Abstract
SE PRESENTA UN CANAL MEJORADO PARA CONTENER UN CONJUNTO DE COMBUSTIBLE EN UN REACTOR NUCLEAR. EL CANAL CONTIENE UNA PLURALIDAD DE VARILLAS DE COMBUSTIBLE MANTENIDAS SEPARADAS ENTRE SI POR AL MENOS UNA PLANCHA DE UNION SUPERIOR Y OTRA INFERIOR Y / O ESPACIADORES. EN EL REACTOR EL CANAL CONTIENEN LAS VARILLAS DE COMBUSTIBLE QUE SE EXTIENDEN ENTRE LA PLANCHA DE SOPORTE INFERIOR Y UNA REJILLA DE SOPORTE SUPERIOR. CUANDO EL REACTOR ESTA FUNCIONADO, EL CANAL ENCIERRA UN FLUJO DE AGUA ALREDEDOR DEL CONJUNTO DE VARILLAS EN EL QUE INTERIOR Y ASEGURA LA GENERACION DE VAPOR EN UNA FORMA PREDECIBLE. EL EXTERIOR DEL AGUA DEL CANAL ESTA A UNA PRESION DIFERENTE TIPICAMENTE INFERIOR PARA ASEGURAR LAS PALAS DE CONTROL QUE CONTROLAN EL PROCESO DE FISION FUERA DEL CONJUNTO DE COMBUSTIBLE, EL CANAL TIENE UNA SECCION DE CORTE POLIGONAL, Y MAS TIPICAMENTE UNA SECCION DE CORTE CUADRADA. CUANDO ESTA EN FUNCIONAMIENTO, LAS PAREDES PLANAS TIENDEN A ABOMBARSE DEBIDO A LOS EFECTOS PRIMARIOS DE LA PRESION PERO TAMBIEN DEBIDO A LOS EFECTOS TERMICOS Y DE RADIACCION. SE PRESENTA UN CANAL MEJORADO QUE UTILIZA UN MENOR VOLUMEN DE METAL QUE INCLUYE LADOS ONDULADOS QUE SUMINISTRAN UN REFUERZO A LAS PAREDES CONTRA LOS ABOMBAMIENTOS. LAS ONDULACIONES PUEDEN SOBRESALIR TANTO HACIA EL INTERIOR COMO EL EXTERIOR DEL CANAL. SE PRESENTA UNA CONFORMACION QUE INCLUYE SECCIONES DE LAS ESQUINAS MAS GRUESAS. ESTAS ESQUINAS GRUESAS SUMINISTRAN SOPORTES FIJOS PARA LOS LADOS DELGADOS Y AL MISMO TIEMPO MEJORAN LA RESISTENCIA A CARGAS SISMICAS. TAMBIEN SE PRESENTA UNA CONFORMACION QUE INCLUYE LADOS CON RANURAS TRANSVERSALES. EN ESTA CONFORMACION LOS LADOS SON ALGO MAS GRUESOS QUE EL MATERIAL ONDULADO (PERO MAS DELGADO QUE EL MATERIAL DE LAS ESQUINAS). LAS RANURAS TRANSVERSALES SE CORTAN PARA REDUCIR EL VOLUMEN DE MATERIAL EN EL CANAL. LAS PARTES DE ESPESOR COMPLETO DE LAS PLANCHAS LATERALES ENTRE LAS RANURAS, SUMINISTRAN LA RIGIDEZ REQUERIDA. RESULTA ASI UN CANAL QUE TIENE UN VOLUMEN MAS REDUCIDO DE METAL ABSORVENTE DE NEUTRONES QUE REDUCE APRECIABLEMENTE EL ENRIQUECIMIENTO DEL COMBUSTIBLE O INCREMENTA LA LONGITUD DEL CICLO ENTRE RECARGAS. TAMBIEN SE PRESENTA UNA CONFORMACION QUE INCLUYE LADOS CON ESTRIAS LONGITUDINALES. LAS ESTRIAS LONGITUDINALES SE CORTAN PARA REDUCIR EL VOLUMEN DEL MATERIAL EN EL CANAL. EL MATERIAL SE SEPARA DE LAS PARTES DONDE LA TENSION ES BAJA, DE TAL FORMA QUE EL EFECTO SOBRE LA RIGIDEZ DE LOS LADOS ES PEQUEÑO. DE ESTA FORMA SE OBTIENE UN CANAL QUE TIENE UN VOLUMEN REDUCIDO DE METAL ABSORBENTE DE NEUTRONES QUE REDUCE APRECIABLEMENTE EL ENRIQUECIMIENTO DEL COMBUSTIBLE O INCREMENTA LA LONGITUD DEL CICLO ENTRE RECARGAS.
