Abstract
GRUPO COMBUSTIBLE PARA UN REACTOR NUCLEAR DE AGUA HIRVIENTE.UN GRUPO COMBUSTIBLE PARA UN REACTOR NUCLEAR DE AGUA HIRVIENTE CONTIENE UNA PLURALIDAD DE VARILLAS DE COMBUSTIBLE VERTICALES (10) QUE ESTAN DISPUESTAS ENTRE UNA PLANCHA DE SUJECION INFERIOR (11) Y UNA PLANCHA DE SUJECION SUPERIOR (12), DENTRO DE UNA CUBIERTA VERTICAL CIRCUNDANTE (6). LAS VARILLAS DE COMBUSTIBLE SE PROYECTAN A TRAVES DE CIERTO NUMERO DE ESPACIADORES (13A-F) QUE ESTAN DISPUESTOS EN UNA RELACION ESPACIADA EN DIRECCION VERTICAL Y QUE JUNTAMENTE CON LA PLANCHA DE SUJECION INFERIOR Y CON LA PLANCHA DE SUJECION SUPERIOR MANTIENEN LAS VARILLAS DE COMBUSTIBLE EN UNA RELACION ESPACIADA EN DIRECCION LATERAL. EL GRUPO COMBUSTIBLE ESTA DISEÑADO PARA CONDUCIR AGUA A TRAVES DE LA PLANCHA DE SUJECION INFERIOR, POR EL ESPACIO EXISTENTE ENTRE LAS VARILLAS DE COMBUSTIBLE, DENTRO DE LA CUBIERTA VERTICAL, SALIENDO A TRAVES DE LA PLANCHA DE SUJECION SUPERIOR. PARA CONTRARRESTAR LAS TEMPERATURAS DESFAVORABLES CAUSADAS POR LA DESECACION,CADA VARILLA DE COMBUSTIBLE, EN POR LO MENOS LA PARTE PRINCIPAL DE LAS CITADAS VARILLAS, ESTA ADAPTADA PARA EMITIR UNA ENERGIA CONSIDERABLEMENTE INFERIOR EN AQUELLAS PARTES (10A, 10C, 10C) DE LA VARILLA DE COMBUSTIBLE QUE ESTAN SITUADAS INMEDIATAMENTE POR DEBAJO DE LOS ESPACIADORES (13A, 13B, 13C) EN POR LO MENOS EL TERCIO SUPERIOR DE LA LONGITUD ACTIVA DE LA VARILLA DE COMBUSTIBLE, QUE EN LAS PARTES RESTANTES DE LA LONGITUD ACTIVA DE LA VARILLA DE COMBUSTIBLE.
