Abstract

UN NUCLEO DE REACTOR PARA UN REACTOR NUCLEAR DE AGUA HIRVIENTE CON UNA PLURALIDAD DE CONJUNTOS COMBUSTIBLES VERTICALES (40) CADA UNO DE LOS CUALES CONTIENE UNA PLURALIDAD DE BARRAS COMBUSTIBLES (10, 10A, 10B) CON UN MATERIAL COMBUSTIBLE NUCLEAR ENRIQUECIDO CUYAS BARRAS COMBUSTIBLES SE ENCUENTRAN COLOCADAS ENTRE UNA PLACA DE REFUERZO INFERIOR Y UNA PLACA DE REFUERZO SUPERIOR EN UN CANAL DE COMBUSTIBLE VERTICAL CIRCUNDANTE (1), TENIENDO CADA CONJUNTO COMBUSTIBLE UNOS HUECOS INTERMEDIOS (37A, 37B) RESPECTO A UNOS CONJUNTOS COMBUSTIBLES ADYACENTES Y POSIBLEMENTE UN CANAL INTERIOR (32) PARA LA CONDUCCION DE AGUA A TRAVES DE LOS HUECOS Y A TRAVES DEL CANAL INTERNO (SI LO HUBIERA) EN UNA DIRECCION VERTICAL DESDE ABAJO Y HACIA ARRIBA A TRAVES DEL NUCLEO Y EN DONDE AL MENOS PARTE DE LOS CONJUNTOS COMBUSTIBLES TIENEN UNAS BARRAS COMBUSTIBLES CON UN ENRIQUECIMIENTO DIFERENTE A NIVELES DIFERENTES. SEGUN LA INVENCION, CADA UNA DE LA MENOS LA PARTE PRINCIPAL DE ESAS BARRAS COMBUSTIBLES, BARRAS CENTRALES(10A), QUE EN UN CONJUNTO COMBUSTIBLE SE ENCUENTRAN RODEADAS POR UNAS BARRAS COMBUSTIBLES, BARRAS LATERALES (10B), COLOCADAS CERCA DE UN HUECO DE AGUA O CERCA DE UN CANAL INTERIOR DE AGUA, TIENE UNA RELACION DE ENRIQUECIMIENTO EN LA BARRA CENTRAL EN CUESTION RESPECTO AL ENRIQUECIMIENTO MEDIO DE LAS BARRAS CENTRALES Y LAS BARRAS LATERALES, EN UNA SECCION HORIZONTAL, QUE ES MENOR EN UNA PARTE SUPERIOR QUE EN UNA PARTE INFERIOR DE LA BARRA CENTRAL.
