DE LAS BARRAS (18). MIENTRAS QUE CADA TUBO (14) TIENE UNA SECCION TRANSVERSAL MAYOR QUE LA DE CADA BARRA DE SUJECION (34), LA SECCION TRANSVERSAL DE LA BARRA DE SUJECION ES SUSTANCIALMENTE IGUAL A LA DEL TUBO GUIA.
